Benefits of Speed Rivets

speed rivets benefits

Everyone wants the tool that is going to streamline their processes. Fortunately, Bossard’s semi-automatic fastening system utilized with Speed Rivets is one of those invaluable tools.

Speed Rivets are designed for a rapid installation, perfect for quickly fastening different materials and thicknesses. Electronic applications, vehicle construction, household appliances and metal cabinets are among the different applications that Speed Rivets are ideal for.

How It Works

Speed Rivets are pre-loaded on a mandrel, where they’ll be introduced into the nose of the riveting tool for continuous fastening up to 70 rivets per minute.

Tool actuation pulls the mandrel through the rivet, expanding it within the hole. This provides high clamping capability and secure joints. With controlled wear and tear of the disposable mandrel head used for the rivet expansion, rigorous clamping of all rivets is achieved.

The standard Speed rivet is capable of achieving high clamping strength thanks in large part to the formation of its closing head. Multi-speed, grooved and other types of Speed Rivets are also available depending on your material requirements.

Why Semi-Automatic Fastening?

The benefits of using semi-automatic fastening with Speed Rivets are myriad. First and foremost, semi-automatic fastening reduces the loading time of rivets in guns manually. With Speed Rivets, the need for reloading after each rivet is also eliminated.

The tools required for installation can be pneumatic or hydro-pneumatic, and can be custom-made to suit your assembly requirements. Due to the increased installation speed, you’ll see a substantial decrease in the amount of overall time required for assembly.

Few solutions available on the market allow you to increase the speed and efficiency of your processes while also maintaining both the quality and security of your products. Speed Rivets and semi-automatic fastening   the rare advancement that does it all. To learn more about the benefits of Speed Rivets, contact Bossard at ProvenProductivity@bossard.com.

Best Plating for Your Environment

Best Plating for Your Environment

When choosing a corrosion protection for hardware one must be aware of the environment and any environmental restrictions the assembly may be subject to as well as the amount of corrosion the assembly will be exposed to.

In February 2003, the European Union adopted the “Restriction of Hazardous Substances Directive” or RoHS, as it is commonly referred to. The RoHS directive aims to restrict certain dangerous substances commonly used in electronic equipment. This practice has now been accepted worldwide by the medical, food, farm implement and auto industries, as well.

The following are the most common corrosion protections:

Hot Dip Galvanizing
Heavy zinc layer, usually 80-100 microns thick with the minimum practical thickness around 40 microns. Applied by dipping parts into molten zinc, this process is not recommended for higher strength grades. It is difficult to maintain thread tolerances and usually means over tapping the threads of the nut or female mating part. However, this is an excellent choice for outdoor use, such as highway construction.

Electrolytic Plating
The most common method for commercial hardware. Several different metals can be used with the most common being zinc. Other metals could be nickel, copper, etc. When used on fasteners with property class 10.9 (Grade 8) and case hardened fasteners such as tapping and thread forming screws, the risk for hydrogen embrittlement increases. The plating thickness may vary from 3-15 microns.

Mechanical Plating
An alternative to electro plating that can be used on materials sensitive to hydrogen embrittlement. It is simply a method of blasting the fasteners with very small pigments and a carrier, causing a fusing of plating metal (zinc, nickel, aluminum etc.) to the fastener surfaces. The thickness is about the same as for electro plating.

Coatings
The most common being manganese or zinc often used in high strength applications. Recent developments in engineering class coatings promises to solve hydrogen embrittlement but also improves the control of lubricity, which is very important in controlling torque tension relations.

Each type of corrosion has its own advantages and disadvantages. That’s why it is import to understand the environmental and mechanical requirements for each application before deciding on a finish.

Property Class Versus Grades

Property Classes

When deciding what size or type of fastener best fits your needs, it is important to know the strength of the fasteners you’re choosing from. This can identified by the grade or property class associated with the fastener. Inch fasteners, which are more common in North America, will have a grade or a rating from the American Society for Testing and Materials. Property classes are used for metric fasteners. (more…)

Why Do Fasteners Self-Loosen

why fasteners self-loosen

Why Loosen?

Loosening fasteners have been an issue for decades. Because a fastener coming loose can often lead to an accident, it is important to understand the possible factors that could contribute to the loosening of a fastener.

Typical applications for fasteners are in clearance holes, and the tightening of the fastener helps maintain the structural integrity. If loosening occurs, the preload is reduced or eliminated completely, resulting in structural failure. (more…)

Benefits of Using bigHead® Fasteners

bigHead fasteners benefits

Some people will tell you that without a solution, there is no problem. For the engineers at bigHead®, there is no problem without a solution. Back in 1966, engineers were tasked with designing a fastener that could fasten in composite material with the same strength and efficiency of traditional fasteners. The result was a fastener with a perforated head perfect for locking the product into position by using a structural adhesive. before being welded to a variety of studs, nuts, collars, pins and other fixings. And thus, the first bigHead® fasteners were born. (more…)

Standard Methods for Testing Hydrogen Embrittlement

Methods for Testing Hydrogen Embrittlement

What is Hydrogen Embrittlement?

Hydrogen embrittlement by definition is: A condition of low ductility in metals resulting from the absorption of hydrogen. The mechanism begins with hydrogen atoms diffusing through the metal. When these hydrogen atoms re-combine in minuscule voids of the metal matrix to hydrogen molecules, they create pressure from inside the cavity they are in. This pressure can increase to levels where the metal has reduced ductility and tensile strength, up to where it can crack open, in which case it would be called Hydrogen Induced Cracking (HIC). High-strength and low-alloy steels, aluminum, and titanium alloys are most susceptible. (more…)

Making Stainless Steel and Its Benefits

Making Stainless Steel Fasteners

In many applications, stainless steel fasteners are often recommended for use for a number of reasons.

To understand why stainless steel fasteners are so popular and beneficial for many applications, we must first examine how stainless steel is created. Stainless steel is the term used to define steels that are highly resistant to rusting and tarnishing. These steels also house two or more separate elements that are alloyed together. The simplest way for stainless steel to be created is with the addition of chromium to ordinary steel, making it corrosion resistant. The alloy that the steel is mixed with contributes to the mechanical properties of the stainless steel and how well the stainless steel resists corrosion. (more…)
