Proto J7217MHF Impact Socket 3/8 in Drive 17mm 6-pt

Product Description

The PROTO J7217MHF is a 17mm, 6-point impact socket with a 3/8 inch drive, designed for use with impact wrenches and air tools in professional trade and industrial settings. Built from alloy steel, it delivers the wall thickness and hardness required to handle the torque output of pneumatic and electric impact drivers without cracking or rounding. The magnetic design holds fasteners during placement, reducing drop risk in tight or elevated work areas. At 1.25 inches overall length, it fits compact spaces where longer sockets would bind. Licensed tradespeople and professional mechanics reach for this socket when working on fasteners that demand controlled, repeatable torque.

This socket suits residential, commercial, and industrial applications wherever 17mm hex fasteners are encountered. Common use cases include mechanical and electrical panel assembly, HVAC equipment installation, plumbing fixture mounting, and general equipment service. The 3/8 inch drive size is standard across a wide range of impact wrenches and hand ratchets, making this socket a versatile addition to a trade tool kit. It is equally at home in a shop setting or on a service call.

Installation Notes

Install and remove using a 3/8 inch drive impact wrench or ratchet by a qualified technician or mechanic. Ensure the drive tool is powered down or the air supply is disconnected before changing sockets. Inspect the socket for cracks or deformation before each use and retire any socket showing visible wear. Do not use impact sockets on non-impact hand tools beyond their rated torque range.
