براغي رأس مقبس #10-32 × 1 بوصة | محرك سداسي | رقعة نايلون | ملولبة بالكامل | فولاذ سبائكي مؤكسد أسود حراري (200 / عبوة)

The nylon patch on these is a lifesaver—no more fighting with lock washers on my jig fixtures. They seat cleanly with a hex key and the black oxide finish actually feels smooth, not chalky. Fastened down a whole tooling plate in minutes without a single stripped thread.

These are exactly what I needed for a jig I was building, and the hex socket drive made installation in tight spots a breeze. The black oxide finish looks clean and professional too.

The nylon patch is perfect for keeping these screws from backing out in my milling table, and the black oxide finish looks clean. They threaded into tapped holes without any issue, even on the first try.
