Customer Reviews (4.8 / 5 · 5 reviews)

Ella Z. ★★★★★

Packed 400 to a box, every single one of these 1/4-20 flat heads fits perfectly in my jig fixtures without any binding. The slotted drive is old-school but holds torque well when I'm not worried about rust.

Stella ★★★★★

Needed these for a project where I was drilling into metal studs, and the slotted flat head sat perfectly flush every time. Threads cut clean without any binding, and the plain steel finish handled indoor work just fine.

Abigail I. ★★★★★

Had to drive a few of these through some steel brackets by hand and the slotted heads bit the screwdriver nicely without slipping off. That 2-1/4 length is perfect for sandwiching two boards with a lock washer. Plain steel is fine for my garage shelves, just don't leave them out in the rain.
