Proto J5334B Deep Hand Socket 1-1/16 in 12-point

Product Description

The PROTO J5334B is a deep hand socket designed for fastener work requiring extended reach. Built from alloy steel with a black oxide finish, it seats on a 1/2 inch drive and accepts 1-1/16 inch fastener heads. The 12-point geometry engages hex and double-hex fasteners, allowing entry at multiple angles in tight working positions. At 3-1/4 inches overall length, the socket reaches recessed or deeply countersunk fasteners that standard-depth sockets cannot access. It meets ASME B107.1 standards and carries a limited lifetime warranty. Licensed trades and maintenance mechanics turn to this socket for mechanical, structural, and equipment assembly tasks across a range of industries.

This socket is suited for residential, commercial, and industrial maintenance applications. It is commonly used in HVAC equipment assembly, plumbing fixture installation, electrical panel work, and general mechanical service where 1/2 inch drive tools are standard. The deep length makes it particularly useful when working on engine mounts, equipment frames, or threaded rod applications where fastener depth exceeds what a standard socket can safely engage.

Key Features

• 1-1/16 inch socket size fits standard and metric-equivalent fastener heads
• 12-point design allows engagement at 30-degree increments for use in restricted spaces
• Deep length at 3-1/4 inches overall accommodates recessed or stacked fasteners
• Alloy steel construction provides durability under high-torque hand drive use
• Black oxide finish resists surface corrosion in shop and field environments
• Meets ASME B107.1 standards for hand socket tools

Compatibility

Designed for use with 1/2 inch drive ratchets, breaker bars, and torque wrenches. Compatible with standard 1/2 inch drive extensions and universal joints.

Installation Notes

This socket is installed and removed by hand using a 1/2 inch drive ratchet or torque wrench. Ensure the fastener head is fully seated in the socket before applying torque to avoid rounding. Inspect the socket for cracks or deformation before each use and do not use impact drivers with hand-rated sockets unless the socket is rated for impact service.
