S-91287A481 M20 x 200 mm ISO 4014, DIN 931 18-8 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional load-bearing capacity thanks to 100,000 psi tensile strength for heavy-duty applications
• Reliable coarse threading (M20 x 2.5 mm pitch) ensures faster assembly and reduced cross-threading risks
• Precise Class 6g thread fit guarantees consistent engagement and vibration resistance
• Optimized partial threading provides unthreaded shank for enhanced shear strength and alignment
• External hex drive design allows for high-torque installation with standard tools
• Full regulatory compliance with RoHS 3 and REACH for safe use across regulated industries

Professional Applications & Engineering Value

This M20 hex head screw delivers critical performance where structural integrity matters most. Manufactured from 18-8 stainless steel, it resists oxidation and chemical exposure in demanding settings like machinery assembly, structural steelwork, and outdoor infrastructure. The coarse metric thread (2.5 mm pitch) maintains holding power even in vibration-prone applications, while the partially threaded design concentrates stress away from the thread roots. With ISO 4014 DIN 931 certification, this 200 mm fastener ensures dimensional consistency for replacement and OEM specifications across global projects.

Specification Summary & Compliance

This hex head screw meets ISO 4014 DIN 931 specifications with Class 6g thread fit tolerance. The M20 x 2.5 mm coarse thread and 46 mm minimum thread length adhere to standardized metric dimensions. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial use.
