S-93245A439 M8 x 70 mm DIN 913, ISO 4026 Set Screws

Key Features & Benefits at a Glance

• Superior holding power from high-strength alloy steel construction, ensuring reliable fastening in demanding applications.
• Excellent wear resistance and durability due to Rockwell C45 hardness, extending service life and reducing replacement frequency.
• Precise and secure thread engagement with Class 5g6g thread fit, minimizing the risk of loosening under vibration or load.
• Efficient installation and removal using the 4mm hex drive, providing a flush, headless finish ideal for confined spaces.
• Optimized for coarse thread applications with M8 x 1.25mm right-hand threads, offering quick assembly and strong clamping force.
• Flush mounting capability with a flat tip design, preventing surface damage and ensuring a clean, professional appearance.
• Guaranteed quality and safety through compliance with DIN 913/ISO 4026, RoHS 3, and REACH, meeting strict industrial and environmental standards.

Professional Applications & Engineering Value

This M8 set screw is engineered to address critical challenges in industrial assembly, such as component slippage and fastener failure under stress. Manufactured from alloy steel and hardened to Rockwell C45, it provides exceptional shear and tensile strength, making it ideal for securing pulleys, gears, and collars on shafts in machinery and automotive systems. The coarse thread (1.25mm pitch) and Class 5g6g thread fit ensure rapid installation and a tight grip, even in high-vibration environments. Its headless, hex drive design allows for seamless integration where protruding fasteners are not feasible, while the flat tip distributes pressure evenly to prevent damage to secured components. Fully compliant with DIN 913 and ISO 4026 standards, this screw delivers consistent performance in precision engineering applications, from conveyor systems to motor assemblies.
