Bolts are important!
It is imperative that the VBG system is assembled using the right types of bolts with the correct lengths. This is a matter of safety, since the wrong bolt can affect the strength of the system!
VBG bolt kits are surface treated with consideration given to the surrounding materials, and provide corrosion protection in salt-spray tests for up to twice as long as zinc-iron.
• Grade 10.9 is zinc-aluminium treated to prevent hydrogen embrittlement.
Always choose bolts with the least possible potential difference to the surrounding material in order to minimise corrosion.How to choose the correct bolt length
