DIN 127 washers, also known as Grower washers, are helical spring washers designed to reduce the risk of loosening in bolted joints. Their spiral shape generates additional pressure after tightening, increasing friction between the bolt head or nut and the bearing surface.
They are used in assemblies subject to vibration, impact or load cycles, where a flat washer is not sufficient to maintain the tightening tension. They are commonly used in machinery, metalwork, industrial equipment and general fastenings with medium requirements.
DIN 127 washers: elastic locking for screw connections
At CHAVESBAO we offer DIN 127 Grower washers made of steel and stainless steel, with zinc-plated versions for indoor applications and A2 and A4 stainless steel for outdoor assemblies or humid or corrosive environments. This range allows the washer to be adapted to the service conditions and the type of fasteners used. Their helical design provides an elastic effect that helps maintain the tension of the joint in the face of moderate vibrations. They are recommended as a complement to metric screws and nuts in mechanical fastenings where a simple solution is sought to reduce the risk of premature loosening.
