Strategies for Preventing Thread Galling
Galling occurs when friction causes threads to seize, a common issue with stainless steel fasteners that can be prevented with lubricants.
Understanding the application
Galling is adhesive wear that can cause mating threads to seize, particularly with some stainless combinations and assembly conditions.
Selection & technical considerations
Clean threads, suitable material pairing and an approved lubricant may help reduce the risk. Lubrication changes must be reflected in the tightening specification.
Practical checks before use
Stop if abnormal resistance occurs. Forcing a seized thread can damage the fastener and joint; inspect and replace parts according to the repair procedure.
