Fence Post Spikes
Fence post spikes provide a fast and secure way to install timber posts without digging or concreting, saving time while delivering a strong, long-lasting hold.
Drive in post spikes are designed to securely fix timber fence posts into the ground without the need for digging holes or using concrete.
Also known as fence post ground spikes or fence post spikes, they are ideal for fencing, decking, and garden structures where speed and ease of installation are essential.
Featuring a 4-fin steel spike, they drive directly into the ground to create a solid, wind-resistant fixing while keeping the timber post raised above ground level to help prevent rot and decay.
What are fence post spikes?
Drive in post spikes are steel supports that are hammered into the ground to hold timber posts securely in place.
They eliminate the need for concrete and allow posts to be installed quickly while still providing strong support.
What are drive in post spikes used for?
- Installing fence posts without digging or concreting
- Securing garden structures such as pergolas and decking posts
- Temporary or permanent fencing solutions
- Reducing installation time on-site

Driving tools
Drive in post spike driving tools are used to safely install spikes into the ground without damaging the post holder section.
Made from hardened plastic, they absorb impact from a hammer or post driver and protect the spike during installation.
Available in 75mm and 100mm sizes to match common post spike dimensions.
Available finishes
| Finish | Protection Level | Best Use | Appearance |
|---|---|---|---|
| Oxide Red | Medium | General fencing and garden use | Blends with timber, can be painted |
| Hot Dipped Galvanised | High | Long-term outdoor and exposed environments | Silver metallic finish |
How to install bolt secure post spikes
- Position the spike in the correct location
- Use a driving tool to hammer the spike vertically into the ground
- Check alignment regularly during installation
- Insert the timber post into the holder
- Tighten the carriage bolts to clamp the post securely
How to install quick fit post spikes
- Position the spike and drive it into the ground using a driving tool
- Ensure the spike is level and aligned
- Insert the post into the holder
- Tap the post down firmly so the internal fins grip tightly

Related fence post fixings
Drive in fence post spikes are part of a wider range of post fixing solutions, each suited to different installation methods and ground conditions.
If you’re working with existing posts or need alternative fixing methods, you may also want to consider:
- Repair spikes – ideal for reinforcing or fixing damaged posts already set in concrete
- Post extenders – used to extend the height of existing fence posts
- Bolt down shoes – perfect for fixing posts onto concrete or hard surfaces
- Concrete in shoes – best for permanent installations where maximum strength is required
Common mistakes when installing fence post spikes
- Driving the spike in at an angle – always keep it level for a straight, stable post
- Not using a driving tool – this can damage the post holder and reduce lifespan
- Installing in very hard or stony ground – may require pilot holes or an alternative fixing method
- Using the wrong size spike – always match the spike to the post size (e.g. 75 x 75mm or 100 x 100mm)
- Not driving the spike deep enough – deeper installation improves strength and wind resistance
