HOLO-KROME 32184 3/8-16 × 1-1/2 بوصة براغي تثبيت ذات نقطة كأس | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

Installed these on a motor shaft today and the hex socket drive made it easy to torque them down precisely. The 1-1/2" length was just right for my assembly.

The thermal black oxide finish on these set screws provides a nice, uniform look that resists corrosion better than the plain steel ones I've used in the past. I needed a batch for jig assembly, and the cup point really helps them sit flush against the workpiece.

The cup point bites into the shaft nicely without stripping, and the thermal black oxide finish has held up through a few greasy installs. Exactly the clamping grip I needed for a machine rebuild, and the 100-count box means I won't run short mid-project.
