The shoulder on these is so precisely ground that my axle spins without any wobble at all, even under load. I’ve bought cheaper screws before and always had to shim them, but these fit true from the first try.

Used one as a pivot on a custom jig; the precision-ground shoulder makes rotation feel incredibly smooth and consistent. They're a bit pricier than standard bolts, but for repetitive motion, they're well worth it. Fit perfectly in a standard hex key socket.

The hex socket drive fits a standard Allen key perfectly, and the precision-ground shoulder slides through my jig with zero wobble. These are going to make solid pivot points for the cabinet doors I'm building, and the stainless finish looks clean against the wood.
