M14-1.5 X 40mm 內六角螺絲 | 內六角驅動 | 全牙 | 12.9級合金鋼鍍鋅（50 / 包）

Installed these in a jig fixture for a production run and they torqued down evenly without any stripping. The hex socket drive takes an Allen key perfectly with zero wobble.

The hex drive on these M14 screws lets me really torque them down into my jig without stripping, and the zinc coating has held up perfectly so far. They threaded cleanly into my tapped steel plate, which is always a relief with these larger fasteners.

These hold up great under load on my shop press jig; the hex socket drive made installation much easier than a standard bolt head. The zinc plating gives them a clean, consistent finish right out of the package.
