Avery ★★★★★

The partial threading on these is perfect for jigs where I need the shank to align parts before the threads bite. Zinc plating looks uniform across all 100, and the hex socket drive grips without any wobble.

Adam ★★★★★

I was tired of cheap bolts stripping out, so I grabbed these for a jig I'm building. The flat head sits perfectly flush, and the zinc plating looks clean and will resist rust nicely.

Chloe ★★★★★

I needed some partially threaded screws for a jig I was building, and these 1/4-20 x 2-1/2" ones fit perfectly. The zinc plating gives them a clean, corrosion-resistant finish, and the hex socket drive makes installation a breeze.
