Special Thread Dies are any non-standard style or size die. Special pitch or thread form dies should be made to standard die dimensions where possible to keep costs down. They can be quoted for any quantity from one to several hundred. The larger the quantity, the less the individual cost. Pricing is based upon quantity ordered. Please inquire for pricing.
