براغي كتف مقبس M12 × 100 مم | رأس مقبس | محرك مقبس | فولاذ سبائكي (25 / عبوة)

The precision-ground shoulder on these screws is noticeably smooth, making them ideal for a bearing pivot I built. The hex socket drive holds the wrench well without slipping during tightening.

Used a few of these as axles for a small machine I built, and the ground shoulder really did make for a smooth bearing surface. The hex drive seated nicely without stripping, which I appreciate. Solid fit for the price.

The shoulder on these is dead-on straight, which made dialing in the axle alignment for my build a lot easier than I expected. Only gripe is the packaging could be sturdier, but all 25 arrived without a scratch and the hex sockets were clean.
