S-92905A687 M20 x 30 mm DIN 915, ISO 4028 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with coarse 2.5mm pitch threads for secure fastening in demanding applications
• Superior material strength from alloy steel with Rockwell C45 hardness for reliable performance under high stress
• Precision thread fit with Class 6g tolerance ensuring consistent engagement and vibration resistance
• Enhanced grip capability through extended tip design (15mm diameter) for deeper penetration and reduced slippage
• Space-saving headless construction allowing flush mounting where protruding fasteners are impractical
• Easy installation and removal with standard 10mm hex drive compatible with common industrial tools
• Long-term reliability with right-hand thread direction following industry-standard assembly practices

Professional Applications & Engineering Value

This M20 set screw delivers critical engineering solutions for industrial applications requiring precise component positioning and permanent fastening. The alloy steel construction with Rockwell C45 hardness provides exceptional resistance to shear forces and vibrational loosening in heavy machinery, automotive assemblies, and manufacturing equipment. The extended tip design (10.36mm length, 15mm diameter) creates superior bite into mating components, preventing rotational movement in pulley systems, gear assemblies, and shaft collars. With coarse metric threads and Class 6g thread fit, this headless set screw ensures rapid installation while maintaining precise alignment in high-vibration environments where fine threads might fail. The hex drive configuration allows for high torque application without stripping, making it ideal for maintenance-critical applications requiring periodic adjustment or replacement.

Specification Summary & Compliance

This precision fastener features M20x2.5mm coarse threads with Class 6g thread fit per ISO metric standards, ensuring dimensional accuracy for reliable performance. Manufacturing complies with DIN 915 and ISO 4028 specifications for set screws with extended points. Tip dimensions maintain tight tolerances (length: -0.36mm to 0, diameter: -0.43mm to 0) for consistent application performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications with strict material restrictions.
