Proto J5336H Deep Hand Socket 1/2 Drive 1-1/8 Inch 6-point

Product Description

The PROTO J5336H is a deep hand socket designed for 1/2 inch drive ratchets and breaker bars. It accepts a 1-1/8 inch fastener and features a 6-point contact profile that grips hex fasteners squarely, reducing the risk of rounding corners under high torque. The socket is manufactured from alloy steel with a chrome-plated finish that resists corrosion and makes surface cleaning easier. At 3.25 inches overall length, the deep configuration provides clearance for threaded studs, long bolt shanks, and recessed fasteners that standard-depth sockets cannot reach. This socket meets ASME B107.1 standards and is suited for use by mechanics, pipefitters, HVAC technicians, and plumbers working on heavy fastening applications.

The J5336H is a practical fit for service work in mechanical rooms, equipment installations, and field repairs where 1-1/8 inch fasteners appear on flanges, pipe fittings, conduit hardware, and HVAC equipment mounting hardware. The deep-well design handles applications where a fastener sits below a surface or has excess thread extending beyond the nut. It is intended for hand-drive use only with 1/2 inch drive tooling and is not tether capable, making it appropriate for standard ground-level or bench work environments where dropped-tool policies do not require tethering.

Key Features

• 6-point contact geometry grips fastener flats squarely to reduce rounding under torque
• Deep-well length of 3.25 inches accommodates studs and recessed or protruding fastener threads
• Alloy steel construction provides strength for high-torque hand-drive applications
• Chrome-plated finish resists corrosion and simplifies cleaning in shop and field environments
• Meets ASME B107.1 standard for hand socket performance and dimensional requirements
• 1/2 inch square drive fits standard ratchets, breaker bars, and torque wrenches

Compatibility

Designed for use with standard 1/2 inch drive ratchets, extensions, breaker bars, and torque wrenches. Fits all 1-1/8 inch hex fasteners within the torque capacity of 1/2 inch drive hand tooling.

Installation Notes

This socket is rated for hand-drive use with 1/2 inch drive tooling only. Do not use with impact wrenches unless the socket is specifically rated for impact service. Inspect the socket for cracks or deformation before each use and replace any damaged tooling. Always ensure the drive tool is fully seated in the socket before applying torque.
