  • High tensile strength of 130,000 psi ensures reliable performance under heavy loads and vibration
  • Flanged design with serrations provides enhanced load distribution and prevents loosening without separate washers
  • Class 6g thread fit guarantees precise mating with nuts and threaded holes for consistent assembly quality
  • External hex drive allows for high-torque installation using standard tools, reducing assembly time
  • Fully threaded M10x1.5mm coarse pitch enables faster installation and stronger holding power in various materials
  • Rockwell C27 hardness maintains thread integrity and prevents stripping during repeated use

Professional Applications & Engineering Value

This M10 hex head screw with black-oxide steel construction addresses critical fastening challenges in machinery, automotive, and heavy equipment applications. The flanged design with serrations eliminates the need for additional washers while providing superior anti-rotation properties, reducing component count and assembly complexity. The fully threaded metric coarse thread (1.5mm pitch) ensures rapid installation in steel frameworks and cast components, while the external hex drive accommodates high torque requirements for permanent joints. Engineered with Rockwell C27 hardness and 130,000 psi tensile strength, it withstands dynamic loads and vibration fatigue in industrial environments, making it ideal for structural connections, motor mounts, and conveyor systems where reliability is paramount.

Specification Summary & Compliance

This metric hex head screw features M10x1.5mm coarse threads with Class 6g tolerance per ISO standards, ensuring precise thread engagement. The 16mm length and 21mm flange diameter provide optimal clamping range. Manufactured from hardened steel with black-oxide surface treatment, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use in global industrial supply chains.
