براغي مقبس نقطة كوب 5/16-18 × 7/8 بوصة | فولاذ سبائكي مطلي بالزنك (250 / عبوة)

I’ve been using these set screws on a custom workbench jig, and the hex socket drive makes tightening in tight spots effortless. The zinc coating seems durable enough for shop use, and the pack of 250 means I won’t run out mid-project.

The cup point tip grabbed perfectly into the metal frame without stripping, even under heavy torque. These little screws held firm after a day of vibration on my workshop jig. Exactly what I needed for a secure, flush fit in tight spots.

The hex socket drive made cinching these down in a cramped bracket far easier than I expected for the price. The cup point bit into the shaft cleanly and held firm under vibration, and the zinc coating looks uniform across all 250 pieces.
