Apex cds42n 3/8 Drive 12mm 12-point Metric Socket

Product Description

The APEX cds42n is a 3/8 inch drive, 12-point standard metric socket sized at 12mm. Built from Crestoloy alloy steel, it delivers the strength needed for regular production and service work. The nickel chrome plating resists corrosion and maintains a clean finish over repeated use. An off-corner loading design shifts contact away from fastener corners, reducing the risk of rounding on hex heads. This socket is suited for professional mechanics, maintenance technicians, and trade professionals who need reliable hand tools for metric fastener applications.

The cds42n fits standard 3/8 inch drive ratchets, extensions, and breaker bars. It is appropriate for automotive, HVAC, plumbing, and general mechanical service work where 12mm metric fasteners are encountered. The 12-point geometry allows engagement at 30-degree intervals, which is useful in confined spaces where swing arc is limited. It meets or exceeds ASME requirements, making it suitable for professional service environments.

Key Features

• 3/8 inch drive fits standard ratchets, extensions, and breaker bars
• 12mm size, 12-point geometry for 30-degree engagement intervals

Compatibility

Designed as a standard 3/8 inch drive metric socket compatible with 3/8 inch drive ratchets, torque wrenches, extensions, and adapters from major hand tool manufacturers.

Installation Notes

Installed and used by mechanics, HVAC technicians, plumbers, and electricians during equipment service and assembly. Ensure the socket is fully seated on the fastener head before applying torque to prevent slippage. Inspect the socket and drive square for wear or cracks before use, and do not use with impact drivers unless the socket is rated for impact service.
