HOLO-KROME 76392 براغي رأس مقبس M12-1.75 × 65 مم | محرك مقبس سداسي | فولاذ سبائكي معالج حراريًا بطبقة أكسيد أسود (50 / عبوة)

The black oxide finish on these screws gave my fixture a professional look, and the hex drive made installation straightforward without any stripping. They’ve held tight under heavy use in my tooling setup, so I’m satisfied with the purchase for the price per pack.

I needed some solid M12 bolts for a jig I've been building, and these 65mm socket caps fit perfectly with zero slop in the threads. The black oxide coating seems tough enough to handle a bit of shop grime without rusting.

The black oxide finish looks proper on these, not cheap like some batches I've had. Threads are clean and the socket drive seated a 6mm hex wrench without any slop. Fifty of them is a solid lot for the shop.
