S-97870A218 M6 x 20 mm Sealing Tamper-Resistant Torx Flat Head Screws

Key Features & Benefits at a Glance

• Tamper-resistant Torx T30 drive prevents unauthorized access, enhancing equipment security in public or high-risk environments.
• Integrated Buna-N rubber O-ring provides reliable sealing up to 1500 psi, protecting components from moisture, dust, and contaminants.
• 18-8 stainless steel construction with passivated finish offers superior corrosion resistance, ensuring long-term durability in harsh industrial conditions.
• Undercut flat head design allows for flush mounting, reducing snag risks and improving aesthetic integration in precision assemblies.
• Class 6g thread fit with M6x1 coarse pitch ensures easy installation and secure fastening, minimizing cross-threading in high-vibration applications.
• Full compliance with RoHS 3 and REACH standards guarantees environmental safety and regulatory acceptance for global supply chains.
• Wide O-ring temperature tolerance (-40° to 225° F) maintains seal integrity across diverse operating climates, from freezing outdoor to heated indoor settings.

Professional Applications & Engineering Value

Engineered for security-critical and sealed assemblies, this M6 flat head screw addresses common industrial challenges like tampering and environmental ingress. The tamper-resistant Torx T30 drive deters vandalism in public infrastructure, while the Buna-N rubber O-ring creates a robust seal against fluids and particulates—ideal for electrical enclosures, machinery panels, and automotive components. Made from 18-8 stainless steel with a passivated finish, it resists rust and chemical exposure in humid or corrosive settings. The undercut flat head sits seamlessly in countersunk holes, preventing protrusion in compact designs. By combining metric coarse threading (M6x1) for quick installation and a 1500 psi pressure rating, it streamlines maintenance in high-pressure systems like hydraulic controls or pneumatic devices.

Specification Summary & Compliance

This screw adheres to metric ISO standards with M6x1 coarse threads and a Class 6g tolerance for precise fit. The 90° countersink angle and 13.43 mm head diameter ensure compatibility with standard flat head applications. It is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting stringent environmental and safety regulations for industrial use.
