Fatigue Resistance in Fasteners

Fatigue Resistance in Fasteners

Simply put, you want your fasteners to hold up under many situations including conditions of changing load. However, some fasteners cannot hold up to the challenge. One of the most common forms of fastener failure is fatigue. That is why fatigue resistance and strength is something to look for in your fasteners.

A fastener can experience fatigue for a variety of reasons including assembly parameters, fastener material, geometry, and stress on the fastener. Fatigue often occurs in the first load-bearing part of the thread, and it can be detrimental to your project. This means your design must allow for screws to increase its fatigue strength. However, the fatigue strength of fine threads decreases with increased rigidity and fineness of thread, so there are some things to keep in mind with fatigue strength in your fasteners.

There are ways to increase the fatigue strength of your screws. These would include measures that reduce the effective peak stresses or prevent combined loading.

Check out some options for increasing your fatigue strength:

  • Use longer screws rather than shorter screws
  • Use screws with waisted shanks
  • Use pins or fitted shoulder screws to absorb lateral forces
  • Adequate and controlled pre-stressing of the screws

bigHead® for Wind Turbines

bigHead® for Wind Turbines

Solving your fastening problems is what bigHead does. Whether it is a difficult project or an extreme environment, we can come up with fastening solutions tailored to your needs. That is what bigHead did for offshore wind turbine maintenance hatches.

Siemens nacelle suppliers approached bigHead with a fastening problem. They recently came up with a composite hatch to replace a steel panel for covering a maintenance hatch. The only problem with the composite hatch was fastening it with traditional bolt fixings. This was a challenge because two people were required to perform the operation—one inside and one outside the nacelle. That made the operation not only less safe, but more challenging and time consuming to perform.

However, bigHead and Siemens came up with a solution through prototyping and extreme testing to make sure the fastening solution could hold up under the harsh conditions that the offshore wind turbines endured.

The solution for these offshore wind turbines was surface bonding the 316 marine grade stainless steel bigHead to the outer skin of the nacelle and passing the threaded stud section through its composite structure. This means the panel can easily be secured or removed by one person from the interior of the structure. The bigHead’s large perforated head allows a generous flow of adhesive to firmly secure it in position and its outer surface includes an over-moulded insulation layer that safeguards the nacelle against lightning strikes.

bigHead and Siemens worked together to create the perfect fastening solution for a tough problem. bigHead has been manufacturing its distinctive and leading brand of discrete bonding fasteners for over 50 years and has extensive experience across a wide range of industries where formed and molded composite products require discrete and completely secure fixing. Applications range from carbon fiber panel fixing in specialist and luxury car production to building and construction, railway carriage construction, marine and boat building, and more.

Standardization in Fastening Solutions

Standardization in Fastening Solutions

Without some type of standardization in fastening solutions, it would be impossible to get anything done. Standards allow for consumers of fasteners to know exactly what they are getting, and they ensure that materials and products are uniform.

Fastener standards are particularly important with international trade because they allow businesses to buy products from other countries resting assured that they will get the materials that will fit with their products. There are a few different companies that work to create fastener standards. These include ISO, DIN, ASTM and SAE.

ISO

ISO officially began in 1947 to develop industrial standards on an international level. Over 21,561 standards have been published by ISO since that time. ISO has members from over 162 countries and they continuously strive to standardize aspects of technology and manufacturing.

DIN

This company is a non-profit company focused on providing standardization services. DIN has been working on this for over 100 years. Over 32,000 experts from different areas come together to give you standards and specifications. DIN deals with a broad range of subjects from Acoustics to Industry 4.0 and Smart Cities.

ASTM

ASTM International was originally known as the American Society for Testing and Materials when it was formed in 1898. In 2001, the name was changed to ASTM International. This company works in the development of consensus standards, and it provides over 12,000 standards that are used around the world. This company includes over 30,000 members representing 140 countries in many industries such as metals, construction, consumer products and more.

SAE

SAE International is a global association of over 128,000 engineers and technical experts. This group focuses on providing information and standards for aerospace, commercial vehicle and automotive engineering. This group began in 1905 as a place to share and standardize automobile engineering, but in 1916, it started to include engineers from all types of mobility-related professions.

Standards are an important part of making sure your project works properly. It is a good thing that companies like these are around to help with work on standardization.

5 Benefits of Metric Dimensioning Fasteners

Metric Fasteners

When looking at fasteners, you have to decide whether you want imperial fasteners or metric fasteners. When designing new products metric dimensioning should be considered as a low cost solution to fastener assembling.

Metric fasteners most often win out over imperial fasteners and here’s why:

  1. It is a simple form of measurement with a base of whole numbers. This can help reduce the number of fasteners in a bill of materials.
  2. They are interchangeable in a global market. Parts can be assembled globally because of the availability of tools. Replacement fasteners can be purchased from local sources. Interchangeability was the key reason the automotive industry has moved to the metric form of fasteners.
  3. The metric system is the most precise form of measurement. It has been adopted by the medical industry as well as the aerospace and electronics industries.
  4. Metric thread falls between an inch course and fine thread. This allows the designer to take advantage of both thread types. It’s a better choice for vibration resistance as well as providing a larger stress area in the cross section of the screw. A commercial finish can be applied without gaging issues.
  5. Standard metric fasteners are manufactured in accordance to the ISO 4759 standard. This is a global base hole system that uses a letters and numbers system to determine a standard plus/minus tolerance for threaded fasteners.

These benefits will aid long term cost savings in design, manufacturing, and assembly, as well as product longevity in the market. If you are interested in other ways of making your business more productive, check out our product solutions and our Smart Factory Logistics.

Fasteners for Composite Materials

composites

Composite materials have become more popular to use in various projects because of their versatility. Composites are often lighter and stronger than traditional materials, so they are a go-to for projects. However, it can be a little more tricky to find fastening solutions for composite materials. Fasteners such as bigHead® and ecosyn®-BCT were created for more complex materials and situations like working with composite materials. Learn what bigHead® and ecosyn®-BCT can do for you.

bigHead®

These fasteners are made so any attachment points such as pins, nails, nuts, threads, hooks, etc. are attached to the head or base plate via a weld point. This construction allows bigHeads to be integrated into your project “invisibly.” It also means these fasteners don’t require holes in your composite materials, so your material can stay strong. These fasteners can either be embedded into the composites or surface-bonded to the composites so you don’t compromise the composite material itself.

ecosyn®-BCT

ecosyn®-BCT rivet nuts have cross holes on the shank to determine where the rivet nut will collapse to allow it to be installed in non-conventional blind applications. ecosyn®-BCT rivet nuts give you a resilient connection because it applies minimal stress around the base material so there is no damage to your materials.

Both bigHead® and ecosyn®-BCT work hard on your tough projects. These fasteners were designed to help out on those projects that are hard to handle. Using these fasteners with composite materials will help you to have a strong, stable and resilient product.

Comparison of Bossard Smart Factory Logistics Systems

Looking for a leaner and better process? Take a deeper look at Smart Factory Logistics from Bossard. Below, we break down some of our parts and services so you can decide what will be the most helpful for you and your business.

The idea behind the SmartBin part of Smart Factory Logistics is that we measure the amount of goods that you have to maximize ordering efficiency. You will be supplied with the correct amount of materials at the correct time. There are three different SmartBin options, so you can choose the ones that truly fit with your operation.

SmartBin Flex

This type of SmartBin is our most flexible option. The SmartBin Flex can be placed anywhere and it doesn’t even need a power connection. The Flex option transmits signals wirelessly for ultimate flexibility.

SmartBin Mobile

This SmartBin option will give you a mobile trolley equipped with SmartBin, making it the perfect option for changing work environments. The mobile trolleys have battery powered wireless communication.

SmartBin Classic

This option is the traditional SmartBin. It is perfect for non-mobile pools of your equipment. SmartBin can manage your parts whether they are a few grams per bin or 1,000 kg per pallet.

SmartLabel is an option for you if you cannot change or completely convert your existing system.

SmartLabel

The SmartLabel can be added to any standard bin you may have, so it doesn’t require you to change anything about the way your factory currently runs. The idea behind SmartLabel is that it will be an easy way for you to reorder products because the label has all the information to help you order parts without confusion.

SmartCard is a flexible system for assembly line delivery. Check out the specifics below.

SmartCard

Similar to the SmartLabel, this technology is another that can be very easily implemented into what you do now. When an item is out of stock, you take the RFID card associated with it and you put the card into the electronic mailbox. Then with SmartCard, Bossard will replenish your product for you. This is slightly different from SmartLabel where you have to order the product yourself.

With Bossard’s Smart Factory Logistics, each bin has a label to properly identify your part or product. How you refill that product is dependent on which system you choose from below.

Bossard Code

With this system, data is recorded with a barcode reader and sent to Bossard. Then, Bossard takes care of the replenishment of your product for you.

Do you go through certain parts quite frequently? That is where Bossard’s 2Bin system comes in.

Bossard 2Bin

You can get two standard bins for all of your parts or whatever parts you need. These bins are arranged one behind the other, so when you use up the first one, you just start using the second one. In the meantime, Bossard will collect your empty bins and refill them at regular intervals.

There are various options and various levels of Bossard’s Smart Factory Logistics. You can start small or go big, but either way you will get the Proven Productivity from Bossard. If you have questions about which parts of Smart Factory Logistics will work best for you, contact us at ProvenProductivity@bossard.com.
