Gearwrench 80428D Hex Bit Socket 3/8 in Drive 7 Mm

Product Description

The GEARWRENCH 80428D is a hand hex bit socket designed for driving 7 mm hex fasteners with a standard 3/8 inch square drive ratchet or breaker bar. The socket measures 1-3/16 inches overall length with a 1.181 inch bit length, giving the tool enough engagement depth for typical hex-head cap screws, set screws, and socket-head fasteners found in mechanical assemblies. Constructed from steel with a chrome finish, this bit socket is suited for professional hand-tool use in automotive, HVAC equipment panels, plumbing fixture work, and general mechanical service. Electricians, plumbers, HVAC technicians, and general mechanics reach for this type of socket when working in confined spaces where a standard hex key cannot generate adequate torque.

This hex bit socket is appropriate for residential and light commercial service work where 7 mm hex fasteners appear on equipment covers, valve bodies, bracket hardware, and machinery components. The 3/8 inch drive size is the standard intermediate drive found on most technician ratchet sets, making this socket immediately compatible with existing drive tool inventory without requiring an adapter. It is packaged individually and sold as a single unit.

Key Features

• 7 mm hex bit fits hex-head cap screws and socket-head fasteners common in mechanical and equipment service
• 3/8 inch square drive interfaces directly with standard ratchets, extensions, and torque wrenches
• 1.181 inch bit length provides sufficient fastener engagement depth to reduce cam-out risk
• Steel construction with chrome finish resists surface corrosion in typical shop environments
• Meets ANSI and ASME standards for hand socket tools
• Compact 1-3/16 inch overall length suits work in tighter clearances

Compatibility

Designed as a standard 3/8 inch drive hex bit socket for use with 3/8 inch drive ratchets, extensions, and torque wrenches across professional and trade hand-tool applications.

Installation Notes

Install and remove using a 3/8 inch drive ratchet, breaker bar, or torque wrench. Ensure the fastener hex recess is clean and free of debris before seating the bit to prevent premature wear. De-energize or shut off any equipment before loosening or tightening fasteners on live mechanical assemblies. Follow applicable equipment manufacturer torque specifications and relevant service codes when reassembling components.
