Industrial Spring Washers Manufacturer in India | Heavy Duty Washers - Durga Spring

Introduction —Industrial Spring Washers Manufacturer in India

Reliable fastening is critical for the safety and longevity of heavy machinery and infrastructure. Durga Spring is a premier industrial spring washers manufacturer in India, dedicated to producing high-performance locking components that prevent loosening due to vibration or thermal expansion. We specialize in manufacturing high-tensile spring steel washers that meet rigorous international standards, including DIN 127 and DIN 7980. Our infrastructure supports mass production for diverse sectors such as railways, automotive, power generation, and construction, ensuring that every washer delivers consistent load distribution and superior holding power in demanding environments.


Manufacturing Standards & Production Excellence

As a leading manufacturer, we strictly adhere to quality control protocols to ensure our spring washers can withstand high static and dynamic loads. Our manufacturing process includes:

  1. Precision Coiling & Stamping: We utilize automated machinery to ensure precise dimensions and uniform helix angles for optimal locking action.
  2. Controlled Heat Treatment: All washers undergo specialized hardening and tempering to achieve the perfect balance of elasticity and toughness, preventing brittleness.
  3. Surface Protection: To combat industrial environments, we offer various finishes including zinc plating, mechanical galvanizing, and black oxide to ensure long-term corrosion resistance.
This rigorous approach guarantees that our products perform reliably as critical safety components.

Maintenance & Safety Tips — Fastener Integrity

Checklist Durga Spring

Installation & Usage

  • Always place the spring washer between the nut and the flat washer (or mating surface) to maximize the locking effect against the nut.
  • Ensure the correct torque is applied; over-tightening can flatten the washer permanently, causing it to lose its spring action.
  • Select the correct material grade (e.g., Stainless Steel) if the application is exposed to moisture or chemicals to prevent rust failure.

Inspection Protocols

  • During maintenance, visually inspect washers for hydrogen embrittlement cracks, which can occur in high-tensile plated parts.
  • Do not reuse spring washers after disassembly in critical applications, as they lose their elastic memory and locking capability.
  • Verify that the washer ends (split) have not opened up significantly, which indicates material fatigue or improper heat treatment.

FAQs about Industrial Spring Washers
