Customer Reviews (4.8 / 5 · 5 reviews)

Victoria N. ★★★★★

The nylon pellet locking feature worked perfectly on my latest jig build, holding tight even under vibration during testing. These black oxide screws look professional and the hex drive makes installation a breeze with my allen wrench.

Hannah ★★★★★

I needed a rugged set of fasteners for a jig I'm building, and these alloy steel cap screws with the black oxide finish fit the bill perfectly. The hex socket drive made installation really simple with a standard allen key.

Elizabeth ★★★★★

I needed a batch of sturdy screws for a jig build, and these came fully black oxide coated with no burrs on the threads. The hex drive seated perfectly in my allen wrench, and the nylon pellet holds tension just as described.
