Product Details
PEMSERT® self-clinching flush nuts suit applications where a thin metal sheet requires load-bearing threads stronger than tapped holes but must remain flat without any protrusions on either side of the sheet.  They can be installed before sheet bending and forming to provide threads for mating hardware in sections that otherwise would be inaccessible for fastener installation after chassis are formed.  Their uniquely designed hexagonal head and clinch technology ensures high axial and torsional strength in service.  The nuts install permanently, will not loosen or fall out, and leave surfaces unmarred to enhance the cosmetic qualities of assemblies. 
  
The range includes PEMSERT F™ 300 Series stainless steel types for installation into steel or aluminium sheets and PEMSERT F4™ heat-treated 400 Series stainless steel versions specifically designed for installation into 300 Series stainless steel sheets.  Both types are available in thread sizes 2-56 to ¼-20 and M2 to M6.  Sheets can be as thin as .060”/1.53mm.  For aerospace applications, F nuts can also be ordered to conform with US NASM45938/4 aerospace standards. 
  
Installation is accomplished easily by squeezing the nut into a round hole using sufficient force to embed its hexagonal head flush in the sheet.  The metal displaced by the head then flows evenly around the back-tapered shank of the fastener to securely lock the nut permanently into place.  Both the hexagonal head and the fastener’s self-clinching design combine to deliver high pullout and torque out resistances.  Only a mating screw is required to complete the final component attachment.
