براغي مقبس نقطة كوب مخدد M4 × 5 مم | فولاد سبائك (1000 / عبوة)

The knurled cup point on these screws really bites into the shaft, no slipping even under heavy tightening. Pack of 1000 is excellent value for the price, and the hex drive makes them easy to install in cramped spots.

I needed a high-torque set screw for a tight spot on my jig, and these knurled cup points seated into the metal without any slipping. The hex socket drive makes adjustments simple even in cramped spaces.

The knurled cup point tip held fast in a tight bracket I was securing, and the alloy steel feels solid without being brittle. A thousand pieces for this price is great for my workshop stash.
