S-91287A201 M12 x 90 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 for long-lasting performance in harsh industrial environments
• High tensile strength of 100,000 psi ensures reliable fastening under heavy loads and vibration
• Precision Class 6g thread fit provides consistent engagement and reduces the risk of cross-threading during installation
• External hex drive design allows for high-torque application with standard tools, speeding up assembly processes
• Partially threaded shank offers optimal grip length control and prevents over-tightening in critical joints
• Comprehensive regulatory compliance including RoHS 3 and REACH ensures environmental and safety standards are met
• Coarse thread pitch (1.75mm) enables quick installation and superior performance in softer materials

Professional Applications & Engineering Value

This M12 hex head screw delivers exceptional engineering value through its 18-8 stainless steel composition and metric coarse threading. The combination of 100,000 psi tensile strength and corrosion-resistant properties makes it ideal for demanding applications in machinery assembly, structural frameworks, and outdoor equipment where exposure to moisture and chemicals is common. The partially threaded design provides precise clamping force distribution while the external hex drive ensures efficient installation with common industrial tools. Meeting ISO 4014/DIN 931 specifications, this fastener solves critical challenges in maintenance accessibility, vibration resistance, and long-term reliability across manufacturing, construction, and heavy equipment sectors.
