Proto J5317M Deep Hand Socket 17mm 12-point 1/2 Drive

Product Description

The PROTO J5317M is a 17 mm, 12-point deep hand socket designed for 1/2 inch drive ratchets and breaker bars. Constructed from alloy steel with a chrome-plated finish, it delivers the durability and corrosion resistance required for regular shop and field use. At 3.25 inches overall length, the deep profile provides clearance for extended fasteners, studs, and recessed bolt heads that standard-depth sockets cannot reach. This socket meets ASME B107.110-2012 and SAE AS955 standards, making it appropriate for professional mechanical, HVAC, plumbing, and electrical trade applications where fastener access depth is a factor.

The J5317M is suited for automotive, mechanical, and general trade service work where a 17 mm fastener is common. The deep length is particularly useful when working around protruding threads or in recessed cavities found in equipment panels, mechanical assemblies, and utility connections. It is a hand-drive socket intended for use with 1/2 inch drive tools and is not rated for impact use. Trades including HVAC service technicians, plumbers, and electricians routinely carry 17 mm deep sockets for equipment mounting hardware and service connections.

Key Features

• 17 mm socket size with 12-point configuration for engagement flexibility on standard hex fasteners
• 1/2 inch drive compatible with ratchets, breaker bars, and torque wrenches
• Deep length profile at 3.25 inches overall for clearance on studded or recessed fasteners
• Alloy steel construction for strength under high-torque hand-drive applications
• Chrome-plated finish resists corrosion and simplifies cleaning
• Meets ASME B107.110-2012 and SAE AS955 standards

Compatibility

Designed as a standard 1/2 inch drive deep hand socket compatible with 1/2 inch drive ratchets, extensions, and torque wrenches from any manufacturer conforming to industry drive standards.

Installation Notes

This socket is intended for hand-drive use only and should not be used with impact wrenches unless the tool is specifically rated for impact service. Ensure the drive tool is fully seated in the socket before applying torque to prevent slippage or rounding of the fastener. Inspect the socket for cracks or deformation before each use, and retire any socket showing signs of damage. General mechanical service should follow applicable industry codes and equipment manufacturer torque guidelines.
