HOLO-KROME 08142 براغي كتف مقبس 3/4 × 4 بوصة | رأس مقبس | محرك مقبس | فولاذ سبائكي أكسيد أسود حراري (10 / عبوة)

I've been using these as pivot pins on a custom indexing fixture, and the precision ground shoulder runs true with no wobble. The hex drive makes installation straightforward with a standard Allen key. They feel solid and the black oxide finish should resist light rust in my shop.

I needed a shoulder screw for a jig I’m building, and the hex socket drive made installation with an Allen key effortless—way easier than using a slotted head. The black oxide finish also feels tough and doesn’t show shop grime.

The hex socket drive grabbed onto my allen wrench perfectly, no slipping at all. I used a pair as pivot pins for a small jig and the precision shoulder ran smooth and true. Solid little fasteners for the price.
