Customer Reviews (4.8 / 5 · 5 reviews)

Stella C. ★★★★★

The partially threaded shaft grabbed perfectly when I snugged them into my jig frame, and the hex socket drive made torquing them down in tight spots a breeze. These feel solidly machined, not cheap at all.

Sebastian E. ★★★★★

The black oxide finish on these screws looks great and held up fine during assembly, no chips or scratches. The partially threaded design gives plenty of grip for my jig setup, and the hex socket drive seated cleanly every time.

Riley Q. ★★★★★

Substituting these into a fixture plate I’m building, and the 3/4-10 threads engaged smoothly right from the start. The partial threading gives just the right grip depth for the 4-inch length, and the hex socket drove cleanly without any cam-out. Solid hardware for jigs—these won’t be wandering off.
