Spring pin 20mm (10 ps) De Dietrich S101131

A spring pin of 20mm length is a simple yet essential fastener used in various mechanical assemblies within boilers and burners. Spring pins, also known as roll pins, are designed to absorb shock and vibration while providing a secure connection between components. They are commonly used to align parts or as pivot points in linkages. Over time, these pins can wear or break, leading to loose connections or misalignment. Replacing a worn spring pin restores proper function and prevents further damage. This 20mm pin is a common size for many heating equipment applications, making it a useful spare part for repairs.
