About This Section

Chipless Threading with Superior Strength

Thread rolling is a cold-forming process that displaces material rather than cutting it — producing threads with continuous, unbroken grain flow, work-hardened surfaces, and significantly higher fatigue strength than cut or ground threads. Pivot Fabrique's Thread Rolling Section operates a dedicated fleet of flat die and cylindrical die rolling machines covering M3 to M20, purpose-built for high-volume automotive and industrial production under ISO/TS 16949:2009 quality control.

Flat Die Rolling

High-speed reciprocating flat die machines — ideal for short fasteners, studs, and pins with consistent production rates.

Cylindrical Die Rolling

Two-roll cylindrical die machines for longer shafts and threaded components — precision pitch control over extended lengths.

M3 to M20 Range

Complete metric coverage from fine fasteners to heavy-duty bolts — with imperial and special-profile threads available on request.

Superior Thread Quality

Up to 30% higher fatigue strength versus cut threads — burnished surface finish, no chips, no machining marks.

Threading Workflow

From Blank to Rolled Thread

Every component processed in our thread rolling section follows a structured, quality-verified workflow — ensuring correct pitch, thread profile integrity, and surface finish from first-off through batch production.

01
📋
Blank Verification
Turned blank checked for pitch diameter, surface condition, and length — correct blank diameter is critical to rolled thread accuracy.
02
🔧
Die Selection & Setup
Correct flat or cylindrical die set mounted per thread specification — pitch, profile, and class. Machine timed and pressure set.
03
🔄
Cold-Form Rolling
Blank fed between dies under pressure — material displaces into thread profile without removing chips, creating burnished surfaces.
04
🔬
Thread Inspection
First-off and in-process checks using ring & plug gauges, thread micrometers — verifying pitch diameter, profile, and tolerance class.
05
Batch Clearance
Cleared batch tagged with inspection report and routed to next operation — heat treatment, plating, or final despatch as per route card.
Why Our Thread Rolling Section

The Advantage of Cold-Form Threads

With 8 flat die rolling machines and 4 cylindrical die rolling machines covering M3 to M20 — our thread rolling section produces chipless, work-hardened threads with up to 30% higher fatigue strength than cut threads, entirely in-house at production scale.

💪

Higher Fatigue Strength

Continuous grain flow and work-hardened root surface deliver up to 30% greater fatigue life than cut or ground threads.

Burnished Surface Finish

Cold-forming produces a smooth, polished thread surface — typically Ra 0.4–0.8μm — eliminating machining marks and stress risers.

♻️

Chipless & Material Efficient

Material is displaced, not cut — zero swarf, lower raw material consumption, and a cleaner shop floor.

High Production Speed

Thread rolling cycle times are a fraction of single-point cutting — purpose-built for automotive volume schedules.

🎯

Consistent Class 6g Threads

Hardened dies produce thousands of identical threads — repeatable pitch, profile, and tolerance batch after batch.

📦

Integrated with Full Process Chain

Thread rolling output feeds directly into heat treatment, plating, and quality — complete single-vendor continuity.
