Proto J5417MH 17mm 6-point 1/2 Drive Hand Socket

Product Description

The PROTO J5417MH is a 17 mm, 6-point hand socket designed for 1/2 inch drive ratchets and breaker bars. Built from alloy steel with a chrome-plated finish, it delivers corrosion resistance and a clean look that holds up in shop and field use. The standard-length body measures 1.5 inches overall, making it a straightforward fit for most fastener access situations. Manufactured to ASME B107.5 standards, this socket meets the dimensional and performance requirements that licensed mechanics and trade professionals expect from a production-grade hand tool.

This socket is suited for automotive, heavy equipment, HVAC, plumbing, and general mechanical service work where a 17 mm fastener size is common. The 6-point contact pattern reduces the risk of rounding hex fasteners compared to 12-point designs, making it the preferred choice when working on corroded or high-torque fasteners. It is intended for manual drive use with a standard 1/2 inch drive handle, ratchet, or torque wrench.

Key Features

• 17 mm socket size with 6-point contact for secure fastener engagement
• 1/2 inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Alloy steel construction with chrome-plated finish for corrosion resistance
• Standard length at 1.5 inches overall for general-purpose fastener access
• Manufactured to ASME B107.5 dimensional and performance standards
• Not tether capable — intended for conventional hand-tool use environments

Compatibility

Designed as an OEM-style hand socket for use with any standard 1/2 inch drive ratchet, breaker bar, extension, or torque wrench accepting square drive tooling.

Installation Notes

This socket is installed and removed by hand tool professionals across mechanical, HVAC, plumbing, and electrical trades wherever 17 mm hex fasteners are encountered. Before use, inspect the socket for cracks or deformation and confirm the drive detent engages fully with the drive tool. Do not use hand sockets with impact drivers unless the socket is rated for impact use. Always ensure fastener and socket sizes match to avoid slippage and fastener damage.
