The PROTO J5011H is a 6-point deep hand socket designed for 3/8 inch drive ratchets and breaker bars. The socket fits 11/32 inch fasteners and features a deep-length profile that reaches recessed nuts and bolts in tight or deep cavities. Constructed from alloy steel with a chrome-plated finish, it resists corrosion and handles the torque demands of daily trade use. The 6-point design grips fastener flats rather than corners, reducing rounding under load. This socket meets ASME B107.1 standards and carries a limited lifetime warranty, making it a reliable choice for mechanics, HVAC technicians, plumbers, and electricians working with recessed or deeply set hardware.
The J5011H is suited for hand-tool use in residential and commercial service environments. Its deep-length geometry is particularly useful when driving fasteners that sit below a surface or inside a housing, such as panel bolts, manifold fasteners, and equipment mounting hardware. The 3/8 inch drive size is a common choice for medium-duty fastening tasks where a compact drive setup is preferred. This socket is intended for manual ratchet, flex-head, and breaker bar use only and is not rated for impact use.
Designed as a standard 3/8 inch drive deep hand socket for use with any 3/8 inch drive ratchet, extension, or breaker bar accepting conventional square-drive sockets.
This socket is intended for hand-drive use only and should not be used with pneumatic or electric impact tools. Verify fastener size before applying torque to avoid rounding. Inspect the socket for cracks or deformation before each use. Clean and dry the socket after use to maintain the chrome finish and extend service life.
