S-90236A111 M2.5 x 5 mm ISO 14581 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating, extending service life in demanding industrial environments.
• High-strength Class 8.8 rating ensures reliable performance and resistance to loosening under vibration and load.
• Enhanced torque transmission and strip-resistance provided by the T8 Torx drive, enabling secure installations.
• Precision Class 6h thread fit guarantees consistent engagement and reduces the risk of cross-threading.
• Full threading along the 5 mm length offers maximum grip and holding power in various materials.
• Rockwell C22 hardness provides excellent durability and wear resistance for repeated use.
• Compliance with ISO 14581, RoHS 3, and REACH ensures product quality, safety, and environmental responsibility.

Professional Applications & Engineering Value

These M2.5 flat head screws are engineered from zinc-plated alloy steel to address common challenges in precision assemblies, such as corrosion in humid or chemical-exposed settings. The Torx T8 drive minimizes cam-out, allowing higher torque application without damaging the fastener head, which is critical in automated or high-volume production lines. With a coarse 0.45 mm pitch and fully threaded design, they provide quick insertion and strong retention in metals and plastics, reducing assembly time and improving joint integrity. Ideal for electronics, automotive components, and machinery where high-strength Class 8.8 performance and regulatory compliance are mandatory.

Specification Summary & Compliance

This fastener features a metric M2.5 x 0.45 mm thread with Class 6h tolerance for precise fit, right-hand thread direction, and a standard 90° countersink angle. It conforms to ISO 14581 for dimensional accuracy and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
