The Wera 780B/2 is a precision-engineered adaptor that converts a 3/8" square drive to accept 5/16" hexagon screwdriver bits, enabling professional tradespeople to use their ratchet wrenches and socket sets with a wide range of hexagonal drive bits. Manufactured to exacting DIN ISO 1173-C 8 standards, this adaptor is specifically designed for compatibility with Wera connecting series 2 bits, providing a secure and reliable connection for demanding applications. This versatile adaptor features a ball stop groove mechanism that ensures bits are held firmly in place during use, preventing accidental disengagement whilst maintaining quick and easy bit changes when required. The robust construction delivers the durability expected from Wera tools, making it ideal for automotive technicians, mechanical engineers and maintenance professionals who need to switch between socket drive tools and hex bit applications. The 780B/2 is particularly useful for accessing fasteners in confined spaces where a standard socket won't fit, and for tasks requiring the precision control of screwdriver bits combined with the leverage and ratcheting action of a socket wrench. At 30mm in length, the compact design maintains good access whilst providing sufficient extension for most applications. Features and Benefits: • 3/8" square socket drive compatible with standard ratchets and extension bars • Accepts 5/16" hexagon drive bits conforming to DIN ISO 1173-C 8 • Ball stop groove provides secure bit retention during operation • Compatible with Wera connecting series 2 bit system • Compact 30mm length maintains access in restricted spaces Contents: 780 B 3/8" Adaptor, 780 B/2 x 5/16" x 30 mm Specifications: Drive size: 3/8" square Bit holder size: 5/16" hexagon Length: 30mm
