Growermetal adds spherical washers and conical seats 13 January 2020

Growermetal Srl has added two new articles to its standard production range during 2019 – spherical washers (type C) and conical seats (type D) – both manufactured in compliance with the German standard DIN 6319.

The spherical washer, used in combination with the conical seat, guarantees a safe locking function on non-parallel bearing surfaces – when the hole and bolt are not perfectly aligned. Working together, the spherical washer and conical seat compensate each other to a maximum of 3 degrees.

The washers are available in case hardened carbon steel with a surface hardness of 550HV – 650HV 10. The range of dimensions includes M6 up to M48.

The washers are available with different surface treatments including burnishing with light oil film protection, phosphating, and others on request such as mechanical zinc plating, as well as zinc flake coating processes – all carried out in-house.
