براغي رأس مقبس HOLO-KROME 76219 M6-1 × 100mm | قيادة مقبس سداسي | سبائك صلب مع أكسيد أسود حراري (100/عبوة)

The black oxide finish on these is really clean and seems durable—much nicer than the bare steel screws I’ve used before. They fit perfectly in my tooling fixture and the hex drive makes tightening them a breeze.

I needed long M6 bolts for a custom jig, and these 100mm socket cap screws fit perfectly, the hex drive made installation a breeze using a simple Allen key. The black oxide finish looks clean and professional against the steel.

I’ve been using these in a jig setup for a few weeks now and the hex socket drive is a real time-saver when tightening them down. The 100mm length gives just enough reach for thicker clamping blocks.
