彈簧銷 7/16" X 3" | 開槽 | 鋼鍍鋅 (300個/包)

These 3-inch spring pins slid right into the tractor hitch linkage with no binding, and the zinc plating feels solid against rust. They hold the components tight even after a day of bumpy field work. Just what I needed for that shear load application.

The zinc plating on these pins is uniform and slick, so they drive into the holes without galling or binding. A full box of 300 means I’ve got plenty left over for the next few jobs, and they hold under vibration exactly as promised.

I’ve been hammering these in all morning to hold a jig together under constant vibration, and so far not a single one has walked loose. The zinc coating is smooth enough that they drive in clean without binding. For a 300-pack, this is exactly the kind of stock I like to keep on the shelf.
