About Insert Nut (for Plastic Parts)

Threaded inserts put a metal thread into plastic so the part can be assembled and disassembled repeatedly. They install by heat, ultrasonic, press-in or moulding-in; the knurl and grooves resist pull-out and rotation.

Also known as Insert Nut · Threaded Insert · Heat Set Insert

Brass: Conducts heat well — the standard for heat-set and ultrasonic inserts.
Aluminium: Light and inexpensive for low loads.
304 stainless: Corrosion resistance or higher strength.

How to choose

Choose the installation method first; knurl profiles are not interchangeable.
Follow the maker's recommended pilot hole — too big loses pull-out, too small splits the boss.
Heat-set inserts suit 3D printed parts better than press-in types.
