Upgrade & Restore Your Tire Changer's Mechanical Rigidity

The 1"/4" Whiz Lock Screw is a high-tensile structural fastener designed to clamp and secure cylinder plates, tower bases, and mechanical brackets on professional tire changers.

Worn, stretched, or cross-threaded bolts cannot hold the proper clamping force, which leads to mechanical shift and misalignment. Replacing them restores rigid mechanical alignment.

Machine Location:

This fastener is used in the cylinder mounting plates, vertical towers, or bead breaker arm pivot structures.
