1/2-13 X 7/8" 半狗點內六角止付螺絲 | 合金鋼 (100個/包)

Installing these in a tight flange was a breeze thanks to the hex socket drive, and all 100 screws had clean threads without a single burr. The alloy steel feels solid, so I’m confident they’ll hold up under load.

The half dog point tip seated perfectly into my alignment holes, and the alloy steel feels tough enough for repeated adjustments. I used a few to secure a jig on my mill table, and they held firm under heavy vibration. Exactly what I needed for a precise setup.

The hex socket drive made it easy to tighten these screws in a tight spot on my latest project. The half dog point tip seated perfectly without stripping, which was a relief.
