Product Overview
The US PRO Tools 3959 is a heavy-duty, industrial-grade 1-inch drive 90mm 6-point impact socket engineered for extreme high-torque commercial and heavy equipment maintenance. Built specifically to handle oversized fasteners on heavy commercial trucks, agricultural machinery, construction plant equipment, and industrial applications, this socket transmits massive rotational force without flexing, cracking, or rounding fastener corners.
Key Features & Specifications
-
Massive 90mm Metric Size: Sized precisely for large-scale commercial axle nuts, suspension components, and heavy structural fasteners.
-
Heavy-Duty 1-Inch Square Drive: Designed for pairing with high-output 1-inch pneumatic, electric, or hydraulic impact wrenches and heavy breaker bars.
