Proto J7217M Impact Socket 3/8 in Drive 17mm

Product Description

The PROTO J7217M is a 17mm 6-point impact socket designed for 3/8 inch drive impact wrenches and ratchets. Built for professional use, it delivers the torque transfer and wall thickness needed to handle high-stress fastener removal and installation without rounding corners or cracking under repeated impact loads. The 6-point geometry grips hex fasteners across flat surfaces rather than corners, reducing fastener damage during high-torque applications. Overall length is 1-3/32 inches, making it a compact option for tight-clearance work. Mechanics, fleet technicians, and industrial maintenance crews are the primary users of this socket.

The J7217M suits automotive, heavy equipment, and general industrial applications where a 17mm hex fastener is common. Typical use cases include suspension components, drivetrain hardware, and structural bolted assemblies. The 3/8 inch drive size positions this socket in the mid-range torque category, suitable for fasteners that exceed the practical range of 1/4 inch drive tooling but do not require the bulk of 1/2 inch drive setups. It fits standard 3/8 inch drive impact guns, flex-head ratchets, and breaker bars.

Key Features

• 3/8 inch drive accepts standard 3/8 inch drive impact tools and ratchets
• 17mm socket size for metric hex fasteners
• 6-point drive style reduces fastener rounding under high torque
• Compact 1-3/32 inch overall length suits confined work areas
• Impact-rated construction handles repeated shock loading from impact wrenches

Compatibility

Designed for use with 3/8 inch drive impact wrenches, ratchets, and breaker bars requiring a 17mm 6-point metric socket.

Installation Notes

This socket is installed and removed by hand onto any 3/8 inch drive tool. Ensure the drive detent pin or retaining ring fully seats before applying torque. Do not use impact sockets on non-impact hand ratchets under excessive cheater-bar force, as the tool interface may be damaged. Always confirm fastener size before applying torque to avoid fastener or socket damage.
