S-91180A658 M10 x 90 mm ISO 8765, DIN 960 Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating that protects against rust and extends service life in demanding environments
• High tensile strength of 110,000 psi ensures reliable performance under heavy loads and vibration, reducing failure risks
• Class 8.8 strength grade provides excellent durability and load-bearing capacity for critical industrial applications
• Fine 1.25mm thread pitch delivers precise, secure fastening with reduced risk of loosening in machinery and equipment
• Partially threaded design allows for optimal clamping force distribution and easier alignment in assembly operations
• External hex head enables quick installation and removal with standard tools, improving maintenance efficiency
• Rockwell C21 hardness maintains structural integrity and resists wear during repeated use

Professional Applications & Engineering Value

This M10 hex head screw is engineered to address common industrial fastening challenges, particularly in applications requiring high tensile strength and corrosion resistance. The zinc plated steel construction provides a protective barrier against moisture and chemicals, making it ideal for outdoor equipment, automotive assemblies, and machinery exposed to harsh conditions. The fine thread with 1.25mm pitch ensures tight, vibration-resistant connections in precision components, while the partially threaded design prevents over-tightening and distributes stress evenly. With Class 8.8 mechanical properties and right-hand thread configuration, it offers reliable performance in structural frameworks, manufacturing fixtures, and heavy-duty industrial systems where safety and longevity are paramount.

Specification Summary & Compliance

This fastener meets ISO 8765 specifications (equivalent to DIN 960) with Class 6h thread fit for precise dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence. The metric thread system (M10 x 1.25) and 90mm length provide standardized compatibility, while the external hex drive and right-hand thread direction align with global industrial fastening standards for consistent quality and interoperability.
