The APEX cdds4n is a 1/4 inch drive, 6-point deep SAE socket sized at 9/32 inch, built for professional fastener work in tight or recessed applications. Manufactured from Crestoloy alloy steel, this socket delivers the strength needed for high-torque hand and impact-assisted use. A nickel chrome plated finish resists corrosion and wear over repeated use. The off-corner loading geometry contacts the flat of the fastener rather than the corner, reducing the risk of rounding fastener heads during removal or installation. It meets or exceeds ASME requirements for hand tools.
This deep socket is suited for residential and commercial service work across HVAC, plumbing, electrical, and general mechanical applications where standard-depth sockets cannot reach recessed or stud-mounted fasteners. It is appropriate for use on equipment panels, pipe fittings, electrical enclosures, and mechanical assemblies requiring a 9/32 inch SAE fit. Licensed tradespeople and experienced mechanics will find it a direct fit for 1/4 inch drive ratchets, extensions, and flex handles.
Designed as a standard 1/4 inch drive deep socket compatible with 1/4 inch drive ratchets, extensions, and accessories using SAE sizing.
Install and remove using a 1/4 inch drive ratchet or extension bar rated for the torque requirements of the fastener. Ensure the socket is fully seated on the fastener before applying torque to avoid slippage. Inspect the socket for cracks or wear before use on critical fastener applications. Follow applicable equipment service procedures and safety lockout or tagout requirements before servicing energized or pressurized systems.
