Professional Applications & Engineering Value

This M4 metric screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and installation efficiency. The 18-8 stainless steel material, combined with a passivated finish, offers exceptional resistance to rust and chemicals, making it suitable for outdoor equipment, machinery, and electronics exposed to moisture. The flanged button head eliminates the need for a separate washer, distributing clamp load evenly and preventing pull-through in softer materials. With a coarse thread pitch and fully threaded design, it ensures faster assembly and strong grip in plastics and metals, reducing the risk of cross-threading. This screw is ideal for applications requiring a low-profile, high-strength metric fastener that meets rigorous ISO 7380 specifications for consistent quality and performance.

Specification Summary & Compliance

This product adheres to precise dimensional standards, including a Class 6g thread fit for metric coarse threads, ensuring compatibility and ease of use. It conforms to ISO 7380 for dimensional accuracy and performance. Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for various industrial applications.
