PEM announced the type SFP self-clinching fasteners which are suited for 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. They are made from precipitation hardened stainless steel and can be installed in stainless steel sheets as thin as .030”/0.8 mm with hardness of 88 or less on the Rockwell “B” scale. They install smooth with the top sheet and flush, sub-flush, or blind with the bottom sheet and 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.
