WERA 869/4 nutsetter 7.0 mm
The WERA 869/4 is a nutsetter for hexagonal screw heads. It is used to tighten or loosen a nut or screw with an external hexagonal head using a machine or a holder that takes a 1/4" hexagon. This is a 7.0 mm size with a length of 65 mm.
The non-magnetic design is relevant when you want to prevent the tool from attracting metal shavings. This makes it more suitable for tasks where you are working close to small metal parts, and where it is practical that bits and accessories do not unnecessarily collect shavings.
The connection is designed for the Wera connecting series 4 and for holders according to DIN ISO 1173-F 6.3. This means it fits into a common 1/4" system, which many use in assembly and service work.
