Socket 1" Sq. Dr. 12-P 57mm

Socket 1" Sq. Dr. 12-P 57mmKoken 1 inch square drive 12 point socket in 57 mm is engineered to provide accurate fastener engagement and stable torque transfer for heavy duty automotive, industrial, and equipment service applications. Manufactured to precise dimensional tolerances, this socket ensures a consistent fit on metric fasteners, supporting smooth rotation and controlled performance under demanding load conditions. The 12 point design increases the number of engagement positions, improving accessibility and efficiency when working in restricted spaces with limited swing angles. Carefully optimized wall thickness maintains structural strength while preserving a practical outer profile suitable for professional tool systems and large drive assemblies. Koken advanced machining processes and stringent quality standards support long term dimensional stability, resistance to wear, and dependable service life during repeated high torque use. The precision formed drive end ensures secure attachment to 1 inch square drive ratchets, extensions, and torque tools, while the refined surface finish enhances corrosion resistance and allows for straightforward maintenance, reflecting the professional manufacturing quality associated with Koken.
