Washers are generally designed to distribute the pressure of the bolt and nut over the part being secured, reducing the risk of damaging it.
The high-tech Growermetal’s safety washers offer many additional features such as high resistance to loosening in presence of vibrations, dynamic loads, heat, temperature variations and other external factors and are also designed for oversized or oval holes.
The working principle of Growermetal’s safety washers to secure the bolted joint connection can be either based on friction or tension.
