F-256-1 PEM

PEM self-clinching flush nuts are flush with both sides of the sheet. F PEMSERT SELF-CLINCHING FASTENERSPEMSERT SELF-CLINCHING FLUSH FASTENERS PEMSERT self-clinching flush nuts are designed to be installed into sheets as thin as .060/1.5 mm. F and F4 fasteners are ideal for applications where a thin sheet requires threads stronger than a tapped hole but still must remain flat, with no protrusions on either surface, enhancing the functional and cosmetic qualities of the entire assembly. PEMSERT flush nuts are installed easily by squeezing them into a round hole in metal sheets. They can be installed before bending and forming to provide threads in places which would be inaccessible for installation after chassis are formed. The hexagonal head along with the proven PEM self-clinching design ensures high axial and torsional strength. F4 flush nuts are specifically designed to be installed into stainless steel sheets. PEMSERT F fasteners can be ordered to conform to US NASM45938/4 specifications.* *To meet national aerospace standards and to obtain testing documentation, product must be ordered to NASM45938/4 specifications.
