براغي تثبيت بنقطة كوب M20 × 30 مم | فولاذ سبائكي مطلي بالزنك (50 / عبوة)

Used these for a jig I'm building and the cup point grips the shaft way better than the flat-tip ones I had before. The zinc plating hasn't chipped even after torquing them down hard.

The hex socket drive made these so much easier to tighten in a cramped engine bay compared to using an Allen key on standard screws. The zinc plating looks uniform and seems durable enough for industrial use, and all 50 pieces had clean threads right out of the package. Exactly what I needed for sec

Finally, some set screws with threads that actually look clean and cut all the way—no burrs or rough spots. The hex socket engaged my driver perfectly, making installation into a blind flange a breeze.
