Blind Rivet with Large Flange

The blind rivet with large flange is used for permanent joining of metal sheets and serves as an alternative to welded joints where there is single-sided access to the joint.

The thickness of the joined metal ranges from 1.5 to 35 mm depending on the mandrel length and flange diameter. The rivet is securely fixed in the hole.

The material varies. The body can be made of copper, aluminium, or steel; the mandrel — of aluminium, stainless steel, or zinc-plated stainless steel. Such products are in demand in mechanical engineering and other industries.
