Threaded Inserts - Aluminium
See also Nutsert Dimensions . The Aluminium Threaded Insert (often call Nutsert or Rivnut) is a female thread (nut) used in sheetmetal or areas with no access behind. It is like a blind rivet and has at one end either a flat flange or a small countersunk/rimless flange, and a portion of plain barrel. It is the plain barrel part that can be crushed up around the sheet metal, thereby forming a nut like fitting fixed through the parent sheet metal.
Aluminium Threaded Insert (Nutsert/Rivnut) Sizing
Anzor carries standard metric thread Threaded Inserts in Aluminium like M4, then followed by the length. Length is denoted in brackets as the thickness range that the insert will pull up on. This has to match the thickness of the sheet-metal you are putting the insert into. This thickness range is often called the ‘draw’ or ‘Grip’ thickness.
Aluminium Threaded Insert (Nutsert/Rivnut) applications
Mainly used in sheet metal fabricated products, such as air conditioning ducting, light fittings, electrical distribution boxes. The uses are varied but usually sheet metal.
Aluminium Threaded Insert (Nutsert/Rivnut) advantages
The advantages of using threaded inserts are that they are; easy to use, quick, permanent, and actually increases the strength of the fastening in the sheet metal. However special tools and drilling required tofit the Threaded Insert and care and attention should be taken to ensure the correct use of the tool. Anzor can supply you with an instruction manual. The Insert may rotate after being done up, especially if the fastening seizes in the thread, the use of a lubricant will help to avoid this.
Threaded Inserts have a wide spread use throughout Sheet metal, Electrical and General engineering industries. They are relatively easy to use, but special tools and some training required.
Threaded Insert (Nutsert) Tooling
The ‘Threaded Insert Tool’ that is used can be hand operated or in production cases it is normally air operated.
