Tungsten Carbide Fastener Die Blanks for Cold Heading Dies
Our R&D engineers combine coarse and fine-grain tungsten carbide powders with a high-cobalt formula to produce cold heading dies with improved impact and wear resistance.
It better prevents cracking of cold heading dies, withstands harsher working conditions and improves cold-heading efficiency.
The primary failure mode of fastener dies is cracking, so we have developed impact-resistant carbide for fastener dies.
Advantages

Frequently Asked Questions
Which die blank shapes do you supply?
NIB blanks, punch blanks and custom preforms for bolt, nut and screw making machines.
Are blanks supplied sintered or finished?
Sintered blanks for your own finishing, or fully machined die assemblies — both are available.
Which grades suit cold heading?
What is the MOQ and can I order samples first?
There is no fixed MOQ for standard items. Sample orders are welcome so you can verify quality before volume production; shipping is freight collect.
What is the typical lead time?
Standard items are usually shipped in 7–15 days. Custom blanks depend on complexity and are confirmed with the quotation.
