براغي رأس كوب 1/2-13 × 5-1/2 بوصة | فولاذ سبائكي (25/عبوة)

Installed these in a heavy-duty jig at work, and the hex socket handled the torque without a hint of stripping. The cup point really digs in securely.

The hex socket drive on these 1/2-13 screws made final adjustments in a cramped machine frame a lot easier than I expected. Alloy steel feels solid, and the cup point tip seems to grab well without slipping. Probably the best pack of socket set screws I've bought for heavy-duty work.

The cup point really bites into the shaft, and the alloy steel feels tough enough for repeated adjustments. Only wish the package included a few more extras for the price.
