3/4-16 X 1-3/4" 杯頭內六角止付螺絲 | 合金鋼 (50個/包)

The hex socket drive made installing these in a tight spot on my machinery a breeze, and the alloy steel feels solid. They fit perfectly and held firm under torque—exactly what I needed for a reliable repair.

I needed a set screw that could hold up in a tight machinery adjustment, and the Alloy Steel construction on these feels dense and tough right out of the package. The hex socket drive makes it easy to torque them down precisely without stripping.

The cup point on these screws bites into the shaft really well, no slipping even under heavy load. Pack of 50 is handy to have around for future repairs.
