What is the required installation torque? What are the effects of being too tight or too loose?
Thread Locking Core Principle
- Torque-Controlled Operation : Standard torque for thread locking ensures reliable contact, structural integrity and protection performance, avoiding risks from over-loose or over-tight operation.
Thread Locking Specifications & Risks
Recommended Torque Specification
Standard Torque
:
• Recommended locking torque: 1.2–1.5N·m
• Operation method: Hand-tightened + 1/4 turn
• Ensures optimal contact and sealing effect
Operation Risks
Over-Loose Risks
:
• Poor contact, vibration loosening, protection failure
Over-Tight Risks
:
• Thread damage, O-ring crushing, water ingress/short circuit
Technical Note: Use a torque wrench to control the locking force accurately, and avoid brute force operation. This is critical to ensure the long-term reliability of the connector in industrial environments.
