براغي ذات رأس أسطواني 3/8-24 × 3/4 بوصة | محرك سداسي برأس مسطح | حبيبات نايلون | ملولبة بالكامل | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

I needed some flat head screws for a jig I’m building, and these fit perfectly with my countersunk holes—the hex drive made tightening them down a breeze. The nylon pellet is a nice touch for keeping them locked in place.

The black oxide finish on these is exactly what I wanted for a jig I’m building—it’s uniform and doesn’t leave that greasy residue some coated screws have. The nylon pellet locks them in place nicely, and all 100 threaded clean without a single hiccup.

Was setting up a new drill jig and needed these exact 3/8-24 flat heads. The nylon pellet really locks them in place without needing threadlocker, and the black oxide coating feels durable.
