- High tensile strength of 70,000 psi provides reliable, heavy-duty fastening for demanding applications.
- Secure, slip-resistant installation with a 2.5 mm hex drive, allowing for precise torque application and easy assembly.
- Consistent thread engagement due to Class 6g fit and coarse thread pitch, minimizing cross-threading risks.
- Versatile, space-saving design with a low-profile button head, ideal for compact assemblies without compromising strength.
- Full threading along the 40 mm length ensures maximum grip and adjustability in various material thicknesses.
Professional Applications & Engineering Value
This M4 flanged button head screw is engineered to address common industrial fastening challenges, such as vibration loosening and corrosion-induced failure. The 18-8 stainless steel construction, combined with a passivated finish, offers exceptional resistance to rust and chemicals, making it suitable for outdoor equipment, automotive assemblies, and machinery exposed to moisture. The hex drive and wide flange provide stable torque transmission and distribute clamping force evenly, preventing joint failure in high-stress environments. Its fully threaded design and coarse thread pitch enable quick installation and reliable holding power in metals and plastics, streamlining production while reducing maintenance needs.
Specification Summary & Compliance
This screw adheres to ISO 7380 standards, with precise metric thread specifications including M4 size, 0.7 mm pitch, and Class 6g thread fit for consistent dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability in industrial applications.
