براغي ضبط رأس مقبس مخدد 3/8-16 × 3/4 بوصة | فولاذ سبائك مطلي بالزنك (100/عبوة)

I needed these for a tight motor mount adjustment and the hex socket drive made it easy to apply good torque in a cramped spot. The zinc plating has a clean, even finish that should resist rust in my shop.

The knurled cup point grips the shaft way better than standard flat tips, and the zinc coating has held up through two months of machine adjustments without a speck of rust. Threads cut cleanly into the tapped hole, no binding at all.

The knurled cup point gripped my shaft collar perfectly without slipping, even under vibration. I drove the hex socket hard with an Allen key and the zinc coating didn't flake off.
