HOLO-KROME 76830 M14-2 X 40mm براغي ذات رأس مقبس سداسي | محرك سداسي | فولاذ سبائكي مع أكسيد أسود حراري (25 / عبوة)

I needed a high-strength bolt for a jig I was building, and these M14-2 x 40mm screws fit perfectly with no wobble. The hex socket drive made installation easier than using a standard wrench.

The thermal black oxide finish on these threads is flawless, and they seated into my precision fixture without a single hitch. I've used cheaper cap screws that stripped under torque, but these alloy steel ones feel like they're meant for the long haul.

Installed these in a jig build and the hex drive seated perfectly without any wobble. The 40mm length was exactly what I needed for that assembly.
