S-91280A660 M10 x 110 mm ISO 4014, DIN 931, ISO 898 Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior tensile strength with Class 8.8 rating (110,000 PSI) ensures reliable performance under high-stress conditions
• Enhanced corrosion resistance through zinc plating extends service life in demanding environments
• Optimized thread engagement with M10 coarse threading (1.5mm pitch) provides faster assembly and reduced cross-threading risk
• Precision external hex drive (17mm head width) enables secure tool grip and efficient installation with standard wrenches
• Controlled partial threading (26mm min thread length) offers superior clamping force distribution across 110mm length
• Consistent dimensional accuracy maintained through Class 6h thread fit for reliable mating with nuts and threaded holes
• Industry-standard compliance with ISO 4014/DIN 931 specifications guarantees interchangeability and quality assurance

Professional Applications & Engineering Value

This M10 hex head screw delivers exceptional engineering value through its Class 8.8 steel construction and zinc plated finish, specifically engineered to address common industrial challenges. The metric coarse threading (M10×1.5) combined with partial threading design prevents loosening under vibration while maintaining optimal shear strength. The external hex drive configuration ensures maximum torque transmission during assembly, making it ideal for structural applications in construction, machinery assembly, and heavy equipment manufacturing. With Rockwell C21 hardness and controlled thread fit Class 6h, this fastener provides predictable performance in high-load scenarios where dimensional stability and corrosion resistance are critical.

Specification Summary & Compliance

Manufactured to ISO 4014 and DIN 931 standards with Class 6h thread fit tolerance ensuring precise dimensional control. The partially threaded design features minimum 26mm thread length on the 110mm shank. 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 strength grade fasteners.
