براغي تثبيت برأس كوب بنقطة 1/2-20 × 3/8" | فولاذ سبائكي (100 / عبوة)

I needed a hex socket drive for adjustments in tight spots, and these screws fit the bill perfectly with their alloy steel construction. They’re holding up great so far without any stripping.

The cup point on these set screws really bites into the shaft firmly, which is exactly what I needed for a high-torque application. Installed a batch yesterday and they held perfectly without any slipping.

These held tight when I was torquing down a stubborn fixture in a cramped engine bay, the hex drive really helps in those tight spots. The cup point tip seated perfectly without stripping, and the alloy steel feels solid for the price.
