Gearwrench 84387N Impact Socket 3/8 in Drive 15/16 in 6-pt

Product Description

The GEARWRENCH 84387N is a 6-point impact socket designed for heavy-duty fastener removal and installation in professional trade and shop environments. Built from chromium-molybdenum steel with a black oxide finish, it accepts a 3/8 inch drive and fits a 15/16 inch SAE hex fastener. The overall length is 1.181 inches, placing it in the standard-length category. High-visibility laser-etched markings and secondary hard-stamped size markings allow fast size identification when working out of a toolbox or impact kit. The off-corner loading design reduces fastener rounding under high-torque impact tool use. This socket meets ASME B107.2 standards and carries a lifetime warranty.

This socket is suited for automotive, HVAC, plumbing, and general mechanical service work where a 3/8 inch drive impact wrench or ratchet is the tool of choice. The 15/16 inch SAE size is commonly encountered on bolts, nuts, and fittings across residential and light commercial mechanical systems. Standard length makes it practical for open-access fastener work. It is a single-piece, non-insulated, non-sparking-rated socket intended for use by mechanics, service technicians, and tradespeople requiring a reliable impact-rated hand tool socket.

Key Features

• Chromium-molybdenum steel construction rated for impact tool use
• 6-point drive geometry minimizes fastener rounding under torque
• Off-corner loading design reduces contact stress on fastener flats
• High-visibility laser-etched markings plus secondary hard-stamped size identification

• Meets ASME B107.2 standard; backed by a lifetime warranty

Compatibility

Designed for use with 3/8 inch drive impact wrenches, air ratchets, and hand ratchets requiring a standard-length 15/16 inch SAE 6-point impact socket.

Installation Notes

Install and remove this socket with the drive tool fully powered down or the air supply disconnected before changing sockets. Ensure the socket is fully seated on the drive anvil and the retaining pin or ring is engaged before applying torque. Do not use impact sockets on torque-sensitive fasteners without a calibrated torque wrench adapter. This socket is not rated for insulated or non-sparking applications.
