S-91390A176 M12 x 30 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with high-strength alloy steel construction and Rockwell C45 hardness for reliable performance in demanding applications
• Precise thread engagement with Class 5g6g thread fit ensuring consistent fastening and vibration resistance
• Easy installation and removal using standard 6mm hex tools without requiring additional head space
• Optimized for coarse thread applications with M12x1.75mm thread configuration for faster assembly and reduced cross-threading risk
• Secure positioning capability with cup tip design that provides positive contact and prevents component slippage
• International compliance assurance meeting both DIN 916 and ISO 4029 standards for global project compatibility
• Environmentally responsible manufacturing with full RoHS 3 and REACH compliance for sustainable sourcing

Professional Applications & Engineering Value

This M12 set screw delivers exceptional engineering value in industrial applications where space constraints and vibration resistance are critical concerns. The headless design allows for flush mounting in tight spaces while the alloy steel construction with Rockwell C45 hardness provides superior resistance to wear and deformation under heavy loads. The coarse thread pitch (1.75mm) ensures rapid installation and reliable performance in materials where fine threads might strip or fail. Commonly specified in machinery assembly, automotive components, and precision equipment, this metric set screw with its cup tip creates positive mechanical stops that prevent axial movement of gears, pulleys, and bearings. The hex drive configuration permits high torque application without slippage, making it ideal for maintenance-critical applications where repeated adjustments may be necessary.

Specification Summary & Compliance

This set screw features precise Class 5g6g thread fit according to ISO metric standards, ensuring dimensional accuracy and proper engagement. Manufacturing complies with DIN 916 and ISO 4029 specifications for consistent quality and performance. The product meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations, demonstrating environmental responsibility while maintaining the mechanical properties required for industrial fastening applications.
