Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive torque on nylon fasteners.Apply torque incrementally and refer to material-specific torque charts for nylon to prevent thread stripping or component damage.
Exposing nylon fasteners to extreme UV radiation or high temperatures beyond their rated limits.Ensure the application environment is within the specified operational temperature range and consider UV-resistant nylon grades if prolonged outdoor exposure is expected.

Common Applications
