PierceForm Stud Specs

CP Series PierceForm Studs are property class 9.8 system-fed fasteners that pierce their own hole in a metal panel.Designed specifically for metal stamping applications, these fasteners make a consistent mechanical attachment which provides a secure, sealed, permanent installation. Because CP Series PierceForm Studs can be installed in the same die that forms the part, they offer many advantages over conventional fasteners.

Note: Standard end configuration is the Header Point. Standard stud lengths (L) are: 16, 20, 24, and 30mm. For applications where other end configurations or lengths are required, consult your sales representative.
