Jason G. ★★★★★

I needed a longer partially threaded bolt for a jig I’m building, and these 2-5/8" screws fit perfectly without the full length threading getting in the way. The hex socket drive gave good torque without stripping. Solid quality for the price.

Harper T. ★★★★★

The black oxide finish on these screws looks great and seems durable—perfect for the jig I'm building. They fit my hex driver snugly and the partial threading worked exactly where I needed it on the assembly.

Ava J. ★★★★★

Needed a batch of partially threaded cap screws for jig builds, and these fit the bill perfectly. The hex socket drive engages cleanly, and the 2-5/8" length matched my fixture depth exactly.
