Coach bolt M10x25 DIN 603 A2 stainless steel

Coach bolt M10x25 DIN 603 made of A2 stainless steel (1.4301, grade 304) is a fastener designed for mounting photovoltaic structures. The round head with square neck (so-called locking head) prevents the bolt from rotating while the nut is being tightened, which significantly speeds up work on the roof and eliminates the need to hold the head with a second spanner. The locking function of the square neck effectively prevents the connection from loosening due to ambient vibrations, ensuring lasting stability of the entire solar infrastructure. Austenitic A2 stainless steel guarantees exceptional corrosion resistance thanks to the nickel content in the alloy — the bolt retains its full mechanical properties across a wide range of weather conditions, from intense sunlight to rain and frost.

Advantages of the DIN 603 coach bolt in PV installations

  • Square neck locks rotation — one-handed installation, no need to hold the head
  • Round head with no sharp edges — does not damage aluminium profiles or anti-corrosion coatings
  • A2 austenitic steel — non-magnetic, flexible and resistant to stress
  • Corrosion resistance in all environmental conditions — ideal for outdoor installations
  • Compliance with DIN 603 ensures interchangeability and repeatability of connections
