براغي رأس كبس بمقبس سداسي 5/16-18 × 2 بوصة | مشبك نايلون | خيط جزئي | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

The nylon patch on these is a huge time-saver—no need to mess with threadlocker during assembly. They seated perfectly in my jig fixtures and the black oxide finish gives them a clean, professional look.

The threads cut clean and the thermal black oxide finish looks even across all 100 pieces, no bare spots or chips that I could find after sorting through them. I’ve used them to bolt down a jig on my mill table and they seated firmly without any galling, which is exactly what I hoped for.

The nylon patch on these is a nice touch—keeps them from backing out under vibration without needing a separate lock washer. I used them to rebuild a small press jig, and the black oxide finish held up well to a little cutting oil.
