براغي رأس أسطوانية مقاس #2-56 × 1/4 بوصة | محرك سداسي | رقعة نايلون | ملولبة بالكامل | فولاذ سبائكي مؤكسد حراريًا أسود (100/عبوة)

The nylon patch saved me from using threadlocker on these small screws, which is a huge time-saver for jig assembly. They fit perfectly into the hex drive without stripping, and the black oxide finish feels sturdy.

I've been burned by tiny screws that strip the moment you breathe on them, but these #2-56s with the hex socket drive bit in cleanly and hold their torque. The nylon patch is a nice touch—they haven't backed out once on my jig, even under vibration.

The black oxide finish is really nice and clean, and they held perfectly in my precision drilling jig without any wobble. For the price, getting 100 of these little guys with the nylon patch already applied is a solid deal.
