Use Instruction

跳过导航链接XINKAI > SUPPORT > Product Use Instruction

 
DO:  
  • Provide mounting hole of specified size for each fastener.
  • Make certain that shank (or pilot) is within hole before applying installation force.
  • Apply squeezing force between parallel surfaces.
  • Apply sufficient force to totally embed clinching ring around entire circumference and to bring shoulder squarely in contact with sheet. For some fasteners, installation will be complete when the head is flush with the panel surface.
  
 DON‘T  
  • Install steel or stainless steel fasteners in aluminum panels before anodizing or finishing.
  • Deburr mounting holes on either side of sheet before installing fasteners – deburring will remove metal required for clinching fastener into sheet.
  • Install fastener closer to edge of sheet than minimum edge distance indicated by manufacturer – unless a special fixture is used to restrict bulging of sheet edge.
  • Over-squeeze. It will crush the head, distort threads and buckle the sheet. Be certain to determine optimum installation force by test prior to production runs.
  • Attempt to insert fastener with a hammer blow under any circumstances. A hammer blow won't permit the sheet metal to flow and develop an interlock with the fastener's contour.
  • Install screw in the head side of fastener. Install from opposite side so that the fastener load is toward sheet. The clinching force is designed only to hold the fastener during handling and to resist torque during assembly.
  • Install fastener on pre-painted side of panel.
