Anatomy of a Fastener

Anatomy of a Fastener

Our products speak for themselves; we produce quality fasteners efficiently and better than any other company out there. So, what’s our Proven Productivity-secret to manufacturing a fastener that our customers trust? We’ve conducted a list to break down the “anatomy” of our fasteners to give you a peek inside the production process.

Cold Forming
What is it? Cold forming is the process of forging metals at near room temperatures with high speed and pressure.

Why do we use it? This cost-efficient use of raw material moves the metal so wire can be smaller than the finished part. Cold forming also offers us an uninterrupted grain flow.

The alternative to cold forming is “screw machining.” This method interrupts that grain flow we mentioned. In addition, the blank needs to be as wide as the largest diameter of the product and as long as its final length.

Heading Process
What is it? Heading is the process of forming the fastener—it is pushed through what we call a “die.” The die presses the mold, shaping our fastener precisely and perfectly. Our process includes the ratio of one die to one blow heading, one to two, and two to three processing. This particular operation plays a large factor in the cost-effectiveness of cold forming, as well as it contributes to the strength of the final result.

Materials
Here at Bossard, Proven Productivity, we use a wide variety of materials in the production of our fasteners. It takes high quality products to produce high quality products and that’s exactly what we do in the manufacturing of Bossard fasteners.

• Low carbon steel
• Medium carbon steel
• Alloys
• Aluminum
• Stainless steel
• High technology alloy
• Tool Steel

Thread Rolling
Last, but certainly not least, our fasteners enter the process of “thread rolling.” This involves rolling the threads on the shank using thread dies. A threading die is a block with a slanted ridge in the shape of threads.

Now that you have caught a glimpse into the manufacturing of your favorite fastening materials, you can see how it takes care and precision to produce a brand you love. We would love to hear your questions and comments, so contact us anytime at ProvenProductivity@bossard.com.
