Proto 1/4" Drive Black Oxide Universal Joint Socket 9/32" - 12 Point J4777TAB-SBD
Details
Proto's 1/4 inch drive 9/32 inch universal joint socket engineered for high-precision mechanical work in extremely restricted spaces. This specialized industrial tool combines a 12-point socket with an integrated universal joint, allowing for a smooth ninety degree range of motion to reach fasteners that are impossible to access with standard straight sockets. Precision-forged from high-strength alloy steel with a non-reflective black oxide finish, it provides superior corrosion resistance and a non-slip grip. By integrating the J4709UTB into your toolkit, you benefit from Proto's advanced TorquePlus technology, which maximizes torque delivery while protecting delicate fastener corners from rounding during off-angle applications.
Key Features
Features a 9/32 inch fractional (SAE) size with a 1/4 inch drive end, designed for use with all standard 1/4 inch ratchets and extensions.
Total product weight of 0.05 lbs (approximately 0.022 kg) provides a lightweight, precision feel while maintaining the structural integrity required for universal joint movement.
Integrated universal joint design allows for a continuous fluid rotation even at extreme angles, significantly increasing productivity in obstructed mechanical environments.
12-point socket geometry provides twice as many engagement positions as standard 6-point sockets, facilitating faster fastener pickup in tight areas.
Engineered with the TorquePlus internal design, a high-performance configuration that shifts contact stress away from the fastener corners and onto the flats.
Industrial black oxide finish delivers a durable, non-reflective layer of protection against rust, chemicals, and industrial fluids.
Compact overall length of 1-1/8 inches ensures a low profile, making it a "total solution" for complex aerospace, automotive, and factory maintenance tasks.
Precision-forged from high-strength alloy steel to ensure a long service life and reliable performance under professional torque loads.
Manufactured to meet or exceed ASME B107.110 technical standards for professional tool safety and industrial-grade performance.
