Universal 4-Way Utility Key

The Universal 4-Way Utility Key are a compact tools designed for opening many common electrical, water and service cabinets. It combines four different sockets in a single key: a 6 mm square, an 8 mm square, a 10 mm triangular, and an 8 mm triangular socket, covering a wide range of utility access points.

For maximum durability, it is strongly recommended to print this model in ABS or PETG rather than PLA, as these materials offer better impact and wear resistance. Use a high infill percentage (40-70%) and at least 3 perimeters/walls to ensure the tool can withstand the torque required during regular use.

Required Hardware

• 3 × DIN 912 M3×10 socket head screws

• 3 × M3 nuts

All mounting features are already integrated into the model. Simply insert the nuts into the hexagonal pockets and tighten the screws to complete the assembly.
