Professional Applications & Engineering Value

These M6 flat head screws combine security and sealing capabilities in a single 18-8 stainless steel fastener, solving critical engineering challenges across multiple industries. The tamper-resistant Torx T30 drive prevents vandalism and unauthorized disassembly in public infrastructure, transportation, and industrial equipment, while the Buna-N rubber O-ring creates reliable seals in hydraulic systems, pneumatic controls, and outdoor enclosures exposed to weather elements. The passivated finish enhances corrosion resistance beyond standard stainless steel, making these screws ideal for marine applications, food processing equipment, and chemical environments where both security and durability are paramount. The metric coarse thread with Class 6g tolerance ensures consistent performance in high-vibration machinery and automated assembly processes.

Specification Summary & Compliance

This M6 x 1mm flat head screw features precision Class 6g thread fit according to metric standards with fully threaded 25mm length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The 90° countersink angle and 13.43mm head diameter maintain proper flush mounting, while the O-ring temperature range of -40° to 225°F supports operation in extreme conditions.
