Proto 3/8" Drive Black Oxide Socket 1/4" - 12 Point J5208B-SBD
Details
Proto's J5208B-SBD (also identified as model J5208B) is a professional-grade 3/8 inch drive 1/4 inch deep socket engineered for precision mechanical work in demanding industrial and automotive environments. This high-performance tool features a 12-point configuration and a deep-well design, making it essential for reaching fasteners on long bolts or in recessed areas where standard sockets cannot reach. Finished in a specialized black oxide, the J5208B-SBD offers superior corrosion resistance and a non-reflective surface, making it ideal for harsh settings where standard chrome plating might chip or peel. By integrating this socket into your toolkit, you benefit from Proto's advanced TorquePlus technology, which maximizes torque delivery while protecting fastener corners from rounding.
Key Features
Features a 1/4 inch fractional (SAE) size with a 3/8 inch drive end, ensuring compatibility with all standard 3/8 inch ratchets, breaker bars, and extensions.
Deep-well profile with an overall length of 1-3/4 inches allows for easy access to nuts on long protruding bolts and deep-seated fasteners.
12-point socket geometry facilitates easier engagement with fasteners, allowing for effective rotation even at a thirty degree offset in cramped mechanical areas.
Engineered with the TorquePlus internal design, which shifts contact stress away from the fastener corners and onto the flats to prevent rounding and extend hardware life.
Industrial black oxide finish provides a durable, non-reflective layer of protection against rust, chemicals, and industrial fluids.
Precision-forged from high-strength alloy steel to ensure a long service life and reliable performance under professional mechanical loads.
Total product weight of 0.08 lbs (approximately 0.036 kg) provides a robust yet precision-oriented feel for small-diameter high-reach applications.
Manufactured to meet or exceed ASME B107.110 technical standards for professional tool safety and industrial-grade performance.
