براغي رأس مقبس 1/2-20 × 1-1/2" | محرك مقبس سداسي | رقعة نايلون | ملولبة بالكامل | فولاذ سبيكة مع أسود حراري (50 / عبوة)

I needed some heavy-duty fasteners for a jig I was building, and these 1/2-20 socket cap screws with the nylon patch held tight without any loosening. The hex drive made installing them a breeze with just an allen wrench.

The black oxide finish on these is exactly what I needed for the jigs I’m building—looks clean and hasn’t shown a hint of rust after a week in my damp garage. They’re fully threaded which made alignment with the nylon patch easy, and every one of the 50 drove in smooth with no stripping. Definitely

The nylon patch is a game-changer for my jigs—holds tight without needing lock washers. They threaded smoothly into my tooling plate with zero binding. These 1/2-20 cap screws are exactly what I needed for precision assemblies.
