S-93140A220 M4 x 6 mm ASME B18.6.7M Plastic Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional optical clarity for applications requiring visibility or light transmission without compromising structural integrity.
• Reliable performance across extreme temperatures, maintaining integrity from -40°F to 210°F for use in varied environmental conditions.
• Precision Class 6g thread fit ensures consistent, secure fastening with reduced risk of cross-threading in metric assemblies.
• Standard 90° countersink angle allows for a flush, professional finish that minimizes protrusion and snagging risks.
• Durable polycarbonate construction offers excellent impact resistance and longevity, ideal for non-corrosive and non-conductive needs.
• Full threading along the 6mm length provides maximum grip and holding power across the entire engagement surface.
• Broad regulatory compliance including ASME B18.6.7M, RoHS 3, and REACH, ensuring safety and suitability for global markets.

Professional Applications & Engineering Value

Engineered for precision, this M4 flat head screw in clear polycarbonate addresses critical needs in electronics, medical devices, and display assemblies where metal fasteners are unsuitable. The slotted drive offers simple, tool-compatible installation, while the fully threaded design and coarse 0.7mm pitch enhance assembly speed and pull-out resistance. Its temperature-resistant properties ensure stability in environments subject to thermal cycling, and the non-conductive, corrosion-proof material eliminates risks of galvanic corrosion or electrical interference. Ideal for securing panels, lenses, or components in sensitive equipment, this screw combines optical transparency with mechanical reliability, streamlining both prototyping and production.

Specification Summary & Compliance

This screw adheres to metric system dimensions: M4 x 0.7mm pitch, 6mm length, with a Class 6g thread fit per ISO standards for consistent engagement. The flat head features a standard 90° countersink angle and 9.4mm head diameter. Manufacturing and quality are governed by ASME B18.6.7M, ensuring dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances and safe for industrial use.
