Special-shaped punching rods, including plum blossom, square, hexagonal, oval, and other shapes
Our company boasts professional CNC forming grinding machines that can automatically compensate and repair grinding wheels through computer control. These machines are capable of precisely producing various types of irregular-shaped punching rods, including square, hexagonal, plum-shaped, stepped, slotted, and irregularly contoured ones. They are compatible with mainstream multi-station cold heading machines on the market and are used for processing components such as irregular screws, special rivets, and non-standard automotive fasteners.
BenC Mould supports customization based on supplied drawings and samples, and can cooperate with new product development for rapid sample testing and prototyping. We optimize the structure and process of the punching rod, providing fastener enterprises with a stable and durable solution for cold heading punching rod matching.

Special-shaped punch pins for every recess and drive type: Torx punch (star), Pozi punch (Pozidriv), hex socket header punch, square punch, plum blossom and other profiles — all precision ground from tungsten carbide or HSS.
- Torx header punches — TX6–TX100, ground to gauge for full Go/No-Go recess compliance
- Pozi punches (Pozidriv) — PZ1–PZ4 for machine screws and wood screws
- Hex socket punches — hexagonal punches with sharp, burr-free corners
- Tamper Torx punches — with centre pin for security fasteners
- Custom header punches — any profile from your drawing or sample
Each carbide punch pin is vacuum heat treated and precision ground; optional TiN/TiAlN coating extends punch life on stainless steel and high-strength fasteners. Send us your recess spec — we’ll match the punch.
Special profiles can also be supplied on a brazed body — see the brazed carbide cold heading punch page for the construction and the blanks available from stock.
