Charlotte E. ★★★★★

The Phillips heads on these machine screws are deep and sharp, so my driver bit didn't cam out once during installation. I used a full box mounting plywood panels to studs, and the 1-3/4" length grabbed perfectly. Plain steel is exactly what I needed for this indoor project.

Sofia ★★★★★

I needed exactly 400 screws for a big shelving project, and the flat head sits perfectly flush in the wood. The Phillips drive grabs nicely without stripping, and these 1-3/4" lengths were just the right size for my frame.

Ava ★★★★★

I’ve been using these screws for assembling indoor shelving units, and the flat heads seat perfectly flush every time. The 1-3/4" length gives plenty of grip without poking through. For the price, getting 400 pieces is solid value.
