Professional Applications & Engineering Value
This zinc-plated steel pan head screw delivers exceptional engineering value for industrial assembly applications where corrosion resistance and mechanical reliability are critical. The M8 coarse thread (1.25mm pitch) with Class 6h fit ensures rapid installation and secure fastening in metal-to-metal applications, while the fully threaded design provides maximum thread engagement throughout the 20mm length. The wide pan head profile distributes clamping force effectively, preventing surface damage and maintaining joint integrity under vibration. Particularly valuable in electrical enclosures, machinery assembly, and automotive components, this DIN 921 compliant fastener solves common challenges of thread stripping, corrosion-induced failure, and installation inefficiency in high-volume production environments.
Specification Summary & Compliance
This metric pan head slotted screw features M8 x 1.25mm coarse threads with Class 6h thread fit per ISO metric standards, ensuring precise dimensional accuracy. Manufacturing follows DIN 921 specifications for pan head screw geometry and dimensional requirements. The product demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for regulated industrial applications across international markets.
