S-3638N127 M10 x 40 mm DIN 561B Set Screws

Key Features & Benefits at a Glance

• High tensile strength with Class 8.8 rating ensures reliable performance under demanding loads and vibration
• Precision Class 6g thread fit provides smooth assembly and consistent clamping force in repetitive applications
• Extended tip design (5mm length) creates positive engagement and prevents component slippage in critical assemblies
• Rockwell C20 hardness delivers excellent wear resistance and maintains thread integrity through multiple installation cycles
• External hex drive with 13mm head allows high torque application using standard tools while resisting stripping
• Coarse M10x1.5 thread pitch enables rapid installation and reduced assembly time in production environments
• Full regulatory compliance including RoHS 3 and REACH ensures environmental responsibility and global market acceptance

Professional Applications & Engineering Value

This M10 metric set screw with Class 8.8 strength rating addresses critical challenges in industrial machinery, automotive components, and heavy equipment assembly. The steel construction with controlled Rockwell C20 hardness provides optimal balance between toughness and machinability, resisting deformation under cyclic loading conditions. The extended tip design with precise diameter control ensures positive location in shaft collars, gears, and pulleys, preventing relative movement that causes wear and alignment issues. With coarse thread spacing and Class 6g thread fit, installation efficiency improves significantly while maintaining vibration resistance in high-stress applications. The external hex drive accommodates standard wrenches for reliable torque transmission in confined spaces.

Specification Summary & Compliance

This fastener maintains precision thread tolerances per Class 6g with M10x1.5 coarse thread specifications.
