• Reliable coarse threading with Class 6g fit and 0.25 mm pitch for faster installation and secure holding power in various materials.
• High tensile strength of 70,000 psi provides robust fastening integrity for demanding small-scale assemblies.
• Broad industrial compliance meeting DIN 963 standards, RoHS 3, and REACH, ensuring safety and regulatory acceptance.
• Simplified manual installation with a standard slotted drive, offering tooling flexibility and ease of use in tight spaces.
• Fully threaded design from head to tip maximizes grip length and adjustability in shallow or deep applications.

Professional Applications & Engineering Value

These M1.2 flat head screws are engineered to address critical challenges in precision industries like electronics, medical devices, and instrumentation. The 18-8 stainless steel material, combined with a passivated finish, effectively combats corrosion and oxidation, ensuring long-term reliability in humid or chemically exposed settings. The fully threaded metric coarse thread (0.25 mm pitch) and Class 6g tolerance enable quick, vibration-resistant fastening in brittle substrates or compact assemblies, reducing the risk of cross-threading and material stress. The flat head profile with a 90° countersink allows for seamless integration into chamfered holes, maintaining aerodynamic and aesthetic surfaces while providing a secure, low-profile hold. This design is particularly valuable in applications where space is limited and a flush finish is mandatory for both functional and safety reasons.

Specification Summary & Compliance
