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.
