Wera professional photovoltaic installation set, 7 pieces, with pistol-type torque screwdriver and tools for MC4 connectors

Wera Photovoltaic Mounting Set, a complete professional solution for fast, safe and precise installation of modern solar systems

Reliable torque performance:

• At the core of the set is the Wera 7442 adjustable torque screwdriver with pistol handle, optimized for ergonomics and precision. The torque range of 3.0–6.0 Nm is ideal for sensitive photovoltaic applications, where controlled torque is essential to avoid damaging connectors and components. The digital torque display allows fast and intuitive adjustment without extra tools, while the “slip-over” mechanism and audible signal confirm when the set value is reached.

Professional solar connectivity:

• Two dedicated MC4 tools (9108) are included for easy installation of Multi-Contact connectors, used as standard in most photovoltaic systems. These tools are robust, precise, and essential for ensuring secure, damage-free connections.

Maximum productivity with Rapidaptor:

• The 889/4/1 F Rapidaptor bit holder with free-spinning function provides smooth, fast workflow. Thanks to Wera’s instant bit-change technology, the tool does not need to be removed to reset the position during clockwise torque applications—this detail significantly improves productivity.

Joker 6003 wrench – for impossible spaces:

• The 17 mm Joker 6003 wrench is specially designed to work in very tight spaces, often found in solar panel mounting structures. Its innovative geometry—with a 7.5° angled open end and double hex profile—allows repositioning every 15°, giving excellent flexibility even in restricted areas.

Special socket with lateral cutout:

• The set includes a 17 mm socket with side cutout, perfect for screwing panel connectors without stressing or damaging adjacent cables. The 870/4 adapter completes the setup, allowing seamless connection between 1/4" and 1/2" drive tools.

Practical organization and portability:

• All components come packed in a compact, robust case, with dimensions of 240 × 130 × 65 mm and a total weight of 938 g. The included Velcro strap (120 × 50 mm) provides extra fastening or organizing options, useful when working on the go or in temporary setups.
