#5-40 × 5/8 بوصة براغي مقبس بنقطة كوب | فولاذ مقاوم للصدأ 18/8 (1000/عبوة)

I was a little worried about these screws stripping under high torque, but the hex socket drive handles it perfectly. The 18/8 stainless steel finish looks clean and professional on my latest project.

Finally found a bulk pack that actually uses 18/8 stainless instead of cheaper alloys—these set screws are holding firm in my jig with no rust after a few months. The cup point bites into the shaft nicely without stripping, which was always my issue with cheaper brands.

The hex socket drive grabbed onto my Allen key perfectly in a cramped spot where a regular wrench would’ve been useless. I’ve used maybe forty of these for securing pulleys, and the cup point bites into the shaft without stripping, which is exactly what I needed.
