Leo J. ★★★★★

I needed a fresh batch for a fixture rebuild and these 1/2-13s drove in cleanly with the hex socket, the nylon patch holding snug without any extra threadlocker.

Violet L. ★★★★★

The black oxide finish on these screws looks great and seems durable, and the nylon patch held tight during assembly on my fixture. They threaded cleanly into tapped holes without any binding.

Julian ★★★★★
