براغي HOLO-KROME 86150 #4-40 × 3/16 بوصة برأس أسطواني | محرك سداسي | فولاذ سبائكي مؤكسد حراريًا أسود (100 / عبوة)

The hex socket drive on these little screws fit my driver perfectly—no cam-out issues even on a tight jig. They're exactly the right size for small machinery repairs I've been tackling.

I needed a handful of these for a small fixture repair, and the hex socket drive made installation effortless in a tight spot. The black oxide finish seems tough and even across all 100 screws.

The threads cut cleanly and seated perfectly in my jig fixture without any binding, which is exactly what I needed for a tight assembly. The black oxide finish looks uniform across all 100 pieces, so these should hold up well against minor moisture in my shop.
