Rondella elastica 8 De Dietrich 7632798

The spring washer 8 is a small but vital component for preventing loosening of bolted connections in heating equipment. Designed to fit m8 bolts, this washer applies constant tension to maintain clamping force under vibration and thermal expansion. In boiler and burner assemblies, where components are subject to heat and movement, using a spring washer helps ensure that fasteners stay tight over time. It is an inexpensive yet effective addition to any maintenance kit for gas burner parts or boiler spare parts, contributing to the overall reliability and safety of the system.
