Key Features & Benefits at a Glance
- Exceptional tensile strength with Class 8.8 rating (110,000 PSI) for reliable performance in high-stress applications
- Superior corrosion resistance due to zinc-plated finish, extending service life in harsh environments
- Left-hand threading provides secure fastening in applications where standard right-hand threads may loosen under rotational forces
- Precision Class 6h thread fit ensures consistent engagement and reduces the risk of cross-threading during installation
- Full threading along the 35mm length offers maximum grip and load distribution across the entire fastener
- External hex drive design allows for high-torque installation with standard tools and easy visual inspection
- Rockwell C21 hardness maintains thread integrity and prevents stripping under repeated use
Professional Applications & Engineering Value
This M10 left hand hex head screw delivers critical engineering solutions where reverse-rotation applications demand specialized metric coarse threading. The Class 8.8 steel construction provides the necessary tensile strength for heavy machinery, conveyor systems, and rotating equipment where vibration-induced loosening is a concern. The zinc-plated finish protects against corrosion in industrial environments, while the external hex drive enables secure installation in confined spaces. With fully threaded design and 1.5mm pitch coarse thread, this fastener ensures rapid assembly and disassembly in maintenance-intensive applications, reducing downtime and improving operational efficiency.
Specification Summary & Compliance
Manufactured to precise metric dimensions with Class 6h thread fit tolerance ensuring consistent performance. Complies with ASME B18.2.3M and ISO 898-1 standards for dimensional accuracy and mechanical properties. The zinc-plated finish meets industry corrosion protection requirements while maintaining Rockwell C21 hardness for durability. Suitable for applications requiring left-hand thread direction with M10 x 1.5mm coarse thread spacing and 35mm length.
