براغي غطاء مقبس #1-64 × 1 بوصة | محرك مقبس سداسي برأس مسطح | خيط جزئي | فولاذ سبائك أسود حراري (200 / عبوة)

The black oxide finish on these #1-64 screws gives them a sturdy, professional look and they fit perfectly into my precision assembly work. They thread smoothly into the tapped holes without any binding, which saved me time on a small tooling project.

I needed some small screws for a jig I’m building, and these #1-64 x 1" flat heads fit perfectly in the countersunk holes. The hex socket drive made it easy to tighten them with a tiny Allen key without stripping.

The black oxide finish on these #1-64 screws is consistent across the whole pack, and the hex socket drive grabbed perfectly with my driver—no stripping or wobble. They seated flush in my jig holes like they were machined for them, and 200 pieces means I’ve got plenty left for future tooling fixes.
