Vibrational Loosening and Fastening Solutions

Vibrational Loosening

The environment your product is in is a huge factor in the success and sustainability of your project. Vibration is one factor that can cause your project to fail. This is because a bolted joint has the possibility of unintentional loosening or vibrational loosening that can cause fastener failure.

The good news is, we have anti-loosening and anti-vibration fastening solutions. Some of these solutions include: ecosyn®-fix screws, the Nord-Lock bolt securing system, and TufLok®. Check out the details on these product solutions below.

ecosyn®-fix screws
This screw is made to be shake and vibration resistant. ecosyn®-fix screws consist of a large washer that is integrated into the screw head. This surface is designed to help prevent unscrewing. These screws are used in many technical appliances and electrical equipment.

Nord-Lock bolt securing system
This securing system was designed to use tension to secure critical joints that are exposed to vibrations. The Nord-Lock bolt securing system blocks the rotation of the bolt/nut and maintains the clamp load. This can offer you a sense of safety and security on your bolted joints.

TufLok® is another solution for vibrational loosening. This is a system for thread locking and thread sealing fastened joints. This system uses an elastic, wear-resistant, blue nylon patch to seal and lock as fastener into place. This system is also resistant to many chemicals which makes it a great solution for many products.

Vibrational loosening is something you want to watch out for, but if you have the right fastening solutions, you don’t have to worry. We take pride in providing proven products to increase your productivity. If you have questions, contact us at

What is Galling and How do you Prevent it?

preventing galling with bossard

By definition, galling is an interaction (usually negative) between two materials as they slide past each other. It is also known as cold welding which occurs frequently in mating threads of similar materials and surface conditions. Galling is most common with stainless steel fasteners, but can also occur with aluminum and titanium as well.

Prevention of galling simply involves changing the surface condition of one of the mating components. If dealing with aluminum, changing the alloy of one of the components is sometimes enough. Hardening to create a difference in the mating surfaces is another option. Lubricants are also good deterrents of galling.

However, there are several ways in which you can prevent or minimize galling. Check out the infographic below for those solutions.

Is it Safe to Reuse Screws?

reuse screws

For many of us, the default is to try to reuse materials from previous projects to save on costs and because we already have those materials around. However, is it safe to reuse screws?

Check out this video for some quick rules on when you should or should not reuse screws:

As the video said, do NOT reuse screws if

  • They have exceeded the yield point
  • They have wear and tear from external loads
  • They will be used in critical applications

You can reuse screws, but if you are worried about the integrity of the screw, it might be best to get new fasteners.

If you have a specific question about a project or situation, reach out to us and we can give you the benefit of our expertise. Contact us at with any questions or concerns about fastener reuse!

Rust and Stainless Steel Fasteners

Can stainless steel rust

Stainless steel is so named because it is corrosion resistant; it is a term used to define steels that are very resistant to tarnishing and rusting. In stainless steel, there is a high percentage of chromium that helps form a thin chromium oxide layer that prevents corrosion.

Many people use stainless steel because of its resistance to corroding elements. Even if the surface of your project is damaged, the chromium will react with oxygen to create a new protective layer that resists rust and corrosion.

Can stainless steel rust? While for the most part stainless steel resists rust and corrosion, if the stainless steel is not sufficiently alloyed for the environment, it cannot maintain the thin layer that helps prevent corrosion. However, stainless steel is more resistant to rust and other corrosive materials than many metals. If chosen probably your stainless steel fastening solutions should last you a long time and they should fight off corrosion.

If you are looking to replace your current fasteners or you are curious about whether stainless steel would be a good choice in your next project, contact us at We are happy to help answer your questions and find you a fastening solution that works well with your current project.

Fastener Materials: A Closer Look at Austenitic Stainless Steel

When picking the fastener for your next project, you are going to want to consider the material it is made of. Many of our options include steel fasteners. The main options you have for steel are Low Carbon Steel, Medium Carbon Steel, Alloy Steel, Stainless Steel, or Austenitic Stainless Steel.

Stainless Steel
Stainless Steel is an alloy that combines carbon grades with chromium and nickel. To be Stainless Steel, the alloy must contain at least 10.5% chromium. Austenitic is a type of Stainless Steel. Let’s take a closer look at Austenitic Stainless Steel.

Austenitic Stainless Steel
Austenitic stainless steel has a chromium content between 15% and 20% and a nickel content between 5% and 19% and offers a higher degree of corrosion resistance than the other two types of stainless. The tensile strength of austenitic stainless steel varies between 72,000 psi and 115,000 psi (500 MPa to 800 MPa). 18-8 stainless steel is a type of austenitic stainless that contains approximately 18% chromium and 8% nickel. This group includes AISI grades 302, 303, 304, 304L, and 316.

Fastener Materials: A Closer Look at Stainless Steel

Should I use Stainless Steel for fastening in my next project? That’s a good question. Fasteners come in a variety of materials and it is important to consider your project before you decide what material to use for it.

Many fastening options involve steel. The main options you have for steel are Low Carbon Steel, Medium Carbon Steel, Alloy Steel, Stainless Steel, or Austenitic Stainless Steel. Let’s take a closer look at Stainless Steel.

Stainless Steel
Stainless steel is made up of alloy steels that contain a minimum of 10.5% chromium content. The presence of chromium creates an invisible surface film that resists oxidation and makes the metal corrosion resistant. If the surface is damaged, it rebuilds itself in the presence of oxygen. It is important to understand the self-healing process because stainless steel used in a low oxygen surrounding is susceptible to aggressive influences if the protective surface layer becomes damaged.

Stainless steel is divided into three classes: Austenitic, Martensitic and Ferritic.

Stainless Steel fasteners are a good option when you need a fastener with high corrosion resistance because these fasteners will not easily deteriorate. If you have questions about Stainless Steel fasteners or need help in deciding on a fastener, contact us at Our experts can help you get the materials you need for a successful project.

Fastener Materials: A Closer Look at Alloy Steel

There are a lot of fastener options out there. When picking the fastener for your next project, you are going to want to consider the material it is made of. Many of our options include steel fasteners. The main options you have for steel are Low Carbon Steel, Medium Carbon Steel, Alloy Steel, Stainless Steel, or Austenitic Stainless Steel.

Carbon Steel
Low Carbon Steel, Medium Carbon Steel and Alloy Steel are all types of Carbon Steel. They are separated into these three groups because the mechanical properties of these fasteners are based on the amount of carbon in the fastener.

The vast majority of fasteners that are manufactured use carbon steel. This is because it is inexpensive, but also because it has a broad range of strength capabilities. Let’s take a closer look at one type of Carbon Steel: Alloy Steel.

Alloy Steel
Alloy steel is carbon steel that contains additives such as boron, manganese, chromium, silicon, etc. Additions of these elements improve the capacity of alloys to be heat treated to a wide range of strength and ductility combinations. However, the higher the strength the great the risk of hydrogen embrittlement if plated.

Alloy steels have a tensile strength in excess of 150,000 psi (1034 MPa).

SAE Grade 8 (metric class 10.9, 12.9) fasteners are made from alloy steel with AISI grades 4137, 4140, 4340, and 5140 falling into this category.
