Proto 1/4" Drive Black Oxide Socket 9/32" - 12 Point J4709TB-SBD

Proto's J4709TB-SBD (also identified as model J4709TB) is a professional-grade 1/4 inch drive 9/32 inch socket engineered for precision mechanical work. This industrial-strength component features a 12-point configuration, which provides twice as many engagement positions as standard 6-point sockets, making it essential for high-performance tasks in tight or restricted spaces. Finished in a specialized black oxide, the J4709TB-SBD offers superior corrosion resistance and a non-reflective surface, ideal for harsh environments 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 9/32 inch fractional (SAE) size with a 1/4 inch drive end, compatible with all standard 1/4 inch ratchets, breaker bars, and extensions.
Total product weight of 0.02 lbs (approximately 0.009 kg) provides an ultra-lightweight, precision-oriented feel for delicate or small-scale mechanical work.
12-point socket geometry facilitates easier engagement with fasteners, allowing for effective rotation even at a thirty degree offset in cramped areas.
Engineered with the TorquePlus internal design, which shifts contact stress away from the fastener corners and onto the flats to prevent rounding.
Industrial black oxide finish provides a durable, non-reflective layer of protection against rust, chemicals, and industrial fluids.
Standard length design with an overall length of 7/8 inch, offering a low profile for accessing hardware in shallow or obstructed spaces.
Precision-forged from high-strength alloy steel to ensure a long service life and reliable performance under professional mechanical loads.
Manufactured to meet or exceed ASME B107.110 technical standards for professional tool safety and industrial-grade performance.
