The Avdel® Avdelmate® rivet is a two-piece wide-grip, breakstem fastener suitable for a range of applications in soft, thin sheet, and brittle materials.
This two-piece breakstem fastener consists of a rivet and tubular section. Upon insertion, the rivet stem is retained in the tubular component, avoiding loose stems.
Avdelmate® fasteners provide a secure clamp without crushing the parent material and good hole fill due to the radially expanded rivet body. This makes the Avdelmate® fastener ideal for stadium seating, furniture, playground equipment, street signs, and racking applications.
