Product Information
Full details
The B&Q Cruciform Square Head Greenhouse Bolts & Nuts are designed for gardeners and DIY enthusiasts who need to assemble, maintain, or reinforce aluminum-framed greenhouses. These M6 threaded fasteners offer the key benefit of a universal fit for standard glazing channels, ensuring a secure and stable connection for structural components and accessories. While they are highly durable and rust-resistant, users should verify that their specific greenhouse model uses standard 11mm shaft length fixings to ensure full compatibility before beginning larger assembly projects.

FAQs
Will these fit a wooden greenhouse?
No, these are specifically designed for aluminum-framed greenhouses with standardized glazing channels.
Can I use these to replace existing bolts?
Yes, as long as your current frame utilizes standard glazing channels and requires an M6 thread size.
Do I need a special tool to install them?
No special tools are required, though a small socket or adjustable wrench is helpful for final tightening.
Are these bolts made of stainless steel?
The bolts are designed to be rust-resistant and suitable for outdoor greenhouse conditions.
What is the length of the bolt shaft?
The shaft length is 11mm, which is the standard size for most aluminum greenhouse profiles.
Troubleshooting
Bolt spins inside the glazing channel instead of tightening.
Ensure the bolt head is correctly oriented 90 degrees to the channel track so the square sides lock against the inner walls.
Nut is difficult to tighten by hand.
Check the threads for any aluminum shavings or debris from the channel; clean the threads and use a small wrench to provide initial torque.
Pros and Cons
Pros
- Resistant to rust and weathering
- Universal fit for standard aluminum channels
- Easy installation without needing specialized tools
- Large pack size provides great value for multiple projects
Cons
- May not fit non-standard or proprietary greenhouse framing systems
- Requires manual tightening which can be time-consuming on large projects
- Not suitable for heavy-duty load-bearing tasks beyond greenhouse structures
Setup, Compatibility & Care
To install, simply slide the head of the bolt into the glazing channel at the desired location. Once inserted, rotate it slightly until the square shoulders sit flush within the channel. Attach your bracket or panel, then hand-tighten the matching nut. While these bolts are rust-resistant, it is recommended to apply a light lubricant to the threads if you live in coastal areas with high salt content in the air. Periodically check the tightness of the nuts after strong wind storms, as vibrations can occasionally loosen hardware over time.
