The hex socket drive bites well—no stripping even when I tightened them into a steel jig with an allen key. The black oxide finish gives them a clean, uniform look, and 200 pieces means I’ve got plenty left for future tooling projects.

I needed a solid fastener for a jig I’m building, and the nylon patch on these screws holds them tight without needing a separate lock washer. The black oxide finish looks clean and professional, plus the 200-count package is great value for the price.

The nylon patch on these #8-32 screws is a lifesaver—they hold tight even under vibration without needing a separate lock washer. I used them to rebuild a jig fixture and every one threaded smoothly into tapped holes without binding. Exactly what I needed for precision tooling work.
