S-90166A149 M8 x 12 mm DIN 6921 Stainless Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term durability.
• Simplified installation and removal thanks to the external hex drive and flanged design, which eliminates the need for a separate washer.
• Reliable, high-strength performance with a tensile strength of 100,000 psi, ensuring secure fastening under significant load.
• Optimized for quick assembly with a coarse thread pitch (1.25mm) and Class 6g thread fit, providing excellent engagement and vibration resistance.
• Guaranteed dimensional consistency and interchangeability by conforming to the precise DIN 6921 standard for metric hex head screws.
• Broad industrial compliance meeting RoHS 3 and REACH regulations, ensuring safety and environmental responsibility.
• Full-threaded design for maximum grip and holding power along the entire 12mm length of the screw.

Professional Applications & Engineering Value

This M8 flanged hex head screw is engineered to solve common industrial fastening challenges. The integrated flange distributes clamping force over a wider area, reducing surface pressure and preventing loosening from vibration, making it superior to standard hex head screws in assembly line and machinery applications. Manufactured from 18-8 Stainless Steel, it provides excellent resistance to rust and corrosion, which is critical for outdoor equipment, food processing machinery, and marine applications. The coarse metric thread and Class 6g thread fit ensure rapid, reliable installation and a secure hold in various materials, from steel to aluminum. This combination of a robust external hex drive and a fully threaded shank delivers exceptional tensile strength and durability for demanding industrial fasteners requirements.

Specification Summary & Compliance

This screw features an M8 x 1.25mm coarse thread with a Class 6g thread fit and right-hand thread direction, ensuring high dimensional accuracy per standard metric tolerances. The manufacturing and quality are strictly controlled to meet the DIN 6921 specification for flanged hex head screws. Furthermore, this product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to strict environmental and safety standards for industrial components.
