Best Automotive Companies to Work For

Eager to break into the automotive industry, but not sure where to begin? We get it. Like any industry, the world of automotive companies can seem complicated and intimidating from a difference. It can be difficult to see what sets one company apart from another. How do you know which is the best car company to work for, anyway?

A Guide to Tamper Proof Screws: Types, Uses & More

If you’re wondering the difference between tamper resistant vs. tamper proof screws, you’re not alone.

High-Temperature Fasteners

Fasteners aren't always used for simple construction projects. They are often needed for developing new technologies and machines that will expose their fasteners to incredibly high temperatures. These extreme temperatures demand fasteners that can stand up to the challenging environment and keep on performing.

Full Thread vs. Partial Thread Screws

When you need a bolt, it’s tempting to find whatever’s around that meets the size specifications you need. But so much more goes into choosing the right bolt for the job.

They have the little stuff I need

You know it’s the little things that count... Like replacing hardware. I work on antique and vintage farm equipment. I have found split locking washers that are so fatigued and corroded they look like small flat washers. Until you hit them with a wire wheel. FMW has a wide variety of hardware and fast shipping. Keeping my bench stock full that keeps me turning antiques around for my customers. Need 1 washer? They can do it! Odd sized hardware? Give them a call! I am very happy with their products and service. You will be too!

Quality and service was great… Was disappointed about not having nuts and washers to fit the 7/16 inch galvanized hex head bolts. Had to grab stainless steel locally to fit them.
