Proto J7216M Impact Socket 3/8 in Drive 16mm 6-pt

Product Description

The PROTO J7216M is a 6-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. Built for the demands of professional trade work, this socket accepts a 16mm fastener and measures 1-3/32 inches overall length. The 6-point hex drive geometry maximizes contact area on fastener flats, reducing the risk of rounding under high-torque impact conditions. It is a straightforward, duty-rated socket suited for automotive, mechanical, and general industrial fastening tasks performed by mechanics, HVAC technicians, plumbers, and other trades who rely on impact tooling daily.

The J7216M fits standard 3/8 inch drive impact tools and is well-suited for use in tight quarters where a compact overall length is an advantage. The 16mm socket size covers a common fastener dimension found across automotive, HVAC equipment, and mechanical systems. This socket is sold individually, making it a practical replacement or addition to an existing impact socket set without requiring a full kit purchase.

Installation Notes

Install this socket onto a 3/8 inch drive impact wrench or ratchet by pressing firmly onto the drive anvil until the detent ball engages. Confirm the socket is fully seated before applying torque. When using with a pneumatic or electric impact wrench, verify that the tool torque output is appropriate for the fastener application to avoid fastener damage. Always wear appropriate eye protection when operating impact tools.
