Introduction: The Harsh Reality Behind OEM Rejections India is the world’s second-largest producer of fasteners , yet when it comes to OEM approvals  — whether in automotive, engineering, or industrial assemblies — most Indian manufacturers fail to cross the line. The result? European, Japanese, and American fastener suppliers continue to dominate global OEM supply chains, while Indian brands remain stuck in Tier-2 or Tier-3 vendor lists. The problem isn’t lack of capability

When you sit behind the wheel of a car, the last thing on your mind is a bolt. Yet, over 3,000 fasteners go into building a single passenger vehicle — each one holding together components that endure extreme heat, vibration, torque, and pressure. From engine mounts and brake systems to suspension assemblies and dashboard panels — fasteners are the silent force behind automotive safety, performance, and reliability.
