Frequently Asked Questions
What is the K2 Systems SC M8x40 mm socket head cap screw?
It is a hexagon socket head cap screw (cylinder head) with an M8 x 40 mm thread according to DIN 912 / ISO 4762. It is made of stainless steel and serves as a connecting element in photovoltaic mounting systems.
What is the screw used for in a PV mounting system?
The M8x40 screw connects components of the substructure -- such as rails, connectors, and clamps. With its 40 mm thread length, it is suitable for screw connections with a larger clamping range.
What does the underhead serration do?
The serrated head support grips the contact surface and secures the connection against self-loosening due to vibration, wind loads, and temperature changes -- an additional locking washer is often unnecessary.
What tool drive do I need?
The screw has an internal hexagon with a wrench size of SW 6. A suitable Allen key or a hex bit is sufficient for tightening.
Is the screw suitable for outdoor use on the roof?
Yes. The stainless steel design is corrosion and weather resistant and is therefore designed for permanent outdoor installation in PV systems.
