براغي تثبيت بنقطة كوب مخددة مقاس 3/8-24 × 3/4" | فولاد سبائكي مطلي بالزنك (100 / عبوة)

The knurled cup point really bites into the shaft—no slipping even after a few days of vibration. Zinc plating looks uniform and hasn’t rusted yet in my damp garage. Only wish the hex socket were a touch deeper for the shorter wrench.

The hex socket drive made these easy to torque down in a cramped spot where I couldn't get a wrench. The knurled cup point gripped the shaft firmly without slipping, and all 100 pieces came clean and ready to use.

The knurled cup point digs in nicely without slipping, and the zinc plating seems durable enough for repeated adjustments. These fit perfectly in my setup and held tight under vibration. Exactly what I needed for this job.
