Installation / Usage Tips
• Torque: Apply moderate torque (do not over-tighten) to prevent thread damage on your spacer screw.
• Anti-loosening: Use thread-locking adhesive (Loctite) or nylon-insert lock nuts for vibration-prone applications.
• Safety: Ensure the standoff bolt length matches your panel thickness for secure clamping. Refer to our PCB mounting guide for detailed instructions.
