Stock / Supplier search Send your request for quotation

Countersunk head rivets with nominal diameters from 1 to 8 mm

This standard (DIN 661) applies to countersunk head rivets with nominal diameters from 1 mm to 8 mm. The setting of solid rivets is achieved by passing the rivet through the material to be fixed and then either deforming the end of the shank or fitting a non return washer. Deformation can be achieved by hammering or using a press or spin riveting.
