7/16-14 X 1" カップポイント六角穴付き止めねじ | 合金鋼亜鉛メッキ (100/パック)

These hex socket screws drove into the steel perfectly with a 3/16" Allen key, and the cup point design made them self-aligning in the pilot hole. The zinc plating looks clean and should resist rust in my workshop jig.

The cup point bites into the shaft firmly without stripping, even when I torqued it down hard with a hex key. Zinc plating looks clean and uniform across all 100 pieces, and the threads ran smooth right out of the bag.

The hex socket drive made cinching these down in a tight spot way easier than fumbling with a wrench. Zinc plating looks clean and should hold up fine in the garage.
