Product Information
Full details
This pack of 10 Diall M8 hex bolts and nuts is designed for DIY enthusiasts and general repair tasks requiring secure fastening. The key benefit is the durable carbon steel construction providing reliable strength for various projects. A potential caveat is that these are zinc plated, which offers some corrosion resistance but may not be suitable for extremely harsh or continuously wet environments without additional protection. This set includes 10 M8 bolts and matching nuts, each 20mm in length, offering a convenient quantity for common applications.

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 the bolts?
The bolts have an M8 diameter and are 20mm in length.
Are these suitable for outdoor use?
The zinc plating offers some corrosion resistance, making them suitable for sheltered outdoor use. For prolonged exposure to weather, additional protective measures or specialized hardware may be necessary.
How many bolts and nuts are included in the pack?
The pack contains 10 M8 bolts and 10 matching M8 nuts.
Can I use these for structural or load-bearing applications?
These are intended for general DIY and repair tasks. For heavy-duty structural applications, it is recommended to consult with an engineering professional to ensure appropriate hardware is selected.
How should I store these fasteners?
Store them in a cool, dry place away from moisture to prevent corrosion and maintain the integrity of the zinc plating.
Troubleshooting
Bolt won't thread smoothly into the nut.
Check for any damage to the bolt threads or nut threads. Ensure you are using the correct M8 size and that no debris is present. Try backing the bolt out and re-threading gently.
Nut feels loose after tightening.
Ensure the bolt is long enough to engage fully with the nut. Check if the bolt or nut threads are damaged. Consider using a locking washer or thread-locking compound for extra security if the application permits.
Signs of rust or corrosion.
This indicates the zinc plating may be compromised or the environment is too harsh. For continued use, clean the affected area and apply a rust inhibitor or appropriate protective coating. For critical applications, replace with more robust hardware.
Pros and Cons

- Convenient pack size for common DIY tasks.
- Standard M8 size offers broad compatibility.

Setup, Compatibility & Care
Setup: These bolts and nuts are ready for immediate use. Simply thread the bolt through the materials you wish to join and secure it with the corresponding M8 nut. Ensure the bolt length is appropriate for the combined thickness of the materials plus the nut's thickness.
Compatibility: The M8 diameter is a standard metric size, compatible with other M8 hardware, tools, and components. They are suitable for use with wood, plastic, and metal materials where an M8 thread is appropriate.
Care: To maintain the integrity of the zinc plating and prevent corrosion, store the bolts and nuts in a dry environment. Avoid prolonged exposure to moisture or salt. If used in damp conditions, consider applying a sealant or grease to the threads and exterior for added protection. Wipe clean with a dry cloth if they become dusty.
