• Full threading along the 20mm length provides maximum grip and adjustability, enhancing load distribution in fastened components.
• Standard 90° countersink angle and flat head design enables flush mounting for a smooth, professional finish and improved aerodynamics.
• Compliance with ASME B18.6.7M guarantees dimensional accuracy and interchangeability, reducing assembly errors and downtime.
• RoHS 3 and REACH compliance ensures environmental safety and regulatory adherence for global supply chain integration.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M8 flat head screws in polycarbonate plastic address critical challenges like corrosion, electrical insulation, and weight reduction. The clear material allows for easy visual verification of thread engagement and component alignment, while the fully threaded design with Class 6g metric threads ensures robust holding power in plastics, composites, and thin-metal assemblies. Ideal for electronics enclosures, automotive interiors, and medical devices, these slotted drive screws simplify maintenance with standard tools, and their high-temperature resistance up to 210°F prevents deformation in thermally dynamic environments. By combining ASME B18.6.7M precision with regulatory compliance, they minimize failure risks and support efficient, repeatable installations.

Specification Summary & Compliance

This screw adheres to metric dimensions with a thread size of M8, pitch of 1.25mm (coarse spacing), and Class 6g thread fit for standard tolerance. It meets ASME B18.6.7M specifications for flat head profile and 90° countersink angle, ensuring consistent quality. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) for hazardous substance restrictions, supporting safe and sustainable usage.
