Proto J5206HS 3/16 in 6-point 3/8 in Drive Hand Socket

Product Description

The PROTO J5206HS is a 3/16 inch, 6-point hand socket designed for precision fastener work in tight or recessed locations. Built from alloy steel with a chrome finish, this low-profile socket is sized for a 3/8 inch drive and delivers a clean, positive engagement on hex fasteners. At 3/4 inch overall length, it is suited for close-quarter applications where standard-depth sockets cannot seat properly. Licensed tradespeople and experienced technicians use this socket in mechanical, HVAC, and general industrial service work where access is limited and fastener control is critical.

This socket fits standard 3/8 inch drive ratchets, extensions, and torque wrenches. The low-profile design makes it well suited for recessed bolt patterns and confined panel or housing access points common in HVAC equipment, light mechanical assemblies, and electrical enclosures. Its compact 3/4 inch length minimizes stack height when paired with a short extension, helping technicians reach fasteners that full-depth sockets cannot access cleanly.

Key Features

• 3/16 inch socket size for small hex fasteners requiring precise fit
• 6-point geometry provides full-face contact, reducing fastener rounding under load
• 3/8 inch drive compatibility with standard ratchets, extensions, and torque wrenches
• Low-profile design at 3/4 inch overall length for confined-space access
• Alloy steel construction for durability under repeated torque loading
• Chrome finish resists corrosion and simplifies surface cleaning

Compatibility

Designed for use with standard 3/8 inch drive ratchets, extensions, and drive tools. This socket is not tether capable and is intended for conventional hand-tool applications.

Installation Notes

This socket is installed by hand-tool technicians working in mechanical, HVAC, and industrial service environments. Verify the fastener size matches the 3/16 inch socket before applying torque to avoid rounding. Ensure the socket is fully seated on the drive before use. Inspect for wear or cracking periodically, and retire the socket if deformation is observed.
