Key Features & Benefits at a Glance

  • Enhanced durability with 6061 aluminum construction providing 40,000 psi tensile strength and Rockwell B40 hardness for reliable performance in demanding applications
  • Secure installation through 2.5mm hex drive design that prevents stripping and ensures consistent torque application
  • Superior load distribution thanks to the integrated flange that eliminates the need for separate washers and reduces surface pressure
  • Quick assembly efficiency with coarse M4 x 0.7mm thread pitch enabling faster installation in various materials
  • Precise thread engagement through Class 6g tolerance ensuring consistent fit and reliable fastening performance
  • Complete thread coverage with fully threaded design providing maximum grip strength along the entire 10mm length
  • Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in industrial environments

Professional Applications & Engineering Value

These flanged button head screws deliver exceptional engineering value in applications where weight reduction and corrosion resistance are critical. The 6061 aluminum construction provides an optimal strength-to-weight ratio while the integrated flange design distributes clamping force effectively, preventing damage to softer materials. The M4 metric coarse thread with Class 6g tolerance ensures reliable performance in industrial assembly environments, particularly in electronics enclosures, machinery panels, and automotive components where vibration resistance and repeated disassembly are common requirements. The rounded button head profile offers a finished appearance while the hex drive maintains tool engagement during high-torque applications.

Specification Summary & Compliance

This metric screw features precise M4 x 0.7mm coarse threading with Class 6g thread fit tolerance according to ISO standards, ensuring consistent performance in industrial fastening applications. The manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(b)-II for lead as an alloying element in aluminum, and maintains REACH (EC 1907/2006) compliance as of January 17, 2023. The fully threaded design with 10mm length and integrated flange provides complete specification adherence for professional industrial use.
