Customer Reviews (4.6 / 5 · 5 reviews)

James L. ★★★★★

I was a little worried the zinc plating would be thin, but each screw looks clean and the threads are sharp. Perfect for mounting a few metal brackets I had lying around.

Olivia J. ★★★★★

I needed a full thousand for a rack assembly project, and every single screw has clean, consistent threads that bite perfectly. The 1/4-20 sizing is exactly as specified, and the zinc plating gives them a nice, corrosion-resistant sheen without being too glossy.

Ruby Y. ★★★★★

The zinc plating on these is smooth and even, no rough edges that would snag my fingers during assembly. I used them to fasten some metal brackets to wood studs, and the 1/4-20 thread cut cleanly without stripping. For the price on a thousand pack, these are a solid value for general work.
