براغي ذات رأس مقبس 3/8-16 × 5/8" | رأس مسطح بمحرك سداسي | حبيبات نايلون | ملولبة بالكامل | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

The nylon pellet in the threads is a nice touch—they snug up against the mating piece without galling, which is exactly what I need for a jig that gets taken apart weekly. All 100 of them have clean, consistent hex sockets and the black oxide finish looks sharp.

Just finished a small tooling jig and these flat head screws seated perfectly flush. The hex socket drive made installation quick, and the nylon pellet holds firm under vibration.

The black oxide finish looks great on my jig build and should hold up fine with all the clamping I do. The hex socket drive seated cleanly every time, and the flat head sits flush without any wobble. Pack of a hundred means I won’t be reordering these anytime soon, which is exactly what I wanted.
