WASHER (P/N din137b5phr) - New

The din137b5phr is a DIN 137 Form B wave spring washer manufactured from spring steel. This corrugated washer maintains preload in bolted joints by providing elastic deflection under compression. Installed under bolt heads or nuts in confined spaces, it compensates for vibration and thermal cycling that would otherwise loosen fasteners.

Commonly used in aircraft equipment mounts, structural attachments, and control system assemblies where space constraints prevent traditional lock washers. Spring steel construction allows repeated deflection without permanent deformation, ensuring sustained clamping force throughout service life.
