This precision-machined screw works in conjunction with a ring gear to provide the high mechanical advantage necessary to securely clamp wheel rims and rotate them through the mounting process. Made from hardened steel to resist the abrasive wear and high pressure associated with worm drive systems, the ST0019184 is built for the long haul in demanding service environments. Its smooth, consistent thread geometry ensures that the clamping force is applied evenly, preventing wheel slippage and potential damage to customer rims. As a critical point of power delivery, a worn worm screw can lead to inaccurate operation and increased maintenance costs; replacing it with this genuine Snap-On part restores the precision and reliability of your tire service platform.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardened Steel Construction:\u003c\/strong\u003e Engineered to withstand the extreme friction and pressure of high-torque worm drives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise Thread Geometry:\u003c\/strong\u003e Ensures smooth engagement and consistent power delivery to the clamping system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Mechanical Advantage:\u003c\/strong\u003e Provides the necessary force to securely hold heavy wheels during service.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Durability:\u003c\/strong\u003e Designed to meet the rigorous performance standards of Snap-On and John Bean machinery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Replacement:\u003c\/strong\u003e Guaranteed fit for the internal chuck drive assemblies of compatible tire changers.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Snap-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e ST0019184\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Worm Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Hardened Steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eSnap-On ST0019184, John Bean ST0019184, Hofmann ST0019184\u003c\/p\u003e\u003cp\u003eYou will receive the same product or an OEM-Equivalent that meets the highest standard of the OEM with warranty that will be a direct-fit.
