  • Wide operating temperature range (-40° to 185°F) allows for stable performance in both extreme cold and moderate heat conditions.
  • 90° countersink angle and flat head design enables a flush, low-profile installation that minimizes protrusion and improves aesthetic finish.
  • Fully threaded coarse pitch (0.7mm) offers quick assembly and strong holding power in plastic or soft materials.
  • Compliance with ASME B18.6.7M, RoHS 3, and REACH ensures adherence to industry standards and environmental safety regulations.
  • Slotted drive style facilitates easy installation and removal with standard tools, streamlining maintenance and adjustments.

Professional Applications & Engineering Value

These M4 nylon plastic flat head screws are engineered to address common industrial challenges such as electrical insulation, weight reduction, and corrosion resistance. Made from durable nylon material, they prevent galvanic corrosion when used with dissimilar metals and provide excellent dielectric properties, making them ideal for electrical enclosures, automotive components, and consumer electronics. The fully threaded coarse pitch and Class 6g precision ensure reliable fastening in plastic assemblies, reducing strip-out risks. With a temperature range of -40° to 185°F, they maintain integrity in varying environments, while the slotted drive and 90° countersink allow for seamless integration in designs requiring flush surfaces.

Specification Summary & Compliance

This screw features a metric M4 x 0.7mm coarse thread with Class 6g thread fit for dimensional accuracy, and a length of 12mm. It complies with ASME B18.6.7M standards for mechanical fasteners, ensuring consistent quality and performance. Additionally, it is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations for hazardous substances.
