براغي مقبس كوب مقاس 5/16-24 × 1 بوصة | سبيكة فولاذ مطلية بالزنك (250 / عبوة)

Installing these in a cramped gearbox was a breeze thanks to the hex socket drive, and the cup point bit in nicely without stripping. The zinc plating looks uniform and clean, too. For a 250-pack, the price per screw is hard to beat.

These cup point screws held tight without stripping even after repeated adjustments on a jig fixture. The hex socket drive gave me plenty of torque in a cramped spot, exactly what I needed.

Needed to swap out a seized set screw on a machinery guard, and the hex socket drive made tightening in that confined spot a breeze. The cup point bit into the shaft nicely, and the zinc coating on these 250 pieces should hold up well in our shop.
