براغي مقبس سداسي بنقطة كوب 5/16-24 × 7/16 بوصة | فولاذ سبائكي مطلي بالزنك (500 / عبوة)

I needed a good grip on a motor shaft and the cup point on these really digs in without slipping. The hex drive made installation in a cramped machine frame much easier than I expected.

These set screws threaded smoothly into my workpiece without any binding, and the cup point bit firmly into the shaft to hold alignment perfectly. The hex socket drive let me torque them down easily in a cramped spot where a wrench never would have fit. Exactly what I needed for a high-vibration app

Was replacing some worn fasteners in a critical jig, and the hex socket drive let me get them tight without stripping. The zinc plating looks consistent across all 500 pieces.
