Aanuraj Manufacturing Process

Built the hard way, one process at a time.

Every fastener passes through the same four disciplines before it leaves the plant.

01

Hot Forging

Grain-flow forged for strength under load, not machined from stock.

02

CNC Machining

Precision tolerances held across every batch, exotic alloy or standard grade.

03

Thread Rolling

Cold-rolled threads for fatigue resistance in high-vibration environments.

04

Testing & QA

In-house inspection plus NABL-approved and third-party lab coordination.
