Recommendations for installing stainless steel studs in stainless panels when greater corrosion resistance is desired and applications that may be exposed to high heat:

At one time the only option for a designer when they wanted to install stainless steel studs in stainless panels was to utilize stainless steel weld studs. However the cosmetic result was often not desirable. Due to the higher hardness of the cold worked stainless steel panels, Captive Fastener now provides a stainless steel flush head clinch stud made with precipitation hardened and passivated type A286 series stainless steel. The result is a fastener that is hardened and is able to be installed into panels with a maximum hardness of up to HRB 92. This product is our CH2S series studs made specifically to be installed into stainless steel panels which may be exposed to a corrosive environment. The CH2S series studs also provide excellent performance in high temperature applications such as warming trays and ovens along with many other uses. The CH2S studs provide the head of the fastener that is flush with the panel into which it is installed. This offers a strong load bearing thread that allows for installation of the mating fastener without the need to access both sides of the panel.
 

Installation of Self-Clinching Studs in Stainless Steel Panels

When installing a stainless clinch stud in stainless panels that may be exposed to a corrosive environment, the proper selection would be  the CH2S series stud depending on the application and desired performance values for the particular design. Due to the higher hardness of the stainless steel panels the installation of the studs requires greater force than the force required to install a clinch stud in steel or aluminum material. For example to install a ¼-20 CH2S stud into a stainless steel panel the installation force required to properly seat the fastener is approximately 13,000 lbs. The recommended installation force for each thread is spelled out in the installation and performance section of our catalog.

Sheet Metal Studs Performance Values - Series CH2S

The push out and torque out values are listed in our catalog under the heading Installation and Performance Data.  For example if a ¼-20 CH2S stud is properly installed into a stainless steel panel the push out value will be approximately 1,590 lbs. and the torque out value will be approximately 154 inch lbs. These self clinching studs provide a low cost of installation coupled with excellent performance values and an appealing cosmetic appearance. They also eliminate loose hardware which is always desirable particularly in electronic enclosures and cabinets.
 
CH2S studs are available in both inch and metric threads and are REACH and RoHS compliant. If 2D or 3D prints are required they are available on our product pages within the website.
