S-98093A619 M10 x 25 mm ASME B18.2.3.9M, SAE J1199 High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional Corrosion Resistance: Black-phosphate steel coating provides superior protection against rust and environmental degradation, extending service life in harsh conditions.
• High Tensile Strength for Demanding Applications: Class 10.9 grade and 150,000 psi tensile strength ensure reliable performance under heavy loads and high-stress environments.
• Optimized for Secure Fastening: The integrated flange distributes load evenly, reducing the risk of surface damage and providing a larger bearing area for enhanced joint stability.
• Precision Threading for Reliable Fit: Class 6g thread fit and M10x1.5 coarse thread pitch enable easy assembly and a secure, vibration-resistant connection.
• Robust Material Hardness: Rockwell C32 hardness offers excellent wear resistance, maintaining thread integrity and fastener shape through repeated use.
• Efficient Installation and Removal: External hex drive and standard hex head design allow for quick, tool-friendly installation with common wrenches.
• Full Thread Engagement: Fully threaded design maximizes grip length and pull-out strength, ideal for applications requiring deep penetration and uniform clamping force.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this M10 hex head screw addresses critical challenges in construction, machinery assembly, and automotive sectors. The black-phosphate steel construction combats corrosion in outdoor or chemically aggressive settings, while the Class 10.9 strength grade ensures structural integrity under dynamic and static loads. The fully threaded and flanged design eliminates the need for separate washers, streamlining assembly and enhancing load distribution on softer materials. With metric coarse threading (1.5mm pitch), it resists loosening from vibrations, making it a dependable choice for bolted connections in frames, brackets, and equipment where reliability and compliance with international standards are paramount.

Specification Summary & Compliance

This fastener adheres to precise dimensional and performance criteria, including Class 6g thread fit for standard metric tolerance and fully threaded M10x1.5 coarse thread. It meets ASME B18.2.3.9M specifications for dimensional consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use in global markets.
