Frequently Asked Questions About Fence Post Spikes

Q: What are fence post spikes used for?

A: Fence post spikes are steel supports designed to secure timber posts into the ground without digging or using concrete. They are commonly used for fencing, decking, pergolas, gazebos, and other garden structures.

Q: Are fence post spikes strong enough for fencing?

A: Yes. Galvanised fence post spikes provide excellent stability when driven deep into the ground. For taller or heavier fences, choose longer, heavy-duty spikes (e.g. 750mm).

Q: How do you install a fence post spike?

A: Position the spike, drive it into the ground using a sledgehammer or driving tool, check alignment, then insert your timber post into the holder and tighten the bolts. No digging or concrete required.

Q: Can fence post spikes be used on concrete or hard ground?

A: Standard drive-in spikes are best for soil. For concrete or patios, use bolt-down post supports instead, which secure posts to solid surfaces.


Q: Do galvanised post spikes rust?

A: Our spikes are hot-dip galvanised to resist rust and corrosion. With proper installation, they last many years even in wet conditions.

Q: What size fence post spike do I need?

A: Match the internal box size of the spike to your timber post (e.g. a 75×75mm post requires a 75×75mm spike). Longer spikes give extra stability in softer ground.

Q: Are fence post spikes reusable?

A: Yes, post spikes can often be reused if removed carefully, though some may show wear after heavy use or removal from hard ground.
