Proto J7438 Impact Socket 1/2 in Drive 1-3/16 in 12-pt

Product Description

The PROTO J7438 is a 12-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. Built for heavy-duty fastener removal and installation, this socket accepts a 1-3/16 inch fastener and measures 2 inches overall length, making it well-suited for confined or standard-access applications. Trade professionals in HVAC, plumbing, electrical, and general mechanical work rely on impact-rated sockets like this one to handle the high-torque output of pneumatic and cordless impact drivers without cracking or rounding. The 12-point configuration provides additional engagement positions, which is useful when working in tight spaces where full socket rotation is limited.

This socket is appropriate for residential and commercial service work, equipment installation, and maintenance tasks requiring reliable fastener drive on hex fasteners up to 1-3/16 inches. It is compatible with standard 1/2 inch drive impact tools and fits into most standard socket sets and drive extensions. The 2 inch overall length keeps it compact enough for use in moderately restricted work areas without sacrificing engagement depth.

Key Features

• 1/2 inch drive compatible with standard impact wrenches, ratchets, and extensions
• 1-3/16 inch socket size for common structural and mechanical fasteners
• 12-point design allows more engagement positions in tight-clearance applications
• 2 inch overall length suits both open and moderately confined work areas
• Impact-rated construction handles high-torque output from pneumatic and cordless tools

Compatibility

Designed for use with 1/2 inch drive impact wrenches, ratchets, and socket extensions as an OEM-style impact socket for trade and industrial service applications.

Installation Notes

Install and remove by licensed mechanics, HVAC technicians, plumbers, or electricians performing equipment service. Always ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Inspect the socket for cracks or wear before each use, and do not use impact sockets with non-impact hand-drive tools. Power down or de-energize equipment before accessing fasteners on electrical enclosures or live mechanical systems.
