Part Design Guidelines

The PierceForm ® RSK Nut is a property class 9.8 automatically installed, system-fed fastener that does not require a pre-pierced hole. Offered by Multifastener, the PierceForm RSK Nut makes a consistent mechanical attachment which provides a secure, permanent installation. The PierceForm RSK Nut can be installed in the same die used to form the part, thereby offering many advantages over conventional fasteners. Many metal panel thicknesses and shapes will make excellent installations; however, the metal panel and configuration are critical to obtaining a good installation. If aspects of your application are not covered here, please contact your Multifastener representative.
