Pierce Nut Wire

Pierce nut wires from Bekaert consist of work-hardened steel profiles with custom-made grooves used for attaching nuts to sheet metal during metal stamping. Fastener manufacturers worldwide utilize our continuous coils of pre-shaped wires to produce pierce nuts. 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. Bekaert can provide continuous coils of pre-shaped pierce nut profiles up to 4,400 pounds or 2 metric tons.

Steel Pierce Nut Wire Applications

Bekaert's steel pierce nut wire is the core component in manufacturing pierce nuts — also called self-piercing nuts or self-clinching nuts. These nuts install into sheet metal to form a threaded hole used for various fastening applications across a comprehensive industry range, including automotive and exterior products

Pierce nuts are among the most popular fasteners for sheet metal because they are self-piercing, meaning they do not need a pilot or pre-punched hole for installation. Also, since their installation eliminates the fumes and sparks associated with weld-nut assembly, pierce nuts are an eco-friendly fastening option. 

Several examples of applications for pierce nuts include:

  • Automotive body panels.
  • Interior components, including seating, door panels and ingress protection (IP).
  • Engine compartments.
  • Appliances and white goods.
  • Lawn and garden equipment.
  • Agricultural products.
  • Other industrial applications.
