PEM® Spotfast® Stainless Self-Clinching Fasteners

PEM® Spotfast® Stainless Self-Clinching Fasteners resist corrosion in flush-mount applications.

New PEM® SpotFast® stainless steel self-clinching fasteners ideally suit flush-mount attachment applications where corrosion resistance may be required. These fasteners permanently join two metal sheets to create a flush-attachment connection without protrusions on either side and can serve as practical alternatives for rivets or welding. Their rotational capability extends application potential by enabling a single fastener to act as a hardened pivot point.

The fasteners (Type SFP) are made from precipitation hardened stainless steel and can be installed in stainless steel sheets as thin as .030”/0.8mm with hardness of 88 or less on the Rockwell “B” scale. They join a growing family of uniquely engineered SpotFast hardware.

Fasteners install smooth with the top sheet and flush, sub-flush, or blind with the bottom sheet. They can attach two metal sheets too thin to weld; fasten sheets of unequal thicknesses; or join dissimilar metals unable to be welded. When used as a pivot point, the top sheet is effectively captivated between the head of the fastener and the lower (non-rotating) sheet. The top sheet then is able to rotate freely.
Unlike rivets that “bulb” during installation, the flush profile upon their installation 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.

SpotFast fasteners are RoHS-compliant and available in various head diameters and sizes.
