S-91310A154 M16 x 100 mm ISO 4017, DIN 933 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with Class 10.9 strength grade, supporting up to 150,000 psi tensile strength for demanding structural applications
• Superior wear resistance thanks to Rockwell C32 hardness, ensuring long-term performance in high-vibration environments
• Optimized installation efficiency with external hex drive and 24mm head width for secure tool engagement and torque transmission
• Reliable thread engagement through Class 6g thread fit and M16x2mm coarse pitch design, preventing cross-threading in industrial assemblies
• Full-length threading provides consistent clamping force distribution along the entire 100mm length
• Comprehensive regulatory compliance with RoHS 3 and REACH standards, ensuring environmental responsibility in global supply chains
• Standardized dimensions per ISO 4017/DIN 933 specifications, guaranteeing interchangeability and replacement compatibility

Professional Applications & Engineering Value

These Class 10.9 hex head screws deliver critical performance in heavy-duty industrial applications where failure is not an option. The high-tensile steel construction combined with Rockwell C32 hardness addresses common challenges of joint relaxation under dynamic loads and environmental corrosion. The M16x2mm coarse thread pitch ensures rapid installation in structural steel, machinery frames, and equipment bases while maintaining Class 6g thread fit precision. The fully threaded design provides uniform stress distribution across the entire 100mm length, eliminating weak points in critical connections. External hex drive compatibility with standard tools simplifies maintenance in confined spaces, making these metric bolts ideal for manufacturing, construction, and automotive applications requiring superior durability.

Specification Summary & Compliance

Manufactured to ISO 4017/DIN 933 standards with Class 6g thread tolerance for precision fit. The M16x2mm coarse pitch threading and 100mm length maintain dimensional accuracy per metric specifications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Class 10.9 strength rating corresponds to 150,000 psi minimum tensile strength with Rockwell C32 hardness verification.
