S-97646A336 M8 x 45 mm 18-8 Stainless Steel Serrated-Flange Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and reducing maintenance costs.
• Exceptional mechanical strength with 100,000 psi tensile strength and Rockwell B100 hardness for reliable performance under high stress.
• Enhanced locking and vibration resistance provided by the serrated flange, eliminating the need for a separate washer and preventing loosening.
• Efficient installation and removal with the external hex drive and coarse M8 x 1.25mm thread, allowing for quick assembly with standard tools.
• Precise and reliable fit ensured by the Class 6g thread tolerance, providing consistent performance in metric assemblies.
• Full-threaded design for maximum grip and load distribution along the entire 45mm length, enhancing joint integrity.
• Compliance with environmental and safety standards including RoHS 3 and REACH, ensuring suitability for regulated industrial markets.

Professional Applications & Engineering Value

This M8 hex head screw is engineered to solve critical challenges in industrial assembly, where vibration, corrosion, and high tensile loads are common. The 18-8 stainless steel material provides excellent resistance to rust and chemical exposure, making it ideal for outdoor equipment, marine applications, and food processing machinery. The integrated flange with serrations acts as a built-in lock washer, securely fastening components without back-out, which is vital for automotive subframes or heavy machinery subjected to constant motion. Its coarse thread pitch and external hex drive enable rapid installation, reducing labor time in production lines. With a 100,000 psi tensile strength, it ensures durable connections in structural frameworks, supporting long-term reliability and minimizing downtime for maintenance.

Specification Summary & Compliance

This screw adheres to metric thread standards with an M8 x 1.25mm coarse thread and Class 6g tolerance for precise fit. It is fully threaded and features a flange diameter of 18 mm. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
