Key Considerations When Purchasing Your Fixing Nuts
Environment
Make sure the nuts you purchase are suitable for the environment in which you will install them. For example, some metals cannot be used in food production environments, and stainless steel should be used instead.
Thread
Ensure you are purchasing the right thread,metric is most common (and the standard in almost all applications).
Size
Ensure you are buying the right size nut for your associated fixing. Nuts are almost always measured by their internal diameter.
Application
Do you need something with high tensile strength or with specialist features such as a nyloc insert to prevent it from coming undone with vibrations
Coatings
Consider what coating would be best suited to your use case. Options can include hot-dip galvanised and BZP, to name just a couple.
Material
Will the nuts be installed in a marine environment or somewhere stainless steel is required? Ensure both your nuts and bolts share a common material type to avoid bi-metallic corrosion.
