S-91390A618 M10 x 80 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding strength with Rockwell C45 hardness alloy steel, ensuring long-term reliability in demanding applications.
• Secure fastening and alignment thanks to the cup point tip design, which bites into surfaces to prevent loosening under vibration.
• Easy installation and removal with a 5 mm hex drive, allowing for efficient assembly in confined spaces without a protruding head.
• Consistent thread performance with Class 5g6g thread fit and coarse thread spacing, providing reliable engagement and resistance to cross-threading.
• Broad industrial compatibility due to compliance with DIN 916 / ISO 4029 standards, ensuring interchangeability and quality assurance.
• Environmental and safety compliance with RoHS 3 and REACH regulations, making it suitable for global supply chains and sensitive applications.
• Optimized for high-stress environments with a right-hand metric thread (M10x1.5mm) and 80mm length, offering robust fastening in machinery and equipment.

Professional Applications & Engineering Value

This M10 set screw is engineered to address common industrial challenges such as component slippage and misalignment in high-vibration settings. Made from alloy steel with a Rockwell C45 hardness, it resists wear and deformation, while the headless hex drive and cup point tip provide concentrated clamping force to secure parts like gears, pulleys, and shafts without protruding hardware. The coarse thread spacing and Class 5g6g thread fit ensure quick installation and reliable performance in metric-based assemblies, reducing maintenance downtime. Ideal for automotive, manufacturing, and heavy machinery, this screw delivers precision and durability where industrial set screws are critical for operational safety and efficiency.
