💡 Pro Tips
❌ Common Mistakes to Avoid
🔍 Troubleshooting
Fasteners keep loosening
*Cause:* Vibration or insufficient preload
*Fix:* Use lock washers, thread locker, or increase bolt grade
Threads strip easily
*Cause:* Wrong pitch, cross-threading, or overtightening
*Fix:* Use thread gauge, start by hand, use proper torque
Corrosion at fastener locations
*Cause:* Dissimilar metals or inadequate coating
*Fix:* Use compatible materials, apply anti-seize, choose better coating
