The APEX cdds12n is a 1/4 inch drive, 6-point deep metric socket sized at 5mm, built for professional hand-tool applications in HVAC, plumbing, electrical, and general mechanical service. Manufactured from Crestoloy alloy steel, this socket is nickel chrome plated for corrosion resistance and a long-lasting finish. The off-corner loading design contacts the flat faces of the fastener rather than the corners, reducing the risk of rounding on worn or tight fasteners. It meets or exceeds ASME performance requirements, making it a reliable choice for trade professionals who depend on hand tools daily.
This deep socket is suited for reaching recessed fasteners and extended bolt threads that a standard-depth socket cannot access. The 1/4 inch drive makes it compatible with compact ratchets and extensions commonly used in tight spaces found in equipment panels, control cabinets, and mechanical assemblies. The 5mm metric sizing fits fasteners common in imported HVAC equipment, mini-split systems, and light commercial mechanical components. Suitable for residential and light commercial service work.
Designed as an OEM-style deep socket for use with standard 1/4 inch drive ratchets, extensions, and torque wrenches in professional tool sets.
This socket is installed and used by licensed HVAC technicians, plumbers, electricians, and mechanical service professionals. Always ensure the drive tool and socket are fully seated before applying torque to prevent slippage or socket damage. Inspect the socket for cracks or wear before each use and replace if damaged. Do not use impact drivers with this hand-tool socket unless it is rated for impact use.
