Customer Reviews (4.8 / 5 · 5 reviews)

Charlotte Y. ★★★★★

The nylon patch on these is a real timesaver—holds them in place during assembly without needing a separate lock washer. I used them for a jig build and they threaded smoothly into tapped holes. Stoked with the quality for the price.

Ava Q. ★★★★★

I needed some high-quality fasteners for a jig build, and these 3/8-24 socket cap screws have a nice, consistent finish across all 100 pieces. The hex drive engaged cleanly without any stripping, and the thermal black oxide coating looks like it will hold up well in my shop.

Chloe S. ★★★★★

The hex socket drive grips perfectly without stripping, and the thermal black oxide finish looks clean on my jig fixture. They threaded in smoothly with no binding at all.
