From raw material to finished fastener, precision is built into every process.
We begin with sourcing high-quality raw materials such as alloy steel, carbon steel, and stainless steel round bars. Each batch undergoes visual inspection to detect surface defects and verify dimensional accuracy.
Approved raw materials are issued to the production department where they are cut into required lengths as per specifications. Each cut piece is checked for dimensional accuracy before moving to the next stage.
During the threading process, each fastener is manufactured with precision to ensure proper fit and strength. We use GO and NO-GO gauges to verify thread accuracy and maintain strict dimensional tolerances.
After initial inspection, components are transferred to the forging unit where bolts and nuts are shaped using controlled processes. Post-forging, dimensional inspections are conducted to ensure conformity with specifications.
We carry out in-house heat treatment using controlled cycles including heating, soaking, quenching, and tempering. This process enhances the mechanical properties of the fasteners such as hardness, strength, and durability.
We perform comprehensive in-house testing to ensure product quality:
Statistical quality control methods are applied to maintain consistency and reliability.
Finished products undergo cleaning and oiling to prevent rust. Based on client requirements, we provide various surface coatings:
Coating thickness and specifications are maintained as per client standards.
Before dispatch, all products undergo final inspection to ensure compliance with specifications. If required, third-party inspections are arranged.
We provide complete documentation including:
Products are then securely packed and dispatched within committed timelines.
