Key Features & Benefits at a Glance
- Exceptional corrosion resistance thanks to 18-8 stainless steel construction, ideal for harsh or outdoor industrial environments.
- High tensile strength of 80,000 psi ensures reliable performance in demanding, high-stress applications.
- Coarse 2.5mm pitch thread provides faster assembly and reduced risk of cross-threading.
- Durable external hex drive and hex head allows for high torque application with standard tools, minimizing stripping.
- Partially threaded design offers optimal clamping force where a non-threaded shank is required.
- Precise Class 6g thread fit guarantees consistent and secure mating with nuts and tapped holes.
- Compliance with DIN 931, RoHS 3, and REACH ensures material quality and environmental safety for global projects.
Professional Applications & Engineering Value
This M18 hex head screw is engineered to solve critical challenges in structural and machinery assembly. Its 18-8 stainless steel material provides excellent resistance to rust and oxidation, making it suitable for applications in chemical processing, marine equipment, and food machinery where corrosion resistance is paramount. The coarse metric thread and external hex drive enable quick, secure fastening in heavy-duty frameworks, construction steelwork, and industrial machinery, reducing installation time and improving joint integrity. The partially threaded shank ensures that the unthreaded portion bears shear loads effectively, preventing loosening under vibration. Fully compliant with DIN 931, this screw delivers reliable performance and long-term durability in demanding engineering environments.
Specification Summary & Compliance
This fastener features a Metric M18 x 2.5mm coarse thread with a Class 6g thread fit for standard tolerance, a length of 200 mm, and a partially threaded design. It is manufactured in accordance with DIN 931 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets international environmental and safety standards for industrial use.
