This AWA throughbolt is a torque controlled through fixing suitable for use in concrete over C20/25. The zinc plated and clear passivated anchors has a wide range of diameters and lengths together with excellent load bearing capacities.
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.
Zinc 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. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity as it is formed. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminium and stainless steels by their oxide layers.
