3/4-10 X 2-1/2" 內六角螺絲 | 平頭六角驅動 | 全螺紋 | 合金鋼鋅鍍 (25入/包)

The zinc plating is nice and even, so they’ll hold up in my cramped toolbox without any surface rust worries. Fit the hex socket wrench perfectly with no slop, and the full threading grabbed cleanly in the steel plate I bolted down.

I used these for a jig I’m building, and the flat head sits flush perfectly. The hex drive worked well with my Allen wrench, no stripping.

The zinc plating on these screws is holding up perfectly so far, even in my slightly damp workshop. They threaded smoothly into hardened steel without any binding during my jig build.
