What is Thread rolling of stud bolts from STA rod stock?

Thread rolling of stud bolts from STA rod stock capability for titanium components

Fastener manufacturing capability for Thread rolling of stud bolts from STA rod stock, with cold forming, thread rolling, and 100% dimensional inspection.

Engineering Parameters & Capabilities

Thread rolling cold-forms threads by displacing material between two reciprocating or rotary dies, rather than cutting it away. Compressive residual stress at the thread root increases fatigue strength by 30–50% compared to cut threads, specifically for titanium components. Precision titanium components present unique challenges: balancing dimensional accuracy with cost per part. Process selection (mill vs. turn vs. EDM vs. laser) is optimized for each feature.

Parameter	Primary Method	Alternative Method
Method	Cold-forming: material displaced, not removed	Thread cutting / milling
Fatigue Strength	30–50% higher than cut threads	Standard (notch-sensitive)
Surface Finish	Ra 0.4–0.8 µm; work-hardened	Ra 1.6–3.2 µm
