HOLO-KROME 76482 براغي ذات رأس أسطواني M16-2 X 160mm | محرك سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (10/عبوة)

Put these in a jig I was building and the threads cut super smooth—no binding at all. The 160mm length was perfect for getting through the thick steel plates I was clamping together.

The black oxide finish on these is really uniform, not splotchy like some cheaper packs I've gotten. Threads engaged cleanly into my tapped holes and the hex socket drive seated without any wobble. Solid choice for jigs that see daily use.

Installed these on a welding fixture and the black oxide finish held up great against the heat. The hex socket drive made it easy to torque them down precisely.
