Customer Reviews (4.4 / 5 · 5 reviews)

Edward ★★★★★

Needed a good batch for jig repairs and these are exactly what I was hoping for. The hex socket drive made installation smooth with no stripping.

Chloe O. ★★★★★

I was pleasantly surprised by the quality of the threads on these screws—they started smoothly into my jig without any binding. The 18/8 stainless steel feels durable enough for repeated use in my shop fixtures.

Claire ★★★★★

I’ve been using these screws for building jigs and the 18/8 stainless steel holds up way better in the shop than the cheap zinc ones I had before. The hex socket drive gives a solid, secure fit with no stripping. Definitely worth it for a bulk pack of precision fasteners.
