Product Information

Product Information

Fence Fixings – Thunderbolts.

Our Thunderbolts are a great way to secure metal bolt down post supports. Each bolt is M8 x 100mm – we recommend the 100mm bolt for extra piece of mind.

The bolts are zinc/yellow passivated for extra long lifespan. You will not need a raw plug with these fixings.

Simply drill into your existing concrete – making sure you avoid pipes and cables. Using an 8mm drill bit, drill a hole 115mm deep. Bolt the supports down into the holes. Insert the wooden fence post and tighten up the retaining bolts – that’s it.
