Proto J47055M 5mm 6-point 1/4 Drive Hand Socket

Product Description

The PROTO J47055M is a 5 mm, 6-point hand socket designed for precise fastener engagement in professional hand tool applications. Built on a 1/4-inch drive, it features a standard-length profile and a chrome-plated finish that resists corrosion and simplifies cleanup. The 6-point geometry reduces fastener rounding under load compared to 12-point designs, making it a reliable choice for production, maintenance, and repair work. At 0.02 pounds, it is a lightweight addition to any metric socket set used by mechanics, industrial technicians, and trade professionals who require accurate torque application on small fasteners.

This socket is suited for use in automotive, HVAC equipment panels, electrical enclosures, and light industrial assemblies where 5 mm metric fasteners are common. The standard-length design allows access in typical open-clearance applications. It is appropriate for both bench work and field service where a 1/4-inch drive ratchet or extension is in use.

Key Features

• 5 mm socket size for metric fastener applications
• 6-point contact geometry minimizes fastener rounding under load
• 1/4-inch drive compatible with standard ratchets and extensions
• Chrome-plated finish resists corrosion and cleans easily
• Standard-length profile for general open-clearance access
• Lightweight at 0.02 pounds for easy handling and portability

Compatibility

Designed as a standard 1/4-inch drive metric hand socket compatible with 1/4-inch drive ratchets, extensions, and adapters used in professional hand tool sets.

Installation Notes

This socket is installed and removed by hand using a 1/4-inch drive ratchet or extension. Ensure the socket is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Inspect the socket for wear or cracking before each use. No power tools should be used with a hand-rated socket unless the socket is explicitly rated for impact use.
