S-91280A644 M10 x 60 mm ISO 4014, DIN 931, ISO 898 Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance through zinc plating, extending service life in harsh industrial environments
• Superior load-bearing capacity with Class 8.8 tensile strength (110,000 psi) for reliable performance under high stress
• Optimized thread engagement with M10 coarse threading (1.5 mm pitch) enabling faster assembly and reduced cross-threading risks
• Precision torque transmission via external hex drive and 17mm head width for secure fastening with standard tools
• Controlled thread distribution through partial threading design, providing unthreaded shank for enhanced shear strength
• Consistent dimensional accuracy with Class 6h thread fit ensuring reliable mating with nuts and threaded holes
• Regulatory compliance assurance meeting international ISO 4014/DIN 931 standards and environmental directives

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M10 hex head screws deliver critical performance where vibration resistance and structural integrity are paramount. The Class 8.8 steel construction provides optimal strength-to-weight ratio, while the zinc plating creates a sacrificial barrier against oxidation in manufacturing facilities, outdoor equipment, and automotive assemblies. The coarse thread metric design with 1.5 mm pitch ensures rapid installation in steel frameworks, machinery bases, and structural connections where partial threading prevents loosening under dynamic loads. With Rockwell C21 hardness, these external hex drive fasteners maintain dimensional stability under repeated torque applications, making them ideal for maintenance-critical environments requiring dependable industrial fasteners.

Specification Summary & Compliance

Manufactured to ISO 4014/DIN 931 specifications with Class 6h thread fit tolerance ensuring precise metric threading compatibility. The 60 mm length with 26 mm minimum thread length provides standardized engagement depth. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, alongside mechanical properties certified to ISO 898 standards for Class 8.8 tensile strength verification.
