HOLO-KROME 08064 مسامير كتف مقبس 3/8" × 4" | رأس مقبس | محرك مقبس | سبائك فولاذ أكسيد أسود حراري (25/عبوة)

The precision ground shoulder on these screws makes them work perfectly as a pivot point in my jig, and the hex drive seated the wrench without slipping. They feel solid and exactly the quality I needed for this project.

I was a little worried these would be too tight for my build, but the hex socket drive made installation smooth, and the thermal black oxide finish gives them a nice, durable look. They've worked perfectly as pivot points on a jig I'm building.

Used one of these as a pivot pin in a jig I built, and the precision ground shoulder made for a buttery-smooth rotating action. The thermal black oxide finish also seems tough—no signs of wear after a weekend of heavy use. Really solid screws.
