💡 Pro Tips
- Confirm the bolt diameter, thread pitch, and nut size before installation.
- Start threading by hand to reduce the risk of cross-threading.
- Tighten with the correct tool and avoid excessive force that may damage the threads.
- For damp locations, keep the hardware clean and dry and consider suitable corrosion protection.
- Do not use for safety-critical or structural applications unless the hardware has been properly rated for that purpose.
