Spring Washer DIN 127 ISO 7090 Washer Stainless Steel 304 A2 Purification
$30.99 – $131.99
Description
Spring washer DIN 127 (ISO 7090) made from Stainless Steel 304 (A2) offer reliable locking, corrosion resistance, and enhanced fastening security in purification, marine, food processing, and industrial applications. These washers provide elastic tension to prevent loosening due to vibration, thermal expansion, or mechanical stress, ensuring a secure and stable connection in dynamic environments. Ever Hardware provides custom made fasteners and customizable packaging.
Key Advantages
1. Anti-Loosening & Secure Fastening
• Spring-like tension creates continuous pressure on the fastener, preventing it from loosening due to vibration, shock, or movement.
• Ideal for dynamic applications where bolts and screws are subject to frequent loads.
2. Corrosion & Rust Resistance
• Made from 304 stainless steel (A2), providing excellent resistance to moisture, oxidation, and general corrosion.
• Suitable for outdoor, humid, and wet environments, including marine, purification, and chemical processing applications.
3. Enhanced Durability & Strength
• High mechanical strength ensures longevity, even under continuous stress.
• Withstands repeated load cycles without losing elasticity or breaking.
4. Suitable for Purification & Hygienic Applications
• Non-toxic and easy to clean, making it suitable for food, pharmaceutical, and water purification equipment.
• Smooth surface finish minimizes contamination risks in sensitive environments.
5. Resistance to Temperature & Environmental Changes
• Performs well in extreme temperatures and remains effective under thermal expansion and contraction.
• Suitable for outdoor structures, high-heat equipment, and fluctuating weather conditions.
6. Versatile & Multi-Industry Use
• Used in machinery, construction, automotive, aerospace, and industrial fastening applications.
• Compatible with bolted connections in structural, mechanical, and electrical assemblies.
Common Applications
• Purification & Water Treatment Plants – Corrosion-resistant, secure fastening for equipment.
