A secondary machine process is omit, and that production efficiency of the fastener is improved.
Aft that cold-heading blank is pre-headed and for, the excess flash of the head is sheared and removed by a trimming die, and the hexagonal, square and other multilateral shapes are directly for, so that the secondary machining process is omitted, and the production efficiency of the fastener is improved.
- High speed steel imported from Japan
- Regenerative cooling technology after vacuum heat treatment
- Support the customization of non-standard parts

Hex heads, square heads and special profiles are often trimmed after forming to remove flash and achieve precise edges. Our screw trimming dies are matched to your forming die set for a clean, flash-free, repeatable finish.
Each trimming die is made from high-grade tool steel or tungsten carbide, vacuum heat treated and precision ground — so the trimmed hexagon is burr-free without fracture marks, pass after pass.
Pair our screw trimming dies with your bolt forming die set — send us your header model and part print.
