Customer Reviews (4.8 / 5 · 5 reviews)

Thomas J. ★★★★★

The hex socket drive made torquing these down a breeze, and the 18/8 stainless finish looks clean on the pivot assembly I built. They slid into the bore with zero play, exactly what you want from a precision-ground shoulder.

George K. ★★★★★

The shoulder on these is ground so precisely that my axle spins without any wobble, even under load. Took a chance on the 18/8 stainless for a pivot point and it’s held up perfectly through a month of daily use.

Ryan ★★★★★

I needed a smooth bearing surface for a small mechanical pivot, and the shoulder on these screws is machined perfectly—no wobble at all. The hex drive seated firmly without stripping, which I really appreciate.
