Customer Reviews (5.0 / 5 · 5 reviews)

Brian U. ★★★★★

These bolts threaded smoothly into my 5/8-11 tap without any binding, and the 4-1/2 inch length was perfect for the heavy equipment mount I was repairing. The B7 alloy steel feels much tougher than the grade 5 stuff I've used before.

Ava G. ★★★★★

I was impressed with the hex head’s grip during installation, and the B7 alloy steel feels sturdy enough for heavy machinery use. These 4-1/2 inch cap screws fit perfectly on our assembly line without stripping.

Emily ★★★★★

These partially threaded bolts worked perfectly for mounting a heavy gearbox—the 4-1/2" length gave me just enough grip without bottoming out. The B7 alloy feels seriously tough compared to the grade 5 stuff I usually grab.
