FAQ

Frequently Asked Questions About Flat Thread Rolling Die

Q1 What materials do you use for your flat thread rolling dies?
We use premium tool steels like M2 (HSS) and M42. Combined with our proprietary vacuum heat treatment, our flat thread rolling die balances extreme surface hardness with superb core toughness.
Q2 What is your minimum order quantity (MOQ) for a custom flat thread rolling die?
Our standard MOQ starts at just 4 SETS, making it highly cost-effective for testing new fastener prototypes or handling small-batch customized production.
Q3 Can I customize the flat thread rolling die with our own thread profile designs or logos?
Yes, absolutely. We provide comprehensive OEM/ODM services. You can send us your work-piece drawings, machinery specifications, or logo requirements, and our engineers will design the exact tool profile.
Q4 How do you solve the issue of tooth chipping when rolling Grade 12.9 bolts?
Chipping usually occurs due to excessive brittleness or improper entry-zone alignment. We solve this by implementing customized stress-relieving tempering on our flat thread rolling die and modifying the tooth entry relief to match your blank's precise hardness.
Q5 What is the standard lead time for wholesale flat thread rolling die orders?
For standard specifications, delivery takes 25 days. For highly customized ODM or specialized flat thread rolling die orders, the delivery cycle is within 35 days, depending on the material and coating requirements.
