Self Clinching Blind Fasteners are used in applications requiring closed end threads.
Also known as clinching blind press nuts, they provide an excellent design solution for assemblies where there is a desire to protect the contents from foreign matter.
The blind press nuts can be installed into panels as thin 1.0mm. The configuration of the blind press nuts also limit the mating screw’s penetration into the assembly which can prevent any interference within the design.
This feature prevents any contact with the electronic circuitry in the design.
In contrast to the open version, the closed end self clinching nuts offer the advantage of a longer threaded part. The closed shank end seals the thread against external influences such as dirt, oil, moisture and protects against atmospheric corrosion.
In addition, their use is generally more cost-effective than comparable fasteners with similar sealing properties, which, however, require complicated seals and special assembly procedures.
- Provide barrier against foreign matter
- Limits screw penetration thereby protecting internal components
- A sealing effect is achieved
These nuts provide a permanent blind thread in thin metal sheets.
The blind press nuts, along with providing the protection of shielding foreign matter from the design, and the mating screws penetration, they also eliminate the possibility of loose hardware.
The blind fastener encapsulates your threads, typically to prevent any foreign material from entering inside. Protrudes on one side of the sheet metal.

They can be easily installed into correct sized holes with a standard press applying squeezing force between parallel surfaces.
The proper installation of each series of blind press nuts requires that the self clinching fastener is harder than the panel into which it will be installed. To be installed properly, they must be inserted in the proper mounting hole in the panel.
The minimum sheet thickness and proper hole size for each individual fastener is listed in our product datasheet.
The proper method to install the fasteners requires that a slow squeezing force be applied, which allows the parent metal to flow around the clinch profile of the fastener. This procedure captivates the fastener in the assembly and they become an integral part of the design.
The blind press nuts allow for assembly and later servicing of the assembly if required, with no need to access both sides of the panel. The blind press nuts, along with providing the protection of shielding foreign matter from the design, and the mating screws penetration, they also eliminate the possibility of loose hardware.
