Emily ★★★★★

These cup point screws held tight when I was adjusting a jig in a cramped spot, and the hex drive bit into the alloy steel without stripping. The 3.5-inch length was just right for the deep assembly I was working on.

James J. ★★★★★

The hex socket drive really lets me crank these down into tight spots without stripping — perfect for securing a shaft in a small mechanism. The alloy steel feels tough and the cup point bites in firmly once seated.

Hazel ★★★★★

I needed longer screws for a tight adjustment job, and the hex socket drive on these made it easy to get them seated flush without stripping. The cup point tip grabbed cleanly even in the tight corner I was working in.
