S-90909A718 M4 x 10 mm ISO 7380 Stainless Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh chemical and marine environments.
• Enhanced durability and load distribution thanks to the integrated flange, eliminating the need for a separate washer.
• Secure and reliable fastening with a Class 6g thread fit, ensuring precise engagement and vibration resistance in coarse thread applications.
• High tensile strength of 70,000 psi for robust performance in demanding mechanical assemblies.
• Easy installation and removal with a 2.5 mm hex drive, providing a secure grip and reducing tool slippage.
• Improved chemical resistance and surface protection from the passivated finish, extending the screw's service life.
• Compliance with international standards including ISO 7380, ensuring consistent quality and interchangeability.

Professional Applications & Engineering Value

This M4 flanged hex button head screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly efficiency. Made from 316 stainless steel with a passivated finish, it offers exceptional resistance to chlorides and acidic conditions, making it perfect for marine equipment, chemical processing plants, and food-grade machinery. The integrated flange provides a larger bearing surface, distributing clamp load effectively and preventing surface damage, while the coarse metric thread (M4 x 0.7mm) ensures quick installation and reliable holding power in softer materials or high-vibration settings like automotive and electronics assemblies. Fully threaded for maximum grip, this screw simplifies inventory by combining washer and screw functions, reducing part count and speeding up production lines.

Specification Summary & Compliance

This screw adheres to precise dimensional standards with a Class 6g thread fit and ISO 7380 specifications for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial applications. The manufacturing process meets rigorous quality controls for metric coarse threading and material integrity, supporting reliable use in global engineering projects.
