7/16-14 x 7/8" 滾花杯端內六角止付螺絲 | 合金鋼 (100 / 包)

The hex socket drive made it easy to tighten these set screws in a cramped spot on my milling machine. They feel solid and well-made, and the alloy steel gives me confidence they'll hold up under vibration.

The knurling on the cup point grips the shaft way better than smooth set screws I’ve used before, and the hex socket let me torque it down in a cramped spot without stripping. All 100 came in the package with clean threads, no burrs. Solid hardware for the price.

The knurled cup point really locks down alignment on my machinery without slipping, even under vibration. The alloy steel feels solid and should last through repeated adjustments. Exactly what I needed for a tight-spaced assembly.
