HOLO-KROME 08082 براغي كتف بمقبس 1/2 × 2-1/4 بوصة | رأس مقبس | محرك مقبس | فولاذ سبائكي بأكسيد حراري أسود (25 / عبوة)

Needed some precision shoulder screws for a jig I'm building, and these have been spot on. The hex socket drive makes installation easy with an Allen key, and the thermal black oxide finish looks like it'll resist rust well.

Using these as precision axles for a jig I built, the ground shoulder was dead-on straight and slid into bearings with zero slop. The black oxide finish also seems tough enough to resist shop grime.

The precision ground shoulder made these screws work perfectly as a pivot point in my jig, and the hex socket drive was easy to torque down. Only needed three for my project, but having a full pack of 25 is great for future builds.
