HOLO-KROME 08008 براغي كتف بمقبس 1/4 × 3/4 بوصة | رأس مقبس | محرك مقبس | سبائك فولاذية بأكسيد حراري أسود (25 / عبوة)

These screws feel incredibly solid, and the precision-ground shoulder works perfectly as a pivot point for a small jig I built. The black oxide finish is a nice touch, no reflections to deal with under work lights.

The hex socket drive fits my hex keys perfectly, and the black oxide finish makes them look professional on the jig I built. Only minor gripe is the package could use a sturdier container to keep screws from rattling together during shipping.

I needed these for a small indexing fixture, and the hex socket drive made installation straightforward. The black oxide finish seems durable, and the threads engaged smoothly. Only wish the package included a few more for the price.
