S-97870A179 M3 x 10 mm Sealing Tamper-Resistant Torx Flat Head Screws

Key Features & Benefits at a Glance

• Tamper-Resistant Security: The specialized T10 Torx drive deters unauthorized removal, providing enhanced protection for sensitive equipment and public-access applications.
• Reliable Pressure Sealing: The integrated Buna-N rubber O-ring creates a robust seal capable of withstanding pressures up to 1500 psi, preventing fluid and gas leaks in demanding environments.
• Superior Corrosion Resistance: Manufactured from 18-8 Stainless Steel with a passivated finish, this screw offers excellent durability against rust and corrosion, extending service life in harsh conditions.
• Optimized Seating & Clamping: The undercut flat head profile allows the head to sit flush with the surface, ensuring a clean finish and improved clamping force.
• Precision Thread Engagement: The Class 6g thread fit and coarse M3 x 0.5 mm threading provide reliable, high-strength fastening with a tensile strength of 70,000 psi.
• Broad Temperature Compatibility: The Buna-N O-ring maintains its sealing integrity across a wide temperature range from -40° to 225° F, suitable for various operational climates.
• Global Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring the screw is free from hazardous substances and safe for use in regulated industries.

Professional Applications & Engineering Value

This M3 flat head screw is engineered to solve critical challenges in industrial assembly where security and environmental sealing are paramount. The combination of a tamper-resistant Torx drive and an integrated Buna-N O-ring makes it an ideal choice for enclosures, control panels, and machinery that require protection against both unauthorized access and ingress of moisture, dust, or pressurized fluids. The 18-8 stainless steel construction and passivated finish provide long-term corrosion resistance, essential for outdoor, marine, or chemical-exposed applications. The undercut flat head design ensures a flush mount, preventing snagging and contributing to a professional, aerodynamic finish. This fastener delivers reliable performance in automotive, electronics, and telecommunications sectors, where maintaining a sealed and secure environment is critical for operational integrity.
