M3 SQ Med SPR Washer Plain

Description

SQ Med SPR Washer Plain (Square Medium Section Spring Washer) is a specialized split-ring locking fastener designed to prevent bolts and screws from loosening due to vibration or movement. These washers typically conform to DIN 7980 or DIN 127 standards and feature a "square" cross-section that provides a balanced distribution of load Technical Specifications According to manufacturers like Fowkes Bros, these washers are available in various sizes and materials tailored for specific environments: Standards: Most frequently conform to DIN 7980 for square medium spring washers. Some variants may also meet DIN 127 standards. Materials: Stainless Steel A2 (304): Offers durability and standard corrosion resistance for freshwater and general industrial use. Stainless Steel A4 (316): Provides superior resistance for marine, chemical, and harsh outdoor environments. Galvanized / Zinc Plated: Hardened metal with protective coatings for automotive and construction applications to prevent rust. Black Finish: Chemically treated for additional corrosion resistance and professional aesthetic. Primary Applications Mechanical Assemblies: Used to maintain preload and clamping force in joints subjected to vibration, preventing fastener back-off. Automotive and Industrial: Ideal for securing components in engines or heavy machinery where thermal expansion and contraction occur. Marine and Chemical: High-grade stainless steel versions (A4 316) are used where exposure to saltwater or chemicals is constant. Sanitary Conditions: Stainless steel variants are suitable for environments requiring hygienic standards, such as medical or food processing equipment
