S-91385A408 M3 x 10 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Vibration-resistant secure locking with the integrated Nylon Patch thread locker, preventing loosening under dynamic loads
• Enhanced durability and corrosion resistance from the Black-Oxide finish on high-strength alloy steel
• Reliable thread engagement and precision fit ensured by Class 5g6g thread tolerance for consistent assembly
• High torque application capability with the 1.5 mm Hex Drive and Rockwell C45 hardness for repeated use without stripping
• Secure fastening in blind holes due to the Cup Tip design that provides excellent bite and resistance to rotation
• Broad operational temperature range from -50° to 250° F, maintaining locking performance in varied environments
• Global standard compliance with DIN 916/ISO 4029, ensuring interchangeability and reliability in international projects

Professional Applications & Engineering Value

This M3 x 0.5 mm set screw is engineered to address common industrial challenges such as component slippage and vibration-induced failure in precision assemblies. The Black-Oxide alloy steel construction provides superior strength and moderate corrosion resistance, ideal for machinery, automotive, and electronics where space is constrained and a headless design is required. The Nylon Patch locking element effectively secures the coarse Metric thread against loosening, reducing maintenance needs in dynamic applications. Its cup tip ensures positive contact on shafts or in blind holes, making it a reliable choice for permanent or semi-permanent fastening in demanding environments.
