Part Design Guidelines

PierceForm CP Studs are property class 9.8 and act as their own punch to become rigidly and permanently attached to a metal panel within the same die used to form the part and stud, thereby offering many advantages over conventional fasteners.  PierceForm CP Studs make a consistent mechanical attachment which provides a secure, permanent installation; standard stud lengths are 16, 20, 25 and 30mm; standard end configurations are the header and ISO short dog point.  PierceForm CP Studs may be installed in almost any panel material, of almost any shape, and in almost any multiple-pattern configuration, within the constraints shown below.  However, if you have a unique application not covered here, give us a call.  We will help work out a solution with you.

Application in Special Materials

For HSLA, stainless steel, aluminum, and/or plastic material, consult your representative.

Select Proper Stud

Select according to tables found on PierceForm CP Stud specifications sheet.

Simulpiercing Two Sheets of Metal
(PierceForm Studs Only).

Total panel thickness not to exceed 90%of recommended thickness for PierceForm Stud metal range.  For other panel materials, contact your representative.

Sealing Applications

Sealing is attained as an integral feature of the installation process.  Consult your representative for further details.

Critical Applications

When extreme torque, stress, or environmental requirements exist, consult your representative prior to specifying PierceForm CP Studs.

Accuracy of Location
(PierceForm Studs Only)

In multiple stud installations the location of one stud to another will be within a diametral tolerance of 0.4mm.

When a Forming Operation Follows a Stud Operation

Do not form part closer than 10.0mm after PierceForm CP Stud is installed, as shown.  For closer spacing requirements, consult your representative.

Stud Edge to Panel Edge Distance

Studs must not be installed closer to the edge of a panel than twice the thickness of the metal panel, as shown.

Minimum Stud Spacing (With Standard Head Installation Tooling, Retainers May Require Alteration)

NOTE:  Closer stud-to-stud distances may be achieved using altered standard and/or special tooling.  Consult your representative.

Stud to Flange Distances (With Standard Installation Tooling)

Closer stud-to-flange distances may be achieved using altered standard and/or special tooling.  Consult your representative.
