FAQs
What material are these bolts and nuts made from?
They are constructed from durable carbon steel with a zinc-plated finish.
What is the diameter and length of these fasteners?
The diameter is M5, and the length is 20mm.
Are these suitable for outdoor use?
They offer some corrosion resistance due to zinc plating but are best suited for dry conditions. Prolonged exposure to moisture or outdoor elements may lead to rust.
What tools do I need to use these?
You will need a wrench or socket that fits a standard M5 hex head, typically 8mm or 10mm depending on the specific nut design.
Can I use these for structural applications?
These fasteners are designed for general DIY and repair tasks, not for heavy-duty structural applications where higher strength or specific corrosion resistance is required.
How many bolts and nuts are in a pack?
Each pack contains 10 bolts and 10 nuts.
Troubleshooting
Bolt won't thread smoothly into nut.
Ensure you are using an M5 bolt with an M5 nut. Check for any dirt or debris in the threads. Try a small amount of lubricant if resistance is high. Do not force the bolt, as this can damage the threads.
Nut is difficult to tighten.
Verify the bolt length is sufficient for the materials being joined. Ensure the nut is seated correctly on the bolt threads and not cross-threaded. Use an appropriate wrench or socket for firm, even pressure.
Bolt head strips during tightening.
Use the correct size wrench or socket that fits snugly on the hex head. Apply steady, even pressure. If the head starts to strip, stop immediately and try to remove the bolt with pliers if necessary.
Signs of rust appearing.
This indicates the zinc plating may be compromised. Clean the rusted area with a wire brush and apply a rust-inhibiting coating or a thin layer of oil to prevent further corrosion. Consider replacing the fastener if rust is extensive.

- Hex head allows for easy tool engagement.
- Cost-effective pack for DIYers.
Cons
- Zinc plating may not suffice in harsh, corrosive environments.
- Carbon steel can rust if plating is compromised.
- Limited length may not be suitable for thick materials.
- Not designed for heavy-duty structural applications.
Setup, Compatibility & Care
Setup: These bolts and nuts require no special setup. Simply insert the bolt through the desired holes and secure it with a nut. Ensure the M5 threads align correctly for a smooth connection.
Compatibility: The M5 diameter is a standard metric thread size, compatible with other M5 bolts, nuts, and pre-drilled holes of the same specification. They are generally suitable for use with wood, plastic, and metal components where an M5 fastener is appropriate.
Care: To maintain the integrity of the zinc plating and prevent corrosion, store these fasteners in a dry environment. Avoid exposing them to excessive moisture or salt. If they become dirty, clean them with a dry or slightly damp cloth. For long-term storage, consider using a rust inhibitor spray if they will be kept in a potentially humid area.
