Proto J5340H Deep Hand Socket 1-1/4 in 6-point 1/2 in Drive

Product Description

The PROTO J5340H is a deep hand socket designed for professional hand-tool use in mechanical, industrial, and maintenance applications. Built from alloy steel with a chrome-plated finish, this socket accepts a 1/2 inch drive and fits 1-1/4 inch fasteners. The deep-length profile at 3-1/4 inches overall accommodates extended or recessed fasteners that standard-depth sockets cannot reach. The 6-point internal geometry delivers solid contact across the full flat of a hex fastener, reducing rounding on stubborn or corroded hardware. Technicians in HVAC, plumbing, automotive, and general mechanical service rely on this type of socket for routine and heavy-duty work.

The J5340H is suited for both residential and commercial service environments wherever a 1-1/4 inch fastener is present on deep or recessed bolt installations. Typical applications include equipment mounting hardware, pipe flanges, and large mechanical assemblies. The 1/2 inch drive is a common choice for mid- to high-torque fastening tasks. Packaged as a single unit, it integrates into existing 1/2 inch drive socket sets without additional adapters.

Key Features

• Deep-length body at 3-1/4 inches overall for access to recessed or extended fasteners
• 6-point design maximizes contact on hex fastener flats, reducing fastener rounding
• Alloy steel construction for strength under high-torque hand-tool use
• Chrome-plated finish resists corrosion and simplifies cleaning in the field
• 1/2 inch drive fits standard mid-range drive tools and breaker bars
• Conforms to ASME B107.1 dimensional and performance standards

Compatibility

Designed as an OEM-style deep hand socket for use with 1/2 inch drive handles, ratchets, and extensions in standard tool sets.

Installation Notes

Installed by mechanics, HVAC technicians, plumbers, and electricians using standard 1/2 inch drive ratchets or breaker bars. Ensure the fastener head is clean and fully seated in the socket before applying torque to prevent slippage. Inspect the socket for cracks or wear before use on high-torque applications. This socket is not tether-capable and should not be used in elevated work environments that require tool-tethering under fall-hazard protocols.
