Klein Tools 66010 Deep Impact Socket Set 6 Pc 12 Point

Product Description

The KLEIN TOOLS 66010 is a 6-piece deep impact socket set designed for use with 1/2-inch drive impact wrenches and rattle guns. Built from steel and engineered to the ASME B107.2 standard, these 12-point deep sockets handle the high-torque demands common in electrical, mechanical, and construction trades. The set spans six sizes ranging from 3/8 inch to 1-1/8 inch, with each socket pairing an imperial outer size to a corresponding imperial drive engagement. The set arrives in a blow-mold plastic carrying case that keeps sockets organized on the job site and in the service van.

This set is suited for residential and commercial trade work where deep reach is required to seat fully onto fasteners with extended threads or stacked hardware. Electricians, HVAC technicians, and general contractors will find these sockets useful for panel work, equipment mounting, conduit fittings, and structural fastener applications. The 12-point design provides multiple engagement positions, which is useful in tight spaces where swing arc is limited.

Compatibility

Designed for use with 1/2-inch drive impact wrenches, breaker bars, and ratchets. Socket sizes included are: 1-1/8 x 15/16, 1 x 13/16, 7/8 x 11/16, 3/4 x 9/16, 5/8 x 7/16, and 1/2 x 3/8 inches.

Installation Notes

Impact sockets should be used only with impact-rated drive tools — never substitute chrome hand-tool sockets with an impact wrench, as they are not rated for torsional shock loads. Confirm the socket is fully seated on the fastener before applying torque to avoid rounding. Inspect sockets periodically for cracks, deformation, or worn drive squares and remove any damaged sockets from service immediately.
