The hot dipped galvanised throughbolt is a torque controlled fixing suitable for use in concrete from C20/25 to C50/60. The hot dipped galvanised finish to a minimum thickness of 42um offers good corrosion resistance together with excellent load bearing capabilities.
Ideal for fixing brackets, cladding, restraints, racking, fabricated stairwells and industrial doors.
Ensure the correct socket drive or spanner is used to ensure accurate installation.
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. Galvanising is a plating that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity as it is formed. The galvanising, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.
