Essential Roof Tent Spare Kits for UK Trips
Share
A missing fixing bolt is a small problem at home. At a wet campsite, with your roof tent partly opened and the nearest hardware shop miles away, it can end the trip early. Essential roof tent spare kits are not about carrying a garage-full of parts. They are about having the few roof tent-specific items that let you secure, repair and continue travelling safely.
For TentBox, OEX and compatible rooftop tent owners, the best kit is built around the fittings actually holding your tent to the vehicle. Generic camping spares are useful for a broken guy line or a torch battery, but they will not help if a mounting plate, rail bolt or locking nut goes missing.
Why essential roof tent spare kits matter
A roof tent is exposed to vibration, weather, road grime and repeated opening cycles. Most owners will never experience a serious failure, particularly where the tent has been fitted correctly and checked regularly. But small components can be misplaced during removal, damaged by cross-threading or become difficult to reuse after years of road salt and seasonal trips.
The consequences are different from a problem with a ground tent. Your roof tent is mounted above your vehicle, often with specific rails, brackets and hardware. If the mounting system cannot be tightened correctly, the sensible decision may be to stop using the tent until it is repaired. A spare kit gives you options before a minor issue becomes a recovery problem.
There is also a security reason to carry the right parts. Anti-theft hardware can make a roof tent far less attractive to opportunist thieves, but it needs to remain properly fitted. Losing the key or tool for a locking fixing, or discovering a nut is damaged while away, is frustrating at best. A planned kit helps you maintain the protection you paid for.
Start with the mounting system on your own tent
Do not buy spare hardware based only on a product photo or a similar-looking roof tent. Rail profiles, bolt lengths, thread sizes, bracket shapes and access requirements vary between models and mounting setups. Even tents from the same manufacturer can use different arrangements depending on their age, shell type, roof bars or rack.
Before building a kit, take a clear photograph of each mounting point. Note the bolt diameter and thread pitch, the length of the bolt, the washer arrangement and the style of plate or bracket used beneath the bars. Keep that information with your vehicle documents or on your phone. It makes reordering far easier if a fitting is lost at a campsite.
Check whether your tent is attached directly to approved roof bars, a platform rack or another vehicle-specific system. The spare parts must suit the whole installation, not just the tent rails. A bolt that fits through a rail may still be too short for a thicker rack, while a longer bolt may bottom out or leave too much exposed thread.
Spare bolts, washers and plates
A small matched set of mounting bolts, washers and nuts is the foundation of most roof tent spare kits. Carry them together in a labelled pouch rather than mixing them with random vehicle fixings. The correct washers spread load and protect the mounting surface, so they are not an optional extra.
If your setup uses sliding plates inside the tent rail, keep at least one compatible spare plate. These are easy to misplace when removing a tent or changing vehicles. They are also one of the parts that cannot be reliably improvised with a standard bolt from a petrol station shop.
Do not assume any stainless steel fastener is automatically suitable. Material grade, thread type and size matter, as does compatibility with the manufacturer’s mounting method. If a bolt is bent, heavily corroded or the thread has started to strip, replace it rather than trying to make it last for another season.
Locking nuts and the correct removal tool
For many owners, locking nuts are the most valuable item in the kit because they protect a costly tent where it is most vulnerable: parked on the drive, outside a hotel or at a trailhead. Tamperproof hardware is a deterrent, not a reason to stop being careful about where you park, but it adds a meaningful barrier to quick removal.
Carry the correct removal socket, key or specialised tool separately from the vehicle keys. If it is always on the keyring, losing one item could leave you unable to remove your own tent. It is sensible to keep a spare tool in a secure place at home too.
A spare locking nut set is useful when a nut becomes rounded, seized or damaged. However, security nuts still need to be tightened to the appropriate setting. Overtightening can damage threads or deform components, while undertightening can allow movement. If you do not have the right tool or are unsure about the condition of the mounting hardware, do not guess.
Replacement rails and rail hardware
Rails are not the first spare most people think of, but they are worth considering if you travel frequently, remove your tent between trips or have an older setup. A damaged rail can affect how the tent sits on the bars and how securely the mounting plates locate.
A full replacement rail is usually more of a home or workshop spare than something to carry on every weekend away. It is longer, less convenient to pack and may require a careful installation rather than a roadside repair. Still, knowing the correct replacement rail for your tent can save time when damage is found after loading, fitting or storage.
For long-distance touring, inspect the rails before departure for dents, cracks around fixing points and loose hardware. Any damage that affects the tent’s secure attachment deserves attention before you set off.
What to keep in the vehicle
Your travel kit should be compact, dry and easy to identify. A waterproof tool pouch stored with your camping kit is generally better than leaving small metal parts loose in the boot. The aim is to solve predictable issues without adding unnecessary weight.
A practical kit will usually include:
- A matched spare set of compatible mounting bolts, washers, nuts and any sliding plates used by your tent.
- The socket, key or specialist tool required for your locking or tamperproof nuts.
- A spare locking nut or complete compatible locking set where security hardware is fitted.
- A suitable socket set, ratchet and extension for accessing the mounting points safely.
- A small torque wrench where you know the required setting, plus gloves and a cloth for cleaning threads.
- Spare batteries if you use a roof tent alarm, along with any fitting hardware specific to its holder.
Check the tent before problems start
Spare parts are useful, but inspection prevents more issues than any pouch of hardware. Check the mounting points after a new installation, after the first proper drive, and before every longer trip. Look for movement at the rails, missing washers, rust, damaged threads and signs that a bracket has shifted.
Pay attention after driving on rough tracks, carrying the tent through winter or fitting it to a new vehicle. Road vibration can reveal an installation issue that was not obvious on the driveway. If you hear a new rattle from above, investigate it before the next journey rather than turning the radio up.
Security products should be checked at the same time. Make sure locking nuts are present, alarm units are charged or powered as intended, and deterrent stickers remain visible and clean. An alarm is most useful when it is correctly positioned and tested, not when its battery has quietly gone flat in the rain.
Roof Tent Security supplies roof tent-specific security and fixing products because compatibility is the detail that matters here. A general-purpose fastener may look close enough, but a correctly matched component gives you more confidence when your accommodation is travelling at motorway speed above your roof.
Know when a spare is not the answer
There is a clear line between replacing a lost washer and repairing a damaged mounting system. Do not use a spare kit to work around cracked rails, distorted roof bars, damaged rack feet, a compromised vehicle roof or a tent shell that no longer sits correctly. These faults need proper assessment before the tent is used again.
The same applies if you cannot confirm the correct bolt length, thread or tightening requirement. Stopping for a night in a campsite is inconvenient; risking the tent, vehicle or other road users is not worth it. A mobile fitting specialist can be particularly useful when a replacement tent is being installed, a fitting setup needs checking, or you are not confident working at roof height.
Build your kit around your exact tent, inspect the installation before each trip and replace tired hardware early. Then the spare parts stay where they should be: packed away, ready for the moment they save a good weekend from becoming an expensive one.
