Product Overview

Accelerate your fastener manufacturing and cold-forging production cycles with our high-impact Tungsten Carbide Cold Heading Die Inserts. Explicitly engineered to withstand severe, high-frequency repetitive axial impacts and intense radial expansion stresses, these premium cemented carbide pellets (nibs) serve as the heavy-duty wear cores inside multi-station cold heading steel mold housings.

Available as precision-sintered or semi-finished blanks equipped with centered pre-formed pilot holes, these carbide inserts allow for straightforward wire-EDM customization, final sizing, and diamond polishing. They provide unbeatable dimensional preservation for high-volume manufacturing of high-tensile bolts, nuts, rivets, and screws.

Technical Specifications & Standard Ranges

We supply a comprehensive dimension matrix to fit global headers, piece-formers, and progressive nut formers:

Target Applications & Machinery

Our rugged carbide cold heading cores are highly recommended for tooling setups in:
