Gearwrench 80424 Hex Bit Socket 3/8 in Drive 3 Mm

Product Description

The GEARWRENCH 80424 is a 3/8 inch drive hex bit socket designed for driving hex fasteners in mechanical, automotive, and industrial service applications. Built from steel with a chrome finish, it accepts a 3 mm hex bit and delivers a bit length of 1.181 inches with an overall length of 1-55/64 inches. The compact profile makes it well-suited for fasteners in tight spaces where a standard hex key or T-handle cannot generate adequate torque. Licensed mechanics, automotive technicians, and maintenance professionals reach for this socket when working on assemblies that use metric hex-head cap screws or socket head fasteners.

This hex bit socket is used across a wide range of service scenarios including automotive drivetrain work, HVAC equipment fastener service, machinery maintenance, and general mechanical assembly. The 3/8 inch drive connection pairs with standard 3/8 inch ratchets, extensions, and torque wrenches, making it a direct fit into any 3/8 inch drive tool set. The 3 mm hex size targets small-to-medium metric hex fasteners common in imported equipment, appliance assemblies, and light industrial machinery.

Key Features

• 3/8 inch drive connection compatible with standard ratchets, extensions, and torque wrenches
• 3 mm hex bit size for metric hex-head and socket-head fasteners
• 1.181 inch bit length provides solid fastener engagement
• 1-55/64 inch overall length suits confined service areas
• Steel construction with chrome finish for corrosion resistance and durability
• Meets ANSI and ASME standards for dimensional accuracy and performance

Compatibility

Designed as a standard 3/8 inch drive hex bit socket for use with any 3/8 inch drive ratchet, breaker bar, extension, or torque wrench requiring a 3 mm hex bit interface.

Installation Notes

Seat the socket fully onto the 3/8 inch drive ratchet or extension before applying torque to prevent drive slippage. Verify the hex bit is fully engaged in the fastener recess before turning to avoid rounding the fastener head. Do not use impact drivers with this hand-rated socket unless the socket is rated for impact service. Inspect the socket and drive square for wear or deformation before each use.
