Key Features & Benefits at a Glance
- Exceptional durability with Class 10.9 strength grade and 140,000 psi tensile strength, ensuring reliable performance in high-stress applications.
- Superior corrosion resistance from zinc-plated alloy steel, extending service life in harsh industrial environments.
- Precise and secure fastening with M8 coarse thread (1.25mm pitch) and Class 6g fit, reducing assembly errors and vibration loosening.
- Easy installation and removal using a standard 5mm hex drive, saving time and labor in maintenance and assembly.
- Full threading for maximum grip along the 25mm length, providing consistent clamping force across joined materials.
- High hardness (Rockwell C32) resists wear and deformation, maintaining fastener integrity under repeated use.
- Compliance with ISO 7380 and environmental standards (RoHS 3, REACH) ensures safety and regulatory acceptance in global markets.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, this M8 x 1.25mm Class 10.9 zinc-plated alloy steel rounded head screw addresses critical fastening challenges. The metric coarse thread and Class 6g thread fit deliver precise alignment and robust holding power, minimizing the risk of strip-out in metals or composites. With a fully threaded design and 5mm hex drive, it enables quick, tool-friendly installation in confined spaces, such as machinery, automotive assemblies, and structural frameworks. The zinc plating provides a protective barrier against moisture and chemicals, reducing downtime due to corrosion. Ideal for heavy-duty applications requiring high tensile strength and longevity, this screw ensures operational reliability and cost-efficiency in engineering projects.
Specification Summary & Compliance
This screw adheres to ISO 7380 standards, with precise Class 6g thread fit and M8 x 1.25mm coarse thread dimensions for consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory approval. Manufactured from zinc-plated alloy steel, it maintains Class 10.9 strength grade, Rockwell C32 hardness, and 140,000 psi tensile strength for reliable fastening in industrial use.
