5/16-18 x 3" 半狗點內六角止付螺絲 | 合金鋼 (100顆/包)

These set right into the threads without binding, and the half dog point gives a solid bite on the shaft. The 3-inch length was perfect for my jig fixture build.

Needed a longer set screw for a machine guard adjustment and these 3-inch half dog points fit the bill perfectly. The alloy steel feels really sturdy and the hex socket grabs tight without stripping.

The hex socket drive made it easy to torque these into a tight fixture without stripping. The half dog point seated perfectly in the alignment hole, and the 100-pack means I’ve got spares for future projects.
