S-91390A658 M10 x 35 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with hardened alloy steel construction and cup point tip that bites into mating surfaces for permanent, vibration-resistant fastening
• Precise thread engagement with Class 5g6g fine thread fit ensuring consistent torque transmission and reduced risk of cross-threading in critical assemblies
• Exceptional durability with Rockwell C45 hardness rating providing excellent resistance to wear and deformation under heavy loads
• Streamlined installation featuring headless design and 5mm hex drive for flush mounting in confined spaces with standard tools
• Reliable performance manufactured to DIN 916/ISO 4029 standards for dimensional accuracy and interchangeability in metric applications
• Environmental compliance meeting RoHS 3 and REACH regulations for safe use in regulated industries and international markets
• Optimized for fine adjustments with 1.25mm pitch right-hand threads delivering finer positioning control than coarse thread alternatives

Professional Applications & Engineering Value

This M10 set screw delivers critical engineering value in applications requiring permanent shaft-hub connections and precise component positioning. The alloy steel construction, hardened to Rockwell C45, provides the necessary strength to prevent loosening under vibration and rotational forces in machinery, automotive, and power transmission systems. The cup point design creates concentrated pressure points that dig into shafts and collars, eliminating slippage in high-torque environments. With fine thread spacing (1.25mm pitch) and Class 5g6g thread fit, this metric set screw offers superior adjustment precision compared to coarse-thread alternatives, making it ideal for positioning applications where minute adjustments matter. The headless configuration with 5mm hex drive enables flush installation in space-constrained assemblies while maintaining full engagement strength.

Specification Summary & Compliance

This M10 x 1.25mm x 35mm set screw features Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional tolerances for reliable performance. Manufactured in compliance with DIN 916 and ISO 4029 specifications for dimensional accuracy and mechanical properties. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements, making it suitable for regulated industrial applications worldwide.
