Wera hand tools now include ratchets and sockets, as well as combination wrenches, nut drivers, chisel drivers and additional screwdrivers. Seven-piece nutdriver sets made of chrome-plated steel feature hollow shanks to allow access to nuts on long screws, and are available in inch and metric sizes. Suitable for fastening, chiseling and loosening seized screws, chisel screwdrivers feature a hexagonal blade which goes through the ergonomic handle to an impact cap fitted with a ¼ in. square socket to allow adding a ratchet for extra torque.
