The WILLIAMS COMFORT PRODUCTS BS-130B is a 3/8 inch female to 1/2 inch male drive adaptor finished in black. This fitting converts a 3/8 inch female drive socket connection to a 1/2 inch male drive, allowing technicians to pair tools and sockets of different drive sizes without swapping entire socket sets. It is a compact, single-piece adaptor suited for use in tight mechanical spaces where tool interchangeability is required. Weighing just 0.08 pounds, the BS-130B is a lightweight addition to any field service kit used by HVAC technicians, plumbers, electricians, or general mechanical tradespeople.
This drive adaptor is appropriate for professional trade use wherever 3/8 inch and 1/2 inch drive tools must be used together on the same fastener. Common applications include equipment service panels, motor mounts, and mechanical fasteners encountered during HVAC unit installation, plumbing fixture work, or electrical enclosure servicing. The black finish provides a consistent, corrosion-resistant surface for repeated shop and field use. It is sold individually and requires no additional hardware for use.
Designed as a standard drive adaptor compatible with 3/8 inch female drive sockets and 1/2 inch male drive ratchets, breaker bars, and impact tools commonly used in HVAC, plumbing, and electrical service work.
No installation is required for this adaptor. Ensure the drive connection is fully seated before applying torque to avoid slippage or rounding of the drive fitting. Always confirm the adaptor is rated for the torque demands of the fastener being driven. Inspect the adaptor for wear or deformation before each use, particularly when used with impact tools.
