HOLO-KROME 08093 براغي كتف مقبس 1/2 × 3-3/4 بوصة | رأس مقبس | محرك مقبس | فولاذ سبائكي أسود حراري (25 / عبوة)

The hex socket drive gives a nice, positive grip with the wrench, and the black oxide finish feels durable out of the box. Used one to replace a worn pivot pin on a jig, and the shoulder fit perfectly.

The precision ground shoulder on these is exactly what I needed for a clean bearing surface on a custom pivot setup — it fits snug with zero wobble. The thermal black oxide finish also gives them a tough, slick feel that should hold up well in a greasy environment.

The precision ground shoulder on these screws made setting up a small pivot axle a breeze. They seated perfectly in the bore without any wobble. This 25-pack should last me through several projects.
