براغي رأس كاب 7/16-14 × 7/8 بوصة | محرك مقبس سداسي | صناعة أمريكية | فولاذ سبائكي أكسيد أسود حراري (400 / عبوة)

The black oxide finish on these is flawless, no chipping or uneven spots after I torqued them down on a fixture. They’re consistently sized across the whole box of 400, which saves me so much sorting time for production runs.

I needed a solid batch for a jig I’m building, and the hex socket drive made tightening them into tight spots much easier than I expected. Each screw threaded cleanly without any burs, and the 400-count package is honestly more than I’ll use for a while, but the price per piece was worth it.

The black oxide finish on these screws looks professional and resists wear well on my jig fixtures. Threads are cleanly cut and the hex drive engages without any wobble. Exactly what I needed for precise assembly work.
