Hex Hd Cap Screw

Truck frames, construction, wind energy, and let’s not forget maintenance and repair… BigBolts Hex Head Cap Screws truly do it all and enjoy every minute of it. They “go big” too, up to 20 inches long, 2 inches diameter and GRs 5, 8, BD and L9. Used in all industries and in a broad range of capacities. If you’ve got a question for our team of gurus (or “application engineers” if you want to be technical) give us a shout. We won’t steer you wrong.

And don’t forget – our return policy lets you send them back 365 days a year…but we’re pretty sure you’ll want to keep extras around for unexpected maintenance needs! These bolts are designed to be used with nuts. Log-In here to place your order.
