Customer Reviews (4.8 / 5 · 5 reviews)

Alexander ★★★★★

The hex socket drive seated perfectly with my Allen wrench, no stripping even after tightening a few jigs down. For two hundred 18/8 stainless pieces in this exact 1/4-28 thread, the price feels like a steal.

Joseph ★★★★★

These bolts threaded into my tooling fixture perfectly without any binding. The hex sockets are cleanly machined so the driver fits snugly every time. I'm glad I went with stainless steel for the corrosion resistance.

Edward ★★★★★

Finally found the right length for a tooling fixture I’m repairing, and these screws thread in smoothly without any binding. The hex socket drive grips perfectly with a standard Allen key—no stripping or slippage so far.
