M24-3 X 70mm 內六角圓頭螺絲 | 六角插座驅動 | 全螺紋 | 12.9級合金鋼鍍鋅 (10 / 包)

Pulled these out for a tooling fixture and the hex socket fit perfectly, no slop. The zinc plating on the threads is even and smooth, so they should hold up well in the shop. Exactly the strength I needed for that heavy clamp assembly.

I needed precise hardware for a jig repair, and these Class 12.9 socket cap screws threaded smoothly into place without any binding. The hex socket drive let me torque them down evenly with an Allen key, and they feel rock-solid in the assembly.

The zinc plating on these is flawless, no flaking or rough edges, and they’ve held up perfectly in my jig fixture. Threads cut cleanly with zero binding, and the 12.9 alloy steel feels rock solid for the torque I’ve put on them.
