براغي تثبيت بنقطة كوب مقاس #1-8 × 1-1/4 بوصة | فولاذ مقاوم للصدأ 18/8 (10/عبوة)

These set screws were exactly the right length for locking a collar onto a stainless steel shaft; the hex socket took my allen key without stripping. They feel solid and corrosion-resistant for a marine environment.

The cup point bites into the shaft nicely, and the 18/8 stainless gives me confidence they won't corrode in a damp garage. I used a few of these to lock a pulley collar tight, and the hex drive let me crank them down without stripping.

The hex socket drive made it easy to tighten these into a tight spot on a jig I was repairing. No stripping or slipping even under decent torque. Happy with the stainless steel finish too.
