Frequently Asked Questions

Get answers to common inquiries about our products and services.

Are Allen Bolts and Hex Bolts the same?

While both are used for fastening, Allen bolts (socket head) are driven with an Allen key internally, whereas hex bolts have an external hex head driven with a wrench. They serve different mechanical needs.

What is the difference between a washer and a flange nut?

A washer is a separate component used to distribute load, while a flange nut has an integrated flange that acts like a built-in washer, saving assembly time and space.

What are the 4 types of bolt heads?

The four common types are: Hex Head, Socket Head (Allen), Round Head, and Flat/Countersunk Head. Each serves specific installation and aesthetic requirements.

Do you offer custom fasteners?

Yes, we specialize in custom non-standard bolts, screws, and stamping parts tailored to your specifications and industry standards.
