James ★★★★★

The low head profile cleared a tight spot on my mill where standard cap screws would've fouled, and the black oxide finish gave them a nice grip in the wrench. Threads ran smooth into my tapped holes without any binding. Packed a hundred for the price of a hardware store's dozen, which is hard to ar

James S. ★★★★★

Needed a low-profile head for a tight jig clearance, and these 1/4-20 x 1-1/2" screws fit perfectly with the hex socket drive making installation a breeze. The thermal black oxide gives them a clean, durable look that should hold up well in my shop.

Avery Z. ★★★★☆

Used a handful of these for a jig setup and they threaded cleanly into tapped holes without any binding. The low-profile head is perfect for tight clearance spots. Only wish the hex socket was a touch deeper for better bit engagement.
