S-91390A584 M30 x 50 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with M30 coarse 3.5mm pitch threads for reliable fastening in high-vibration environments.
• Exceptional durability from alloy steel construction and Rockwell C45 hardness, resisting wear and deformation under heavy loads.
• Precise thread fit with Class 5g6g tolerance ensuring consistent engagement and reduced risk of cross-threading.
• Secure installation via 14mm hex drive, providing high torque transmission and preventing tool slippage.
• Effective grip and alignment with cup point tip that bites into materials, minimizing component movement.
• Space-saving headless design allowing flush mounting in applications where protruding fasteners are not feasible.
• Global compliance assurance meeting DIN 916/ISO 4029 standards, RoHS 3, and REACH for safe, regulated use.

Professional Applications & Engineering Value

This M30 set screw is engineered to address critical challenges in industrial assembly, where vibration resistance and long-term reliability are paramount. The alloy steel material, combined with Rockwell C45 hardness, ensures the fastener maintains its integrity under repetitive stress and heavy loads, preventing loosening in machinery, automotive components, and structural frameworks. The cup point tip provides excellent bite into shafts and hubs, securing parts without the need for additional locking mechanisms. Its headless design and metric coarse thread make it ideal for confined spaces and high-torque applications, reducing maintenance intervals and enhancing operational safety. Compliant with DIN 916 and ISO 4029, this screw delivers consistent performance in global engineering projects.
