Boston Gear 7/16" Bore Shaft Collar With Set Screw - New Open Box (Light Rust)

Alright, so this is a Boston Gear shaft collar with a 7/16-inch bore, the kind with a set screw to lock it in place.

It's a new open box item, meaning it's never been used, but the seller notes it has some light surface rust from just sitting around.

Honestly, for a chunk of metal like this, that's nothing a little wire brush can't fix.

Boston Gear makes solid industrial stuff, and this one's made in the USA.

If you need a specific size, check out the store—they mention having many other sizes available.

A simple, sturdy component for your project.
