HOLO-KROME 32134 براغي مقبس بنقطة كوب مقاس 1/4-20 × 1-3/4 بوصة | فولاذ سبائكي مع أكسيد أسود حراري (50 / عبوة)

The black oxide finish on these screws looks clean and professional, and they seated perfectly in the threaded holes I prepared. The hex socket drive made installation straightforward with no stripping.

These hold a pulley on a motor shaft like a champ, and the cup point really digs in without stripping. The black oxide finish makes them easy to see against the steel. Exactly what I needed for a solid, repeatable clamp.

Used a handful of these to secure a sprocket on a small custom build, and the hex socket engagement felt precise with no stripping. The thermal black oxide finish looks clean and seems like it’ll hold up well against light rust in my shop.
