HOLO-KROME 33036 براغي مقبس سداسي بنقطة كوب #6-40 × 1/4 بوصة | فولاذ سبائكي مع أكسيد أسود حراري (100/عبوة)

Had to swap out a stripped screw on a motor mount and these little guys torqued in perfectly with my hex key. The thermal black oxide finish gives them a nice grip in the threads, and the cup point seated firmly without budging. A full pack of 100 means I'm set for the next few projects too.

The cup point on these set screws bites into the shaft perfectly and holds tight—no slipping at all during assembly. They threaded cleanly into the tapped holes without any binding.

The hex socket drive made it easy to torque these down in a tight spot without stripping, and all 100 screws in the pack had clean threads. They seated flush and held my collar in place on the first try.
