S-90854A159 M10 x 95 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength with Class 10.9 rating (150,000 PSI) ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Superior corrosion resistance from zinc yellow-chromate plating extends service life in harsh environments, minimizing maintenance and replacement costs.
• Precision thread fit (Class 6h) provides consistent engagement and vibration resistance, enhancing assembly integrity and reducing loosening over time.
• High hardness (Rockwell C32) offers excellent wear resistance, maintaining thread integrity and dimensional stability through repeated use.
• Partially threaded design allows for secure clamping in specific joint types, improving load distribution and preventing over-tightening.
• External hex drive with standard head dimensions enables easy installation using common tools, speeding up assembly and reducing labor time.
• Compliance with ISO 4014/DIN 931 standards guarantees interchangeability and quality assurance, ensuring compatibility with global engineering specifications.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this M10 hex head screw addresses critical challenges in machinery, structural frameworks, and automotive assemblies. The Class 10.9 steel construction provides a robust solution for high-vibration environments, where tensile strength and fatigue resistance are paramount. The coarse thread (1.5 mm pitch) ensures quick assembly and reliable holding power in materials like cast iron or soft metals, reducing the risk of cross-threading. With zinc yellow-chromate plating, it offers enhanced protection against corrosion in outdoor or humid conditions, extending the lifespan of critical connections. The partially threaded shank design allows precise load-bearing on the unthreaded portion, ideal for bolted joints requiring shear strength. This metric fastener is a trusted choice for engineers seeking durability, compliance, and performance in industrial fastening systems.
