5/16-18 X 3/4" ハーフドッグポイント六角穴付き止めねじ | 合金鋼 (250個/パック)

The hex socket drive makes it easy to tighten these in tight spots without stripping, and the half dog point tip holds alignment perfectly during assembly. Exactly what I needed for metal framing work.

Using these in a jig fixture and the half dog point seats perfectly every time, no wandering. The hex socket drive makes adjustments in tight spots a breeze, and a full box of 250 means I won't be reordering for a while.

After fighting with a stripped hex head on my jig, these alloy steel screws bit in clean and held fast. The hex drive let me really torque them down without cam-out.
