Customer Reviews (4.8 / 5 · 5 reviews)

Chloe ★★★★★

The precision-ground shoulder is spot on for a pivot application I'm working on, and the black oxide finish looks and feels solid out of the box. Fit in the bore was snug without any binding, just how I wanted it.

Sofia ★★★★★

Finally found these at the exact dimensions I needed for a heavy-duty indexing fixture—the precision-ground shoulder fits the bearing bore perfectly. They’re pricey for a pack of 25, but the black oxide finish looks clean and they’ve held up through a week of 8-hour shifts without a hitch.

Carter ★★★★★

The precision ground shoulder makes these work beautifully as a pivot pin—no wobble or slop once torqued down. The black oxide finish looks sharp and hasn't chipped during assembly. I've already ordered another pack for the next project.
