Conical Knurled Spring Washer-HEBEI A&Z INTERNATIONAL CO., LTD.|Anti-Vibration Fasteners&Corrosion Resistance

Fasteners are the unsung heroes of engineering, ensuring the integrity of structures, machinery, and systems across industries. Among these, the Conical Knurled Spring Washer stands out as a revolutionary solution for preventing loose fasteners. Designed to combine the strength of conical springs with the gripping power of knurled surfaces, this product addresses common challenges in vibration, corrosion, and mechanical stress. In this article, we explore its advanced features, technical specifications, and real-world applications, all while highlighting the expertise of its manufacturer, HEBEI A&Z INTERNATIONAL CO., LTD..

Product Overview

The Conical Knurled Spring Washer is a high-performance fastening component engineered to prevent loosening in dynamic environments. Its unique design integrates a conical spring with a 360° knurled contact face, offering superior resistance to vibration and torque. This washer is particularly effective in applications where traditional washers fail due to mechanical stress or environmental factors.

Key Features and Advantages

The Conical Knurled Spring Washer is designed to deliver unmatched performance. Below are its core features and advantages:

• Advanced Material Composition: Manufactured from 304/316 stainless steel, the washer offers exceptional corrosion resistance, with a salt spray test rating of over 500 hours (ASTM B117). This makes it ideal for harsh environments.
• Superior Anti-Vibration Design: The conical spring geometry combined with 360° knurling provides 200% higher anti-vibration force compared to standard serrated washers, as validated by NIST standards.
• Zero Galling Mechanism: The radial knurls bite into the substrate without requiring pre-drilling, eliminating galling on soft metals and ensuring a secure lock.
• Wide Compatibility: Designed to fit M3 to M16 fasteners (DIN 6796/ISO 10683), it is fully compatible with ISO metric bolts, making it versatile for global applications.
• Extreme Temperature Resistance: The 316SS variant operates reliably between -55°C and +300°C, suitable for aerospace and automotive industries.
• Global Certifications: Compliant with RoHS 3, REACH, and DIN 6796 Type A standards, ensuring adherence to international quality and safety regulations.
