Installation and Precautions
- Stainless steel threads are prone to cold welding; it is recommended to apply anti-seize compound.
- Control the torque to avoid over-tightening, which can cause the threads to strip.
- Avoid mixing with carbon steel to prevent electrochemical corrosion.
- Store in a dry place and avoid scratching the passivation layer.
