S-91310A654 M10 x 80 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 PSI ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in critical applications.
• Class 10.9 strength grade provides superior load-bearing capacity and fatigue resistance, ideal for heavy-duty machinery and structural assemblies.
• Partially threaded design with 26mm minimum thread length allows for precise clamping force control and secure engagement without unnecessary thread contact.
• Rockwell C32 hardness enhances wear resistance and durability, extending service life in abrasive or high-vibration environments.
• Coarse metric thread (M10 x 1.5mm) facilitates quick installation and reduces cross-threading risks, improving assembly efficiency.
• External hex drive and hex head enable easy torque application with standard tools, ensuring consistent tightening in confined spaces.
• Full compliance with ISO 4014/DIN 931 standards guarantees dimensional accuracy and interchangeability, streamlining procurement and inventory management.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, this M10 hex head screw combines Class 10.9 steel with a partially threaded configuration to address common engineering challenges like vibration loosening and misalignment. The coarse metric thread (M10 x 1.5mm) ensures rapid assembly in structural steelwork, automotive frames, and heavy machinery, where high tensile strength (150,000 PSI) and Rockwell C32 hardness prevent deformation under dynamic loads. Its external hex drive allows for secure torque transmission, minimizing slippage during installation. Ideal for applications requiring DIN 931 compliance, this fastener delivers consistent performance in construction, manufacturing, and equipment maintenance, reducing downtime and replacement costs.
