Product description

The upper pin is a specialized structural fastener designed for the high-pivot points of Snap-On tire changers. This pin typically connects the upper sections of the swing arm or tower assembly, allowing for the precise articulation needed to position the tool head over the wheel rim. Built to withstand significant vertical and lateral stresses, this pin is manufactured from hardened alloy steel to ensure it does not deform under the leverage applied during the tire mounting process. Its smooth, finished surface allows for easy lubrication and consistent movement, which is essential for operator ease of use and machine accuracy. Replacing a worn or bent upper pin is crucial for maintaining the precise vertical alignment of the mounting head.
