Self Clinching Nuts

Self-clinching fasteners and self clinching nuts (the equivalent of PEM® Nuts) are threaded devices that provides a permanent anchor by swaging the material that surrounds it. Clinch nut installation is achieved when the self clinching nut is pressed into ductile metal, which displaces the host material around the mounting hole, causing it to cold flow into a specially designed annular recess in the shank pilot of the fastener. 
Monroe-JHP Fasteners maintains a larger inventory of self clinching nuts than most other fastener suppliers in the industry. We offer self clinching nuts with both inch and metric threads, in steel, stainless steel, and aluminum varieties.

Clinch Nut Installation Benefits

Self-clinching fasteners and nuts take less space and require fewer assembly operations than caged or anchor nuts. They also have greater reusability and more holding power than sheet metal screws. Some of the other advantages of self clinching nuts, include:
  • Provide strong threads
  • May be installed using any parallel acting squeezing force.
  • Provide high torque-out resistance.
  • Reverse side of metal sheet remains flush.
  • No retapping necessary.
  • Low installed costs.

Factors to Consider When Choosing Self Clinching Nuts

When selecting self clinching nuts for your application, several factors should be considered prior to clinch nut installation, these include: 
  • Ductility and thickness of the metal framework in which they will be installed.
  • The self clinching nuts function.
Additionally, self clinching fasteners can be installed during the initial manufacturing stages of your product or during final assembly.

Where to Use Clinch Nuts (PEM® Nuts)

Self clinching nuts are frequently used in applications where the sheet metal framework is too thin to tap. Once installed, these self clinching fasteners become permanent fixtures in the metal chassis. They are reusable as well, allowing for continued service over time.
To properly utilize a clinch nut the metal framework must be softer and more ductile than the final heat treated hardness of the metal used to produce the fastener—through a cold flow process, the metal wraps around the clinch profile of the nut, securing it in place.
In addition, punched holes must be sized correctly prior to installation to ensure that the self clinching nuts stay in place. The serrated sections of self clinching nuts prevent the fasteners from rotating when torque is applied.

Captive Fastener’s Self Clinching Nuts vs. PEM® Nuts*

Captive Fastener has been our choice for self clinching nuts and other self clinching fasteners for over 25 years. In that time, Captive’s products have repeatedly proven themselves to be as good, or better than the similar, but better known, PEM® nuts and fasteners.
For size, form, function, and durability, Captive Fastener’s self clinching nuts are all but identical to PEM® nuts. But when it comes to quality and value for the money, Captive is the far better choice. Replace your PEM® nuts with Captive’s self clinching nuts and we’re sure that you’ll agree.
