The Mueller-Kueps Special Counter-Holding Wrench Kit, No. 431 030, is designed to access hard-to-reach nuts on a vehicle's strut mounting plate. It features a 13mm and 14mm wrench with both a 6- and 8-point, making it ideal for tricky connections that require a specialized tool. By holding the nut in place after it has broken loose due to rust, this tool prevents the nut from spinning and allows for efficient and precise work, even in tight spaces. This kit is particularly suitable for VW vehicles where it can be difficult to access the strut mounting plate connections.
