Hannah Y. ★★★★★

I needed something small but strong for securing a gear to a shaft, and the 18-8 stainless steel in these #4-40 x 1/2" cup point screws feels much more robust than I expected from such tiny fasteners. The socket drive made installation straightforward with a hex key, and 50 pieces should cover multi

Avery L. ★★★★★

These little stainless screws are a perfect fit for the pulleys on my project, and the socket drive made installation far easier than a standard hex key. They feel very solid for their small size.

Michael ★★★★★

Finally, a #4-40 set screw that actually holds a pulley tight on a small shaft, and the hex socket gives a solid grip without stripping. The 50-pack means I have backups for my next few projects without another run to the hardware store.
