براغي تثبيت مقبس بنقطة كوب مخددة M12 × 35 مم | فولاذ سبائكي (100/عبوة)

The knurled cup point grips the shaft securely without slipping, even after a few rounds of adjustment. Alloy steel feels solid and the hex drive handled the tight spots under my workbench just fine.

The hex socket drive made torquing these down in a cramped machine frame a breeze, and the knurled cup point bit into the shaft without slipping. All 100 pieces arrived clean and uniformly threaded, which is more than I can say for other bulk packs I've tried.

Installed these on a conveyor guide rail where I needed precise positioning without stripping the threads. The knurled cup point really digs in and holds tight, even under vibration.
