This used National Size 55 five-die progressive header (1985 production) is a compact, high-speed cold heading machine purpose-built for small-diameter fastener and precision part manufacturing. National Machinery's Size 55 platform is well known in the fastener industry for reliable, high-throughput production of small bolts, screws, rivets, and specialty cold-formed components.
With a maximum coil/blank diameter of 6.3mm, a maximum blank length of 25.4mm, and a die knockout length of 32mm, this header is optimized for smaller-gauge parts run at volume. It delivers a maximum production rate of 300 parts per minute (PPM) — well suited for high-volume small fastener production where cycle time and consistency matter most.
The 5 Die progressive forming process allows multi-stage shaping in a single continuous cycle, reducing secondary machining and improving dimensional repeatability across large production runs. This machine is available for inspection and sale from Jugal India Machinery's Delhi facility, with technical support available for relocation and installation.
