Proto J5222HS 11/16 in 3/8 Drive 6-point Hand Socket

Product Description

The PROTO J5222HS is a 6-point hand socket designed for 3/8 inch drive tools. It accepts an 11/16 inch fastener and delivers a low-profile fit at 15/16 inches overall length, making it well suited for confined spaces where standard-depth sockets cannot seat properly. The socket is machined from alloy steel and finished with a chrome plating that resists corrosion and makes cleanup straightforward. Electricians, plumbers, HVAC technicians, and general maintenance professionals reach for sockets like this when working on equipment panels, valve assemblies, or mechanical connections that require a reliable hand-tool drive.

This socket is appropriate for residential and light commercial service work wherever a 3/8 inch drive ratchet, breaker bar, or extension is in use. The low-profile length designation means it fits well in recessed bolt locations or shallow fastener pockets. The 6-point contact geometry reduces the risk of rounding fastener heads compared to 12-point designs, which is particularly useful when breaking loose stubborn or corroded hardware.

Key Features

• 11/16 inch socket size fits standard hex fasteners of that dimension
• 3/8 inch drive compatible with common ratchets, extensions, and torque wrenches
• 6-point contact geometry reduces fastener rounding under load
• Low-profile overall length of 15/16 inches for use in tight clearances
• Alloy steel construction provides durability under hand-tool torque loads
• Chrome finish resists corrosion and simplifies cleaning

Compatibility

Designed as a standard 3/8 inch drive hand socket for use with compatible ratchets, breaker bars, torque wrenches, and extensions accepting 3/8 inch square drive tooling.

Installation Notes

This socket is installed and removed by hand tool only — do not use with pneumatic or hydraulic impact drivers, as impact use on non-impact-rated sockets risks cracking the socket body. Ensure the fastener is fully seated in the socket before applying torque to avoid slippage. Inspect the socket for cracks or deformation before each use and remove it from service if damage is found.
