M6x20 Mushroom Head Combi-Drive Tray Bolts Galvanised With Serrated Nuts


  • Mushroom head combi drive tray bolts.
  • Hot dip galvanised.

Galvanised for increased protection against corrosion.

Galvanised coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Galvanise is a coating that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity
