J.161 3P12U 19 Piece 3 8" Drive Bi Hexagon Socket Set Imperial

The Facom J.161-3P12U is a 19-piece 3/8" drive bi-hexagon socket set in imperial sizes, designed for professional tradespeople working on vehicles, plant machinery, and equipment with imperial-specification fasteners. The bi-hexagon (12-point) socket profile is engineered to engage with both standard hex and 12-point fasteners, offering greater flexibility when working in tight or awkward access situations. This makes the set particularly well-suited to automotive technicians, classic car restorers, and engineers frequently working on older or American-specification machinery where imperial sizing remains standard. Manufactured by Facom, a brand with a strong reputation in the professional hand tool market, this set reflects the quality and precision expected by working tradespeople. The 3/8" drive is a versatile mid-range square drive size, offering an effective balance between torque capacity and access in confined spaces.
