Gearwrench 84143 Impact Socket 1/4 in Drive 8mm

Product Description

The GEARWRENCH 84143 is a 6-point metric impact socket designed for use with 1/4 inch square drive impact wrenches and ratchets. Built from chromium-molybdenum steel and finished in manganese phosphate, it delivers the toughness and corrosion resistance required for repeated impact use. The hex drive profile and 6-point geometry reduce fastener rounding through off-corner loading, which contacts flat sides rather than corners under torque. At 1.968 inches overall length, it fits into tight spaces common in mechanical and electrical panel work. High-visibility laser-etched size markings and secondary hard-stamped markings keep identification fast even in low-light shop conditions. This socket meets ASME B107.33M standards and carries a limited lifetime warranty.

The 84143 is suited for automotive, mechanical, HVAC, and general trade applications where an 8mm fastener and a 1/4 inch drive impact tool are in use. Its compact overall length makes it practical for close-clearance fastening on equipment panels, motor mounts, and bracket hardware. Trade professionals including HVAC technicians, electricians, and plumbers will find this socket useful for the small-fastener work common in residential and light commercial service calls.
