Self Clinching Blind-Threaded Fasteners
Machined parts generally use blind-hole PEM® brand self-clinching fasteners (whereas sheet metal is
generally used with through-hole PEM® brand self-clinching fasteners).
Inserting PEM® brand self-clinching fasteners into blind holes has the extra benefit of a smooth
finish on the opposite sides of sheet metal after the fastener is installed. These PEMS® can be used
in sheet metal as thin as 0.075" (1.90mm).
Concealed fasteners for blind features are ideal when:
- • Outside surface finish is important
- • Metal is too thick for other stocked PEM® brand self-clinching fasteners
- • Where protecting from air, liquid, or dust is extremely important
Protocase stocks the following PEM® brand self-clinching fasteners for blind milled holes:
