Key Features & Benefits at a Glance

  • Enhanced Component Protection – Permanent swivel tip with 9° maximum angle prevents surface damage and marring on delicate components during installation
  • Superior Thread Engagement – Class 6g thread fit ensures precise mating with standard metric nuts and threaded holes for reliable connections
  • High-Torque Installation Capability – 2.5mm hex drive design allows for substantial tightening force without head protrusion in confined spaces
  • Exceptional Mechanical Durability – Alloy steel construction with Rockwell C39 hardness maintains clamping force under vibration and heavy loads
  • Optimized for Industrial Environments – Coarse 0.8mm pitch threads resist clogging with debris and enable quicker installation in production settings
  • Regulatory Compliance Assurance – RoHS 3 compliance with exemption 6(a) meets international environmental standards for industrial applications
  • Space-Efficient Design – Headless configuration with 24.5mm length provides maximum thread engagement in compact assemblies

Professional Applications & Engineering Value

This M5 set screw delivers critical engineering solutions for precision industrial applications where component alignment and surface protection are paramount. The permanent swivel tip eliminates galling and surface deformation on shafts, gears, and pulleys while maintaining consistent clamping force. Manufactured from alloy steel with Rockwell C39 hardness, it withstands rotational stresses in motor assemblies and vibrating machinery. The hex headless design with 2.5mm drive accommodates tight clearance requirements in robotics, automotive subassemblies, and precision equipment. Class 6g thread tolerance ensures reliable performance in high-cycle manufacturing environments where dimensional consistency is critical for maintenance-free operation.

Specification Summary & Compliance

This metric set screw features M5x0.8mm coarse threads with Class 6g thread fit per ISO standards, ensuring dimensional accuracy for industrial applications. The 24.5mm length provides optimal engagement depth while the permanent swivel tip maintains 9° maximum angular adjustment. Manufactured from high-strength alloy steel and compliant with RoHS 3 (2015/863/EU) regulations under exemption 6(a) for lead as an alloying element in steel, meeting international environmental requirements for industrial components.
