براغي مجموعة رأس مقبس بنقطة نصف كلب 5/16-18 × 5/16" | فولاذ سبيكة (250 / عبوة)

The hex socket drive made cinching these down in a cramped spot way easier than I expected with a standard wrench. Half dog point seated perfectly on the shaft, and the alloy steel feels plenty sturdy for the torque I put on them.

I replaced a few worn-out set screws on a conveyor system with these, and the hex socket drive made final adjustments in tight spots a breeze. The half dog point grips the shaft securely without slipping.

I needed a full box for a fixture project and these set screws fit perfectly with no stripping. The half dog point held firm in the pilot holes even after repeated adjustments.
