Self-Clinching Nuts - Types JX-S, JX-CLS, JX-CLA, JX-SP

Material:

Brass or brass alloy: H63; H65; H68; H70; H90, etc.

Pressure rivet nut, also called rivet nut, or self-buckling nut, is a kind of nut applied to sheet metal or sheet metal, with a round shape, one end with embossed teeth and guide groove. The principle is to press into the pre-positioned holes of the sheet metal through the embossed teeth. Generally speaking, the diameter of the pre-positioned holes is slightly smaller than that of the embossed teeth of the rivet nut, so that the pressure makes the teeth of the rivet nut squeeze into the plate to make the pre-positioned holes of the periphery to produce plastic deformation, and the deformed material is squeezed into the guiding groove, thus producing the effect of locking.

1. The back of the plate remains completely flat;

2. Small and compact, suitable for all electronic or precision equipment;

3. High resistance to torque resistance;

4. Easy to equip, just simple pressure riveting;

5. Specification series, can meet a variety of design requirements.

Threaded nuts can take on many different forms to solve various application challenges, but the general concept is pretty simple. A nut is any single threaded part that can accept a male thread (a screw, bolt, or stud) and is used to join two components together via torque. The most common nut geometry is a hexagonal body with internal threads, the length of which is typically shorter than the outer diameter. The hex body can be leveraged to apply torque for tightening or loosening.

Application

The general form of a nut is so widely applicable that it’s challenging to narrow the scope without discussing more unique variations such as floating nuts, blind nuts, or flush nuts. Typical applications are as simple as fastening a stop sign to an aluminum post, or as critical as bolting two pipes together in a sewer system. The range of applications that use the general form of a threaded nut will typically result in different material decisions rather than design decisions, such as using high tensile strength bolts or lightweight, plastic nuts.

Alternative Solutions

Common reasons for using loose nuts and bolts include the low cost per piece and easy assembly/disassembly. Many applications require only ‘finger-tight’ fastening, meaning no additional tools are needed. If minimizing part count benefits the application, the nut can be eliminated by tapping threads directly into the steel post or sewer pipe. However, this results in two disadvantages. Tapping the thin metal of an aluminum post creates softer and fewer threads, increasing the risk of failure. Additionally, much of the cost savings gained by eliminating the nut is lost from the labor required to tap the metal panel.

Common Attachment Technologies

General threaded nuts are loose parts that mate with a male thread. However, a wide range of specific applications use nearly every kind of attachment technology to put threads on a metal panel or PCB. Self-clinching nuts are standard enough to be called clinch nuts.
