S-94036A625 M10 x 25 mm ISO 898-1, DIN 6921 Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc yellow-chromate plating, extending service life in harsh industrial environments
• High tensile strength of 110,000 psi and Class 8.8 grade for reliable performance in demanding applications
• Integrated flange design eliminates the need for separate washers, simplifying assembly and reducing component count
• Precise Class 6g thread fit ensures smooth installation and secure fastening in metric coarse threaded applications
• External hex drive with standard 15mm head provides excellent torque transmission and familiar tool compatibility
• Rockwell C22 hardness rating maintains structural integrity under heavy loads and vibration
• Partially threaded shank design offers optimal grip range while preventing thread damage in clearance holes

Professional Applications & Engineering Value

This M10 hex flange screw delivers exceptional engineering value through its zinc yellow-chromate plated steel construction, specifically engineered to combat corrosion in industrial settings. The Class 8.8 strength rating and 110,000 psi tensile strength make it ideal for heavy-duty applications where joint integrity is critical. The integrated flange design distributes clamping force over a wider surface area (22.3mm diameter), preventing surface damage and maintaining seal integrity in automotive, machinery, and structural assemblies. The coarse M10x1.5mm thread provides rapid installation and superior resistance to vibration loosening, while the partial threading allows for precise grip length control in layered materials.

Specification Summary & Compliance

This 25mm length hex flange screw features Class 6g thread tolerance with 20mm minimum thread length and M10x1.5mm coarse pitch threading. Manufactured to ISO 898-1 specifications and DIN 6921 standards, ensuring dimensional accuracy and performance consistency. Compliant with REACH regulations (EC 1907/2006) for environmental safety and contains no SVHC above threshold limits as of June 2023 declaration.
