Wera 05020101001 6004 Joker L Self-Setting Spanner

The Wera 6004 Joker L Self-Setting Spanner is a versatile professional hand tool designed to replace several individual spanner sizes. Its automatically adjusting parallel jaws fit metric hexagon nuts and bolts from 16mm to 19mm, as well as imperial sizes 5/8", 11/16" and 3/4", without requiring manual adjustment.

When the spanner is placed onto a compatible hexagon fastener, the jaws automatically locate the correct size. An integrated lever mechanism securely grips the nut or bolt, helping reduce slipping and minimise the risk of damaging or rounding the fastener head during use.

The built-in mechanical ratchet function allows fast, continuous tightening and loosening without repeatedly removing the spanner from the fastener. A return angle of only 30° makes the Wera Joker L particularly useful when working in confined areas where movement is restricted.
