Proto J5436MH 36mm 6-point 1/2 Drive Hand Socket

Product Description

The PROTO J5436MH is a 36 mm, 6-point hand socket designed for 1/2-inch drive ratchets and breaker bars. Built from alloy steel with a chrome-plated finish, it delivers the corrosion resistance and surface hardness that professional mechanics and industrial technicians expect on the job. The standard-length body measures 2.3 inches long and fits within the B107.5M dimensional standard, making it a precise, code-compliant choice for torquing large fasteners in automotive, heavy equipment, and industrial maintenance applications. At 0.89 pounds, it provides solid heft without adding unnecessary bulk to a socket set.

This socket is suited for professional service environments where 36 mm fasteners appear on drivetrain components, suspension assemblies, heavy equipment linkages, and industrial machinery. It is a standard-length socket, appropriate for general-purpose wrenching where deep-reach clearance is not required. Licensed mechanics, fleet maintenance technicians, and industrial maintenance professionals will find it at home in both shop and field settings.

Key Features

• 36 mm socket size for large fastener applications
• 6-point contact geometry reduces fastener rounding under high torque
• 1/2-inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Alloy steel construction with chrome-plated finish for corrosion resistance
• Meets ASME B107.5M dimensional standards
• Limited lifetime warranty coverage

Compatibility

Designed for use with any 1/2-inch drive ratchet, breaker bar, extension, or torque wrench. Compatible with standard 1/2-inch drive accessories meeting ASME B107.5M specifications.

Installation Notes

This socket is installed and removed by hand tool technicians — no special certifications are required for use. Ensure the fastener and socket are fully seated before applying torque to avoid slippage or fastener damage. Inspect the socket for cracks, deformation, or worn drive tangs before each use. Do not use impact drivers or pneumatic tools with a hand socket unless the socket is explicitly rated for impact use.
