Proto J5220HS 5/8 Inch 6-point 3/8 Drive Hand Socket

Product Description

The PROTO J5220HS is a 6-point hand socket designed for professional-grade fastener work in mechanical, industrial, and maintenance applications. Built from alloy steel with a chrome finish, this socket fits a 5/8 inch fastener and accepts a 3/8 inch drive. The low-profile body measures 15/16 inches in overall length, making it suited for tight-clearance situations where a standard-depth socket will not seat. At 0.09 pounds, it is a lightweight piece that carries the durability expected from alloy steel construction. Licensed tradespeople and maintenance technicians rely on this socket for everyday wrench and ratchet work.

The J5220HS is appropriate for residential and commercial maintenance tasks, automotive service, HVAC equipment servicing, and general mechanical repair where a 3/8 inch drive ratchet or extension is in use. The 6-point contact geometry distributes torque evenly across fastener flats, reducing the risk of rounding on hex-head fasteners under load. The low-profile length is particularly useful when working in recessed or obstructed bolt locations with limited axial clearance.

Key Features

• 5/8 inch socket size fits standard hex-head fasteners of that dimension
• 3/8 inch square drive accepts standard ratchets, extensions, and torque wrenches
• 6-point contact design reduces fastener rounding under load
• Low-profile overall length of 15/16 inches for tight-clearance access
• Alloy steel construction with chrome finish for corrosion resistance and durability
• Not tether capable — standard use in non-drop-zone environments

Compatibility

Designed as an OEM-style hand socket compatible with standard 3/8 inch drive ratchets, extensions, and torque wrenches accepting 6-point 5/8 inch sockets.

Installation Notes

This socket is installed and removed by hand using a compatible 3/8 inch drive tool. Ensure the drive tool is rated for the torque being applied before use. Inspect the socket and fastener for wear or damage before each use to prevent slippage. Chrome-plated sockets are intended for hand-tool use and should not be used with impact drivers.
