Riley ★★★★★

The slotted drive on these #4-40 screws grabbed my screwdriver nicely without slipping, and the 18/8 stainless steel feels solid. I used them to secure a small metal panel, and all 200 pieces came cleanly threaded with no burs.

Samuel N. ★★★★★

Just what I needed for fastening an aluminum panel to a steel enclosure, and the 18/8 stainless feels solid enough to trust outdoors. The slotted heads are easy to drive with a standard screwdriver, and all 200 arrived clean and uniform.

Nicholas W. ★★★★★

Grabbed a pack for mounting a small instrument panel and the 18/8 stainless finish is noticeably smoother than the last batch of generic screws I used. Slotted heads are cut cleanly, no wobble from the driver, and all 200 came out of the bag with zero duds.
