Key Features & Benefits at a Glance
- Exceptional tensile strength of 150,000 PSI ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-phosphate steel coating extends service life in harsh industrial environments.
- High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Integrated flange design eliminates the need for separate washers, simplifying installation and improving load distribution.
- Class 10.9 strength grade guarantees consistent performance for critical bolting applications requiring high reliability.
- Coarse metric threading (M12 x 1.75mm) enables faster installation and better resistance to vibration loosening.
- Full threading along the 35mm length offers maximum adjustability and grip strength in various material thicknesses.
Professional Applications & Engineering Value
These M12 hex head screws deliver critical engineering solutions where high tensile strength and corrosion resistance are paramount. The black-phosphate steel construction provides superior protection against rust and chemical exposure in demanding environments like heavy machinery, structural steel frameworks, and automotive assemblies. The flanged design distributes clamping force evenly, preventing surface damage while the Class 6g thread fit ensures precise engagement with mating components. With 150,000 PSI tensile strength and Rockwell C32 hardness, these metric coarse thread screws maintain integrity under extreme vibration and dynamic loads, making them ideal for industrial equipment, construction projects, and transportation applications where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to precise metric dimensions with Class 6g thread tolerance for consistent fit and performance. These hex head screws comply with ASME B18.2.3.9M specifications and meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The 35mm length and 26.6mm flange diameter provide standardized dimensions for interchangeable use across industrial applications.
