S-90550A112 M2.5 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, ensuring long-term reliability in humid or demanding environments.
• Enhanced assembly efficiency via the hex drive design, allowing for high-torque application with a standard 1.5mm hex key.
• Secure, flush mounting thanks to the flat head with 90° countersink angle, ideal for applications requiring a smooth surface finish.
• Optimized airflow and pressure equalization through the fully threaded, vented profile, preventing pressure buildup in sensitive assemblies.
• Consistent and reliable thread engagement with Class 6g coarse thread fit, ensuring easy installation and robust holding power.
• Broad industrial compliance by meeting RoHS 3 and REACH regulations, making them suitable for global supply chains and sensitive applications.
• Durable, fully threaded design providing maximum grip along the entire 6mm length for enhanced load distribution.

Professional Applications & Engineering Value

This M2.5 metric flat head screw is engineered to address critical assembly challenges in electronics, automotive, and precision machinery. The 18-8 stainless steel offers excellent resistance to oxidation and corrosion, which is vital for components exposed to moisture or chemicals. The hex drive ensures that high torque can be applied without slippage, reducing the risk of damage during installation. The vented design is particularly valuable in enclosed systems, such as sensors or housings, where pressure differentials could affect performance. Combined with a fully threaded body and coarse thread pitch, these screws provide rapid installation and secure fastening in materials where fine threads might strip. This makes them an ideal stainless steel fastener for applications demanding both mechanical strength and environmental durability.
