S-90180A679 M24 x 80 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 150,000 psi tensile strength for reliable performance in high-stress environments
• Superior corrosion resistance through blue-dyed zinc plating that enhances durability in harsh industrial conditions
• Precise thread engagement with Class 6g fit and coarse 3mm pitch ensuring secure fastening and vibration resistance
• Optimized torque transmission via external hex drive and 36mm head width for efficient installation with standard tools
• Controlled thread distribution through partial threading design that concentrates strength where needed most
• Certified material integrity with Class 10.9 strength grade and Rockwell C32 hardness for consistent mechanical properties
• Reduced installation time with right-hand thread direction following industry-standard fastening conventions

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M24 hex head screws address critical challenges in structural assembly and machinery maintenance. The Class 10.9 steel construction provides exceptional resistance to dynamic loads and fatigue, making them ideal for construction equipment, industrial machinery frames, and transportation infrastructure where failure is not an option. The blue-dyed zinc-plated finish offers both corrosion protection and visual identification benefits in complex assemblies. With partial threading optimizing stress distribution and the metric coarse thread pattern ensuring rapid installation, these fasteners deliver reliable performance in time-sensitive maintenance operations and precision manufacturing environments requiring repeated disassembly and reassembly cycles.

Specification Summary & Compliance

Manufactured to ISO 4014 specifications (equivalent to DIN 931) with Class 6g thread tolerance ensuring precise fitment in metric applications. The 80mm length provides 54mm minimum thread engagement for secure connections. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, these screws meet international regulatory requirements for industrial use. The external hex drive configuration and right-hand thread direction follow global fastening conventions for compatibility with standard installation tools and procedures.
