Key Features
Budd Wheel Compatibility: Specifically designed to fit 20mm inner budd-style square fasteners common in commercial vehicle wheel assemblies.
GP High Torque Drive: Innovative design redirects pressure away from fastener corners to the thicker socket walls, increasing strength and durability for high-torque impact use.
Chrome-Molybdenum Construction: Manufactured from premium CR-MO alloy steel and precision heat-treated for a professional balance of strength and impact resistance.
Compact Thin-Wall Design: Engineered with reduced wall thickness to provide easier access to fasteners in restricted or cramped areas without sacrificing tool integrity.
Corrosion Resistance: Finished with a professional black oxide coating to protect the steel from rust and environmental wear in demanding shop or field conditions.
