Frequently Asked Questions
Q1: What materials do your thread rolling dies support?
A: Sourced dies support low-carbon steel, stainless steel (300/400 series), heat-treated alloys (grades 8.8, 10.9, 12.9+), titanium, A-286, 8740-0447, Wasphalt, and Inconel.
Q2: What is the difference between M2 and M42/SPECTRA grades?
A: M2 suits standard-hardness materials (≤28 HRC) and non-heat-treated screws. M42/SPECTRA with nitriding treatment is designed for hardness above 36 HRC and aerospace-grade materials requiring higher wear resistance.
Q3: Can you source custom thread profiles?
A: Yes. Custom profiles including special threads, grooves, recesses, and knurls can be manufactured to specification.
Q4: What thread standards are supported?
A: Metric, UNC, UNF, and custom thread standards are supported, with standard sizes from M1.0 to M24 available.
Q5: How long do thread rolling dies typically last?
A: Tool life depends on the material being rolled and operating conditions.
Q6: Do you provide technical support for die selection?
A: Yes. Our sourcing team assists with material grade selection and die specification based on your application data.
