براغي رأس كبس 3/4-10 × 2-3/4" | محرك سداسي | حبيبات نايلون | كامل الخيوط | فولاذ سبائك بأكسيد أسود حراري (25/عبوة)

Installed these into a jig I’m building for a project, and the black oxide finish held up perfectly against a little moisture. The threads cut cleanly into the steel plate without any binding. Exactly what I needed for precision work.

The hex socket drive grabbed firmly on my ratchet without any stripping, and the nylon pellet locking feature was a nice bonus. These are working out perfectly for building my jig, and the black oxide finish looks sleek against the steel.

The thermal black oxide finish hasn’t shown a single speck of rust after a week in my damp shop, and the nylon pellet locks them in place noticeably well. These fully threaded 3/4-10s seated perfectly in my jig fixture, no wobble at all.
