The WILLIAMS COMFORT PRODUCTS 31008 is a drive adapter designed to convert between socket drive sizes in professional hand-tool applications. It features a 3/8 inch female drive input and a 1/4 inch male drive output, allowing technicians to use smaller sockets with a larger drive ratchet or torque wrench. The overall length is 1 inch, keeping the tool profile compact for work in confined spaces. At 0.04 pounds, it adds negligible weight to a tool kit. Licensed tradespeople working across HVAC, plumbing, electrical, and general mechanical service will find this adapter a practical addition to a standard socket set.
This adapter is suited for residential and light commercial service work where a technician needs to step down from a 3/8 inch drive tool to a 1/4 inch drive socket. Typical use cases include equipment access panels, control box fasteners, and other hardware locations with limited clearance. It is sold individually and is a direct, single-unit purchase with no minimum quantity beyond one.
Designed for use with standard 3/8 inch drive ratchets, breaker bars, and torque wrenches paired with 1/4 inch drive sockets and accessories following common drive-size conventions.
This adapter is installed by hand onto a 3/8 inch drive tool before attaching the appropriate 1/4 inch drive socket. No special tools or codes are required for use. Ensure the adapter is fully seated on both the drive tool and socket before applying torque to avoid slippage or rounding fasteners.
