PEM® SpotFast® Fasteners: Flush, Strong Sheet-to-Sheet Attachment for Server Applications
PEM® SpotFast® fasteners provide a flush, reliable method for permanently joining two sheets of metal without protrusions—making them highly effective for server enclosures, chassis frames, and internal assemblies where flush surfaces and compact design are essential.
- Attach two metal sheets too difficult to weld
- Fasten sheets of unequal thicknesses
- Join dissimilar metals unable to be welded
- Attach ultra-thin metal sections
- Attach metal to PCB, plastic or cast metals
- RoHS compliant
Unlike rivets that “bulb” during installation, the ultimately flush profile of SpotFast® fasteners allows for unobtrusive attachment requiring minimal space. A smooth surface is retained for finishing and fasteners can be concealed easily with paints or powder coatings.
Optimized for Server Environments:
- Flush, Permanent Attachment: SpotFast® fasteners join dissimilar (such as steel to aluminum) or same-material sheets with no protrusion on either side—ideal for maintaining airflow paths and tight packaging in server racks.
- Space-Saving Design: Allows for low-profile, secure joints without welds, screws, or rivets—reducing internal clutter and improving access for cable routing and component layout.
- High Strength with Minimal Distortion: Provides high holding strength without thermal distortion, making it suitable for precision electronics housings and thermal management panels.
- No Secondary Operations Required: Installed using standard press equipment with a single-step process, improving manufacturing efficiency and repeatability.
- Supports Mixed Material Use: Perfect for combining lightweight aluminum panels with stronger steel frames in server housings to optimize strength-to-weight ratio.
Key Applications in Server Systems:
- Joining internal sheet metal structures in chassis or enclosures
- Mounting panels and brackets inside server racks
- Securing thermal shields or EMI enclosures
- Replacing spot welds and rivets in multi-material assemblies
