Product description

The 1/2-13 Lock Jam Nut is a specialized low-profile fastener used to secure adjustments on Coats tire changers. It is typically used in conjunction with a standard nut to "jam" or lock a setting in place, such as on a threaded rod or pivot shaft. The 1/2-inch size and 13 TPI (Threads Per Inch) configuration matches the heavy-duty mounting studs found in bead loosener assemblies and tabletop clamping systems. By preventing the primary fastener from turning, this jam nut ensures that your machine's mechanical limits remain accurate over thousands of cycles. It is a necessary component for any shop performing regular maintenance or repairs on their rim clamp equipment.
