Key Features & Benefits at a Glance

  • Exceptional chemical and corrosion resistance due to polypropylene construction, ideal for harsh industrial environments
  • Reliable 4500 psi tensile strength provides secure fastening for a wide range of non-structural applications
  • Broad temperature tolerance from -20° to 180° F ensures performance stability in varying operational conditions
  • Precise Class 6g thread fit guarantees smooth installation and consistent engagement with mating components
  • Standard 5mm hex drive socket head allows for high-torque installation and a clean, flush finish
  • Full compliance with DIN 912, RoHS 3, and REACH ensures adherence to international mechanical and environmental safety standards
  • Lightweight and non-conductive properties make it perfect for electrical and weight-sensitive assemblies

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M6 socket head cap screw solves common challenges where metal fasteners fail. Its Polypropylene Plastic body is inherently corrosion resistant, eliminating the risk of rust and galvanic corrosion in chemical, marine, or outdoor settings. The fully threaded design with a 1mm coarse pitch and Class 6g thread fit ensures rapid assembly and vibration resistance, while the socket head with a 5mm hex drive provides a secure tool grip for high-torque tightening in confined spaces. This makes it an ideal plastic fastener for electronics enclosures, food processing equipment, and other assemblies requiring a non-magnetic, insulating, and lightweight solution.

Specification Summary & Compliance

This screw conforms to the dimensional and mechanical specifications of DIN 912 with a Class 6g thread tolerance for metric coarse threads. It is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental regulations for hazardous substances. The specified M6 x 1mm thread and 25mm length ensure dimensional accuracy for reliable interchangeability.
