The WILLIAMS COMFORT PRODUCTS 30406 is a 3/16-inch, 12-point deep socket with a 1/4-inch drive. It is designed for reaching fasteners in recessed or obstructed locations where a standard-depth socket cannot engage. The 12-point geometry provides more contact positions per rotation, making it useful in tight-swing situations. Mechanics, maintenance technicians, and trade professionals use deep sockets like this one for assembly and disassembly tasks across HVAC equipment, electrical panels, plumbing fixtures, and general mechanical systems.
This socket fits standard 1/4-inch drive ratchets, extensions, and torque wrenches. The 3/16-inch size is commonly encountered on smaller fasteners found in control panels, access covers, fan assemblies, and light-duty equipment frames. It is sold individually and is suited for both shop use and field service kits where compact tooling is required.
Designed for use with standard 1/4-inch drive ratchets, extensions, and adapters commonly found in professional tool sets.
Ensure the drive tool and socket are fully seated before applying torque to avoid rounding the fastener or damaging the socket. Inspect the socket for cracks or wear before each use, particularly in high-cycle field applications. Follow applicable equipment service manuals for fastener torque requirements when reassembling components.
