The zinc finish on these steel set screws looks clean and uniform, and the hex socket grip was tight enough that none of the 50 stripped during my shaft collar installs. They held firm against rotation exactly as described, so I’ll definitely grab another pack when I run low.

The hex socket drive made installation effortless with just an Allen wrench. These steel set screws feel solid and hold firmly against rotation—exactly what I needed for a shaft assembly.

Installed these on a motor shaft to lock a sprocket in place, and the hex socket drive made tightening them in a tight spot much easier than a slot head would have. The steel feels sturdy enough for the job.
