Chloe ★★★★★

I needed these for a jig I’m building, and the hex socket drive made installation a breeze. The threads are clean and catch perfectly every time.

Henry ★★★★★

The black oxide finish is consistent across all 200 pieces, which makes them look clean and professional in my tooling setup. Threading is smooth and they seat perfectly into tapped holes without any binding. Just wish they came in a smaller pack for occasional use.

Leo ★★★★★

I needed some good 5-40 screws for a jig I was building, and these black oxide ones fit the bill perfectly. The hex socket drive made installation a breeze, and the 200-count pack will last me a long time.
