Overview
DIN 7331 is a product specification standard for snap fasteners used in industrial, automotive, textile, and commercial assembly applications. It defines dimensional characteristics, fastening configurations, and performance requirements to support reliable engagement and fastening consistency. The standard is commonly referenced together with material, coating, and inspection standards depending on the application requirements. DIN 7331 snap fasteners are commonly available in steel, stainless steel, brass, and corrosion-resistant finishes. When sourcing products to DIN 7331, additional specifications may include fastener size, material requirements, finish or coating, retention requirements, and certification requirements.
