Description:- F-KF-Thread-Finish e.g. F-KF2-M3-T
Broaching Nuts provide strong reusable threads in non-ductile materials, such as Printed Circuit Boards, Polycarbonates, Acrylics, Glass Epoxy, and Resin Laminates. (Please contact us for advice regarding any other materials you might wish to consider).
They are available in Steel with an Electro-Tin finish, or Stainless Steel.
Broaching Nuts can also be installed into Soft Aluminium, as an alternative to Clinch Studs & Nuts.
