The APEX cds11n is a 4mm, 6-point standard metric socket designed for use with 1/4 inch drive ratchets and extensions. Built from Crestoloy alloy steel, this socket delivers the strength needed for repeated professional use in trade and shop environments. The 6-point geometry combined with an off-corner load feature contacts the flat faces of the fastener rather than the corners, reducing the risk of rounding on hex fasteners under torque. Nickel chrome plating provides corrosion resistance and a durable finish suited to daily tool use. This socket meets or exceeds ASME requirements for hand tools.
The cds11n is suited for automotive, mechanical, HVAC, plumbing, and electrical work where 4mm metric fasteners are encountered. It fits standard 1/4 inch drive tool sets and is appropriate for use in tight spaces where the compact 1/4 inch drive form factor is preferred. Technicians and tradespeople working with metric hardware in residential and light commercial applications will find this socket a straightforward addition to a standard drive set.
Designed as a standard 1/4 inch drive metric socket compatible with 1/4 inch drive ratchets, extensions, and adapters that accept square drive tooling.
This socket is installed and removed by hand onto any compatible 1/4 inch drive ratchet or extension. Ensure the drive connection is fully seated before applying torque to prevent slippage. When working on live electrical panels or energized equipment, de-energize and lock out power before using hand tools on fasteners. Follow applicable codes and manufacturer service procedures for the equipment being serviced.
