Andrew ★★★★★

Just got these for a small jig I'm building and the brass finish looks sharp against the steel parts. The #4-40 threads are cut clean and they seat perfectly in the hex driver without any wobble, nice to have a full 3/4" of grab in the assembly.

Avery P. ★★★★★

The hex socket drive on these little brass screws is perfect for tight spaces where a regular driver won't fit. Used them on a small precision assembly and they threaded cleanly without any binding.

Sophia ★★★★★

Pulled these out for a small jig I was building and the brass finish adds a nice touch against the steel parts. Threads cut cleanly into the tapped holes without binding.
