Customer Reviews (4.4 / 5 · 5 reviews)

Abigail ★★★★★

Packed these flathead screws snugly into some wooden jigs for a shop project, and the slotted drive held up well under my manual driver. The 3-inch length was just right for a couple of thick brackets I was mounting.

Adam ★★★★★

I needed exactly 200 of these for a cabinet hinge jig I was building, and the flat head countersinks flush without any fuss. The slotted drive is old-school but bites well with a standard screwdriver.

Sebastian ★★★★★

I’ve been using these 1/4-20 x 3-inch screws for mounting brackets in my workshop, and the slotted drive makes them easy to tighten with a standard screwdriver. The plain steel finish holds up fine for indoor use, and the 200-count package is a solid value for the price.
