Types of Self-Chinching Nuts and Studs

Apr 11,2022

Whether you need standard self-clinching nuts, standoffs or floating fasteners, there are a variety of options to fit your application.
Self-clinching nuts provide strong reusable threads in materials that are too thin to be conventionally tapped. They are installed by inserting them into properly sized holes and applying a parallel squeezing force to the head of the fastener. The parent material then cold flows into the undercut - securely locking in place with excellent pushout and torque resistance.
Thread Strength
Whether you’re looking to fasten components to a fabricated sheet-metal enclosure or just need strong, load-bearing threads in a thin metal panel, self-clinching nuts and studs are the solution. They provide high push-out and torque loads, and they require fewer assembly operations. Plus, they’re reusable! Each type has a unique code that identifies its style, material, shank size and thread code.
To install, place the fastener’s knurled end on a punched or drilled hole and squeeze. A hammer blow won’t work, as it will crush the head and deform the back-tapered section of the shank. For best results, a cold-flow process is recommended. For proper installation, it’s important to observe minimum edge distances as specified by the catalogue or product data sheet. Typical insertion forces range from 400 to 700 pounds.
Threaded Insert
The threaded insert in these fasteners helps to make the nut stronger, providing more resistance to spin-out. These nuts are designed to be installed using a pneumatic press, though they can also be manually clinched by an arbor press or other manual fastening tool.
Unlike rivet nuts, these can be installed in materials that are too thin to tap threads. They use a special clinching feature to securely affix themselves to the base material, making them strong and long-lasting.
This is a great alternative to weld nuts and other threaded fasteners, allowing you to save time and money while creating a secure connection in your panel. These are available in both studs and nuts, and we carry both standard and miniature sizes. Our miniature studs are especially useful in tight spaces such as handheld devices and small appliances. The nut and stud installs with a parallel squeezing force, and it ends up flush with one side of the sheet.
Floating
The float in these self-clinching nuts (CFAS & CFFC) allows the fastener to compensate for mating hole misalignment up to.030 inches (.8 mm). The floating nut insert is located in the head of the fastener and is held in place by a serrated ring that prevents the nut from rotating or loosing. These self-clinching floating nuts have good torque and push out characteristics and install flush on the underside of the panel.
These self-clinching floating nuts have a load-bearing female thread and allow up to 0.030" (0.8mm) float in all directions from the center. They are available in locking and non-locking versions and are made from electro zinc plated carbon steel or stainless steel.
These nuts, standoffs and studs are installed by placing them in properly pre-cut holes in sheets and applying enough force for the metal to cold flow into an undercut. This makes the clinch nut an integral part of the sheet. These fasteners are ideal for thin panels where it is impractical or impossible to install tapped holes.
Miniature
A miniature version of the standard self-clinching nut, this type uses a smaller thread cavity for smaller hardware. They are used where space is a premium or installation is close to the edge of the panel. The nut moves to correct misalignment during installation.
The nut fits into a minimal space and provides strong, reusable female threads in panels that are too thin to be conventionally tapped or where access is limited on both sides of the sheet. They are available in locking and non-locking versions. The locking series (types FE, FEO and UL) have an elliptically deformed body with dry film lubricant that gives them prevailing torque locking characteristics to limit loosening under vibration.
These fasteners are made of 300-series stainless steel for use in ductile metal panels that are hard enough to clinch the head without a separate forming operation. The nut body is coated with black dry film lubricant finish over cadmium plating. They are not RoHS compliant because the cadmium plating contains over 0.1% lead and the nut may contain over 0.1% lead phosphite.
