Proto J5412 Hand Socket 3/8 Inch 12-point 1/2 Drive

Product Description

The PROTO J5412 is a 12-point hand socket designed for 3/4-inch drive applications where controlled torque and accessibility matter. Built from alloy steel with a chrome-plated finish, this standard-length socket measures 1-31/64 inches in overall length and weighs 0.1 pounds. The 12-point design provides more engagement positions around a fastener head, making it useful in tight clearances where full rotation of the drive tool is not possible. It meets ASME B107.110-2012 and AS4984A standards, confirming it is manufactured to recognized dimensional and performance specifications. Mechanics, pipefitters, and maintenance technicians working in industrial and commercial environments are the primary users of this socket.

The PROTO J5412 is suited for use in industrial maintenance, mechanical assembly, and general repair work where 3/8-inch fasteners are common. The standard-length profile fits most drive extensions and ratchets with a 1/2-inch square drive. Its chrome finish resists corrosion in typical shop and field conditions. The 12-point geometry is particularly useful when working on hex fasteners that have worn corners, as more contact points distribute the load across the fastener head. This socket is sold individually and is not tether-capable, making it appropriate for standard ground-level or bench use rather than elevated or overhead work environments where dropped-tool protocols apply.

Key Features

• 12-point design allows engagement in 30-degree increments for use in limited-swing applications
• Alloy steel construction for durability under torque loads
• Chrome-plated finish for corrosion resistance and easy cleaning
• Standard-length profile at 1-31/64 inches overall length
• Meets ASME B107.110-2012 and AS4984A dimensional standards
• 1/2-inch square drive compatible with standard ratchets and extensions

Compatibility

Designed for use with 1/2-inch square drive ratchets, breaker bars, and extensions. Fits 3/8-inch 12-point fastener heads in standard residential, commercial, and industrial maintenance applications.

Installation Notes

This socket is installed and removed by licensed mechanics, maintenance technicians, and tradespeople using standard 1/2-inch drive tools. Always ensure the socket is fully seated on the fastener before applying torque to avoid rounding. This socket is not rated for tethered use and should not be used overhead or in elevated work areas without additional tool-retention measures. Inspect the socket for cracks or deformation before each use and retire any damaged sockets from service.
