Proto J5408MH Hand Socket 8mm 6-point 1/2 Drive

Product Description

The PROTO J5408MH is a 6-point hand socket designed for 1/2 inch drive ratchets and breaker bars. Built from alloy steel with a chrome-plated finish, it accepts 8 mm fasteners and measures 1-19/64 inches in overall length at standard depth. The 6-point geometry contacts fastener flats rather than corners, reducing rounding risk on worn or tight hardware. This socket is suited for mechanical, maintenance, and assembly work wherever a 1/2 inch drive toolset is in use. Licensed trades and general mechanics reach for this size frequently on metric fastener applications across automotive, HVAC equipment panels, and light industrial machinery.

The J5408MH fits into standard 1/2 inch drive socket sets and is appropriate for residential service calls, commercial maintenance environments, and shop use. Its standard-length profile works in most open-access situations. The chrome finish resists corrosion and simplifies cleanup after use in greasy or oily service conditions. This socket is sold individually, making it a practical replacement for a single worn or missing size in an existing set.

Key Features

• 8 mm socket size fits common metric fasteners in automotive and mechanical applications
• 6-point contact geometry reduces fastener rounding on stubborn or corroded hardware
• 1/2 inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Alloy steel construction meets ASME B107.5M standards for hand socket tools
• Chrome-plated finish resists corrosion and simplifies cleaning
• Standard length at 1-19/64 inches overall suits most open-access fastener locations

Compatibility

Designed for use with 1/2 inch drive ratchets, breaker bars, extensions, and torque wrenches accepting standard square drive sockets.

Installation Notes

Install and remove using a 1/2 inch drive ratchet, breaker bar, or torque wrench. Ensure the socket is fully seated on the fastener before applying force to avoid slippage. This socket is not tether capable and should not be used in overhead or elevated work where drop hazards exist without additional retention measures. Inspect the socket for cracks or wear before each use and replace if deformation is observed.
