Gearwrench 84640 Hex Bit Socket 1/2 in Drive 3/4 in Hex

Product Description

The GEARWRENCH 84640 is a hex bit socket designed for use with 1/2 inch drive ratchets, breaker bars, and torque wrenches. It accepts a 3/4 inch hex bit and delivers direct, high-torque fastener engagement on hex-head bolts and socket head cap screws. The bit length measures 3/4 inches, and the overall length is 3.07 inches. Built from steel to ASME B107.33 standards, this socket suits demanding trade applications including mechanical, HVAC equipment service, and industrial assembly work where consistent hex drive performance is required.

This hex bit socket is suited for residential and commercial mechanical service environments. It is commonly used by HVAC technicians, plumbers, and general maintenance professionals who encounter hex-head fasteners on equipment panels, flanges, valve assemblies, and structural hardware. The 1/2 inch drive interface is standard across professional-grade drive sets, making this socket a direct fit on most journeyman and service truck tool kits without adapter requirements.

Installation Notes

This socket is installed and removed by hand on any 1/2 inch square drive tool. Ensure the drive tool and socket are fully engaged before applying torque to prevent rounding of the fastener or socket damage. Confirm the fastener hex size matches the 3/4 inch bit before use. No special codes apply, but follow equipment manufacturer service procedures when accessing fasteners on pressurized or energized systems.
