براغي تثبيت بنقطة كوب مع رقعة نايلون 1/2-13 × 1-1/2" | فولاذ سبائكي (100 / عبوة)

The cup point bites into the shaft firmly, and the nylon patch locks them in place without needing threadlocker. I used these on a conveyor roller adjustment, and they held solid under vibration. Exactly what I needed.

The hex socket drive made seating these in a tight spot under the lathe a breeze, and the cup point bit in firm enough that I didn’t have to re-tighten after a full day of vibration. Nylon patch held its position right out of the bag, which saved me from reaching for the Loctite.

I’ve been using these set screws for a few weeks now, and the hex socket drive makes tightening them in tight spots really easy. The cup point grips the shaft firmly, and the nylon patch keeps them locked in place. Solid choice for heavy-duty projects.
