Manufactured in
four controlled stages.
From wire rod to finished, coated, inspected part — four stages, one Ludhiana facility, full lot traceability throughout.
01
Raw material
Carbon steel wire rod — C45 or 10B21 — supplied with EN 10204 3.1 MTC. Each heat is certified for chemistry and mechanical properties before production begins.
02
Cold heading
Wire is fed into a multi-station header. The hex body and integral flange are formed in the same stroke — no material removed, no weld lines, net-shape part.
03
Thread rolling
Internal threads rolled, not cut. Rolling displaces material rather than removing it, keeping grain flow continuous through the thread root for improved fatigue resistance. Tolerance: 6H per DIN 13.
04
Heat treatment, coating & inspection
Quench-and-temper to Class 10 (800–1040 MPa). Zinc electroplate, hot-dip galvanising, or Geomet 500 applied to order. De-embrittlement bake standard on electroplated parts. Every nut sorted optically then checked with calibrated Go / No-go gauges. EN 10204 3.1 MTC issued per lot. Lot retains held for ten years.

From a Class-8 tractor at 800 ft-lb of torque, to the trailer that follows it across two borders, to the agricultural axle that turns once a season — same family of parts, same DIN, same lot.
