براغي رأس سوكيت 1/2-13 × 3/4 بوصة | محرك سوكيت سداسي | حبيبات نايلون | ملولب بالكامل | فولاذ سبائكي أسود حراري (50/عبوة)

The black oxide finish on these screws looks clean and professional, and the nylon pellet locks them in place perfectly on my milling machine setup. They threaded smoothly into the tapped holes without any binding.

I needed some sturdy fasteners for a jig I’m building, and these 1/2-13 x 3/4" socket cap screws fit perfectly—the hex socket drive made tightening them a breeze. The nylon pellet is a nice touch for locking them in place without thread locker.

The black oxide finish on these screws resists rust way better than I expected for the price. Used them to secure a jig on my milling table, and the hex socket drive made installation a breeze.
