HOLO-KROME 32240 5/8-11 X 3/4 英吋杯頭內六角止付螺絲 | 合金鋼熱處理黑化 (50 / 包)

The hex socket drive grips my Allen key perfectly, no wobble even at higher torque. These cup point screws hold a shaft collar in place without stripping, and the black oxide finish arrived clean and uniform across all 50.

Packed fifty to a box, these are a solid buy for anyone doing shaft work. The hex socket drive seated perfectly and the threads were clean right out of the package. No issues at all, and the price per unit is tough to beat.

The black oxide finish on these cup point screws holds up great against the occasional wrench slip, and the hex socket drive makes installation feel precise. They fit perfectly for securing a clamping collar on a small shaft I’m working with.
