Gearwrench 84946 Impact Thin Wall Socket Set 3pc 1/2in Drive

Product Description

The GEARWRENCH 84946 is a 3-piece metric impact thin wall socket set built for professional technicians who need reliable torque transfer in tight clearance applications. The set covers 17mm, 19mm, and 21mm sizes — a range that handles common fastener sizes found in suspension, drivetrain, and general mechanical work. Each socket is machined from alloy steel with a manganese phosphate finish that resists corrosion and reduces glare in low-light shop conditions. The 6-point contact geometry grips fastener flats firmly, minimizing rounding under high-torque impact use. All three sockets are rated to ASME standards and carry a lifetime warranty.

This set is designed for use with 1/2 inch drive impact wrenches and ratchets in automotive, fleet, and industrial maintenance environments. The thin wall profile is particularly useful on wheel hub fasteners, strut components, and other locations where a standard-wall socket will not clear surrounding hardware. Professional mechanics, fleet technicians, and heavy equipment service pros will find this set covers the fastener sizes most commonly encountered in metric drivetrain and chassis work. Sockets store in an included blow molded case for organized transport and jobsite use.

Key Features

• Thin wall design clears tight fastener recesses where standard sockets will not fit
• 6-point socket geometry reduces fastener rounding under high-torque impact loads
• Alloy steel construction rated for impact driver use
• Manganese phosphate finish resists corrosion and reduces surface glare
• Meets ASME standards for socket dimensions and performance
• Blow molded case keeps all three sockets organized and protected

Compatibility

Designed for use with 1/2 inch drive impact wrenches, air ratchets, and hand ratchets requiring metric thin wall sockets in the 17mm to 21mm range.

Installation Notes

Impact sockets should only be used with impact-rated drive tools — never substitute hand-tool chrome sockets on an impact wrench, as they can fracture under shock loads. Confirm the socket is fully seated on the fastener before applying torque. Inspect sockets periodically for cracks, deformation, or worn drive squares and remove any damaged sockets from service immediately.
