1/2-20 X 2" 半狗點套件螺絲 | 合金鋼 (100 / 包)

Needed to secure a sprocket on a custom conveyor table, and the half dog point really locks into the shaft keyway without slipping. The hex socket made it easy to tighten down with a long T-handle in a cramped spot. These screws feel like quality alloy steel, not the cheap soft stuff that strips out

These are perfect for locking a pulley onto a shaft in a tight spot, the dog point centers it exactly. All 100 screws felt cleanly threaded and the hex socket didn't strip under high torque.

The half dog point tip seated perfectly into my machinery without walking off the hex drive, and the alloy steel feels solid for repeated use. These held up well under heavy torque in a confined assembly area where a standard bolt wouldn't fit.
