Proto J5213MH Hand Socket 13mm 6-point 3/8 Drive

Product Description

The PROTO J5213MH is a 13 mm, 6-point hand socket designed for 3/8 inch drive ratchets and breaker bars. Built from alloy steel with a chrome-plated finish, it delivers corrosion resistance and a clean surface that stands up to regular shop use. The 6-point geometry provides full-face contact on fastener flats, reducing the risk of rounding under torque. At standard length and approximately 2.83 inches overall, this socket fits comfortably in confined spaces while maintaining solid fastener engagement. It meets AS4984A and ASME B107.110-2012 standards, confirming dimensional and performance compliance for professional use.

The J5213MH suits automotive, mechanical, and general maintenance applications where a 13 mm fastener and a 3/8 inch drive are standard. It is commonly used by automotive technicians, fleet maintenance crews, and industrial mechanics working on engines, suspension components, brackets, and assemblies that use metric hardware. The standard length profile makes it suitable for typical open-access fastener work without the reach constraints of a deep socket.

Key Features

• 13 mm socket size for common metric fasteners
• 6-point design maximizes contact area on fastener flats to reduce slippage and rounding
• 3/8 inch drive fits standard ratchets, extensions, and breaker bars
• Alloy steel construction for durability under high-torque applications
• Chrome-plated finish resists corrosion and simplifies cleaning
• Meets AS4984A and ASME B107.110-2012 standards

Compatibility

Designed for use with 3/8 inch drive hand tools including ratchets, torque wrenches, extensions, and breaker bars. Compatible with any 3/8 inch drive tool system requiring a 13 mm metric socket.

Installation Notes

Ensure the drive tool is fully seated into the socket before applying torque to prevent slippage or damage to the fastener. Inspect the socket for cracks or wear before each use. This socket is not tether capable and should be secured appropriately when working at height or in confined environments per applicable safety protocols. Cleaning with a dry cloth or solvent after use will help preserve the chrome finish.
