Pierce Nut Wire

Bekaert pierce nut wires are work-hardened steel profiles with custom-made grooves for the attachment of the nuts to sheet metal during the stamping process. Fastener manufacturers produce pierce nuts from continuous coils of these pre-shaped wires. Pierce nuts become integral fastening points to join metal panels together, or for mounting subsequent parts to the panels. Pierce nuts offer a durable and reliable fastening method for mass-produced parts and products, resisting torque, shear loads, vibration and tension.
