Proto J5342 Deep Hand Socket 1-5/16 in 1/2 Drive 12-point

Product Description

The PROTO J5342 is a deep hand socket designed for professional hand-tool use in mechanical, industrial, and maintenance applications. Built from alloy steel with a chrome finish, it accepts a 1/2 inch drive and fits a 1-5/16 inch fastener. The 12-point configuration allows engagement from multiple positions, which is useful when working in restricted spaces. At 3.5 inches in overall length, the deep profile provides clearance over long studs, bolt ends, and recessed fasteners. This socket meets ASME B107.110-2012, AS4984A, and SAE AS954G standards, making it appropriate for applications that require traceable tool compliance. Mechanics, millwrights, and maintenance technicians are the primary users.

This socket fits into general mechanical and industrial maintenance work where deep reach on 1-5/16 inch fasteners is required. Typical applications include automotive, heavy equipment, and structural assembly where studs or extended bolt threads prevent a standard-depth socket from seating. The 12-point geometry works with both standard and impact-style 1/2 inch drive handles, ratchets, and torque wrenches. Its chrome finish provides corrosion resistance in shop and field environments.

Key Features

• 1-5/16 inch socket size fits common fastener diameters in mechanical and industrial work
• 12-point design allows multiple engagement positions in tight spaces
• Deep length of 3.5 inches clears studs and recessed fastener applications
• Alloy steel construction with chrome finish for strength and corrosion resistance
• Meets ASME B107.110-2012, AS4984A, and SAE AS954G compliance standards
• 1/2 inch drive fits standard ratchets, breaker bars, and torque wrenches

Compatibility

Designed as an OEM-style deep hand socket for use with standard 1/2 inch drive hand tools including ratchets, extensions, and torque wrenches requiring a 1-5/16 inch socket.

Installation Notes

This socket is intended for use by mechanics, millwrights, and trained maintenance personnel. Ensure the fastener and socket are fully seated before applying torque to prevent rounding. Inspect the socket for cracks or wear before each use. Do not use hand sockets with pneumatic or hydraulic impact drivers unless the tool is rated for impact use.
