S-90550A119 M4 x 6 mm Venting Stainless Steel Hex-Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for humid or chemically exposed environments.
• Secure, flush installation thanks to the standard 90° flat head profile and 2.5mm hex drive for high-torque application.
• Reliable coarse thread engagement with a 0.7mm pitch and Class 6g fit, ensuring quick assembly and vibration resistance.
• Maximum holding power from the fully threaded M4 design, providing consistent grip along the entire 6mm length.
• Pressure and debris management enabled by the integrated 1.17mm vent diameter, preventing air or particle entrapment.
• Global regulatory compliance with RoHS 3 and REACH, making them safe for use in regulated industrial and electronic applications.

Professional Applications & Engineering Value

This M4 flat head screw is engineered to solve critical challenges in precision assembly. The 18-8 stainless steel material resists oxidation and chemical degradation, making it suitable for electronics, marine hardware, and food processing equipment where moisture is a concern. The fully threaded body and coarse 0.7mm pitch enable faster driving and higher pull-out strength in soft materials or pre-tapped holes. The vented design is particularly valuable in sealed systems—such as sensors or enclosures—allowing pressure equalization and preventing vacuum lock. Combined with a 2.5mm hex drive, these screws deliver reliable, repeatable fastening in automated or high-vibration settings.

Specification Summary & Compliance

This metric screw conforms to Class 6g thread fit tolerances, ensuring dimensional accuracy and interchangeability. It features a standard M4 x 0.7mm coarse thread and is fully threaded over its 6mm length. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances.
