Customer Reviews (4.8 / 5 · 5 reviews)

Hannah R. ★★★★★

The hex drive seated perfectly on my Allen wrench with zero wobble, and the 18/8 stainless finish looks clean against my fixture plates. I ordered a hundred for a tooling project and every single one threaded smoothly without binding.

Ellie ★★★★★

I used these on a jig I built for the shop, and they tightened up nicely without any stripping. The 18/8 stainless steel feels solid compared to the cheap zinc ones I had before.

James ★★★★★

Finally, a socket head cap screw that doesn't strip on the first use—the hex drive on these feels precise and holds tight. Used them to replace worn bolts on a shop press I'm fixing, and the 18/8 stainless steel finish gives me confidence they'll hold up longer than the originals.
