Corrosion – Avoid contact with moisture: Fastening components should be protected from prolonged exposure to moisture or aggressive chemicals that can cause corrosion.

Use of protective coatings – Ensure that the components are protected with an anti-corrosion coating suitable for the operating environment (e.g., galvanizing, epoxy coatings). Regular maintenance: Inspect components for signs of corrosion and replace them as needed.

Mechanical damage – Do not exceed the maximum tightening torque: Over-tightening can damage the thread or weaken the fastening components. Use tools with the correct torque rating.

Avoid dynamic loads beyond specifications – Bolts and screws should be used according to their intended purpose, especially in applications exposed to vibrations or impacts.

Pre-use inspection – Before installation, check components for deformation, cracks, or other damage.

Improper use – Ensure you are using fastening components of the correct size, material, and strength class for the given application.

Do not use damaged components – Bolts, screws, and washers with visible mechanical damage or corrosion should be immediately replaced.

Avoid improper assembly – Ensure proper alignment and compression to avoid stresses in the fastening material.

Use of appropriate tools – Use tools that meet specifications for assembly and disassembly (e.g., torque wrenches).
