1/2-13 X 1-1/4" 半狗點內六角止付螺絲 | 合金鋼 (100 / 包)

The half dog point design grabbed perfectly into the metal frame, no walking at all during installation. I used these on a jig project with tight clearances, and the hex socket let me get full torque without stripping the head.

The hex socket drive made installation in that tight corner a breeze, and the half dog point gripped perfectly on the shaft. Exactly what I needed for a precise set screw application.

I used these to secure a heavy bracket in a tight machinery spot, and the half dog point tip held perfectly without slipping. The alloy steel feels tough, and all 100 came threaded cleanly with no burrs.
