HOLO-KROME 32162 براغي مقبس نقطة كوب 5/16-18 × 2 بوصة | فولاذ سبائكي مع أكسيد أسود حراري (50 / عبوة)

Just got these set screws in for a motor mount repair, and the hex socket took the torque without stripping. Exactly the length and thread pitch I needed for a snug fit on the shaft.

The cup point really grips the shaft firmly once you torque them down, and the black oxide finish makes them look clean and professional. I've used a dozen so far on a gear alignment job and every one threaded smoothly without any galling.

These screws fit perfectly into the tapped holes I'm working with, and the hex drive made installation straightforward. I was pleasantly surprised by how consistent the threading is across all fifty pieces.
