Key Features & Benefits at a Glance
- Exceptional tensile strength of 110,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Left-hand thread design provides secure fastening in applications where right-hand rotation could cause loosening, such as rotating machinery.
- Class 8.8 strength grade steel offers superior durability and resistance to deformation under heavy loads, extending service life.
- Fully threaded shank maximizes grip and holding power across the entire length, enhancing stability in assembled components.
- External hex drive and hex head allow for easy installation and removal with standard tools, improving assembly efficiency.
- Class 6g thread fit ensures precise, consistent engagement with nuts or tapped holes, minimizing play and vibration-induced loosening.
- RoHS 3 and REACH compliance guarantees environmental safety and regulatory adherence for use in global industrial markets.
Professional Applications & Engineering Value
This M10 left-hand hex head screw is engineered to address critical challenges in industrial settings where reverse-thread fastening is essential. Made from Class 8.8 steel with a Rockwell C21 hardness, it resists wear and corrosion in demanding environments like machinery, automotive assemblies, and conveyor systems. The coarse thread with a 1.5 mm pitch and fully threaded design ensures rapid installation and robust clamping force, preventing unintentional loosening from counter-clockwise motion. Its compliance with ASME B18.2.3.1M and ISO 898-1 standards assures dimensional accuracy and interoperability, making it a reliable choice for engineers seeking longevity and safety in left-hand thread metric applications.
Specification Summary & Compliance
This screw features a metric M10x1.5 coarse thread with Class 6g thread fit for precise tolerance, a length of 30 mm, and a hex head width of 17 mm. It meets ASME B18.2.3.1M and ISO 898-1 specifications for dimensional and mechanical properties, and is certified RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring it adheres to environmental and health regulations for industrial use.
