S-90236A102 M2 x 4 mm ISO 14581 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated alloy steel construction, extending service life in demanding industrial environments
• Superior torque transmission and reduced cam-out thanks to the T6 Torx drive, ensuring reliable installation and maintenance
• High tensile strength and durability from Class 8.8 rating and Rockwell C22 hardness, preventing stripping and failure under load
• Optimal flush mounting and space efficiency with the standard flat head profile and 90° countersink angle for sleek, secure assemblies
• Consistent and precise thread engagement due to Class 6h thread fit and coarse 0.4mm pitch, enabling quick, vibration-resistant fastening
• Full-length threading for maximum grip across the entire 4mm length, distributing stress evenly and enhancing joint integrity
• Global compliance and reliability with ISO 14581 standards, RoHS 3, and REACH, ensuring safe, high-quality performance in regulated applications

Professional Applications & Engineering Value

Engineered for precision assemblies, these M2 flat head Torx screws address common industrial challenges like vibration loosening and corrosion. The zinc-plated alloy steel material provides a protective barrier against moisture and chemicals, ideal for electronics, automotive, and machinery where environmental factors are a concern. With a Class 8.8 strength grade and fully threaded design, they deliver robust clamping force in tight spaces, reducing the need for frequent retightening. The T6 Torx drive minimizes tool slippage, enhancing efficiency in high-volume production lines. Compliant with ISO 14581, these screws ensure dimensional accuracy and reliability, making them a trusted choice for engineers seeking durable, metric fasteners that meet rigorous industry demands.

Specification Summary & Compliance

This screw adheres to precise metric dimensions, including a 4mm length, 3.8mm head diameter, and Class 6h thread fit for consistent tolerance. It meets ISO 14581 manufacturing standards, ensuring uniformity in thread form and head profile. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms it is free from hazardous substances, supporting safe use in global markets. The right-hand coarse thread with 0.4mm pitch and 90° countersink angle further aligns with industry specifications for reliable performance.
