“Growermetal confirms its role as a forward-thinking company in the fastener industry and unveiled a new addition to its branded product range: the Grower Econical® washer, aimed at redefining the conical washer concept, combining mechanical efficiency with sustainability”.
Torque, an international magazine for the global fixing, fastener, hand, and power tool, reports on Growermetal’s achievements in terms of innovation.
In March 2025, the new design won The Route to Fastener Innovation, a competition focused on fastener companies.
Grower’s Econical® technology is an evolution of the conical washers DIN 6796 and NFE 25510: its sigmoidal geometry improves performance and reduces material usage.
The 20% reduction in product weight, the more than 25% increase in spring force, and the 15% improvement in residual deflection and elastic recovery ensure reliability and high performance.
