HOLO-KROME 32132 براغي ضبط رأس كب 1/4-20 × 1-1/2" نقطة كوب | فولاذ سبائكي أكسيد أسود حراري (100 / عبوة)

Opened the box and the black oxide finish looks sharp right out of the package. The 1/4-20 threads cut cleanly into my steel hub, and the cup point grips the shaft firmly without slipping under load.

Installed these on a garage shelving bracket and the hex socket drive made tightening them a breeze. The cup point really digs in and holds firm, even with some vibration from my tools.

The thermal black oxide finish has held up well through a few assembly and disassembly cycles without any wear. These cup point screws were exactly what I needed to secure a shaft collar in place.
