براغي مقبس نقطة كوب 5/8-18 × 1-1/2 بوصة | فولاذ سبائكي (50 / عبوة)

The hex socket drive made installing these in a tight engine bay a breeze, and the alloy steel feels plenty sturdy for the torque I put on them. These cup point screws seated flush without any stripping, exactly what I needed for my fixture build.

Opened the box and these set screws felt heavier and more solid than the generic ones I've used before. The cup point bit into the shaft cleanly without slipping, and the hex socket gave me plenty of grip even in a tight spot.

The hex socket drive made torquing these down in a cramped engine bay much easier than a standard screw. Cup point tip seated perfectly into the existing countersunk holes without any wobble.
