Key Features & Benefits at a Glance
- Corrosion-resistant performance with 18-8 stainless steel construction for long-term reliability in demanding environments
- Secure, flush mounting thanks to the headless design that sits perfectly flush with or below the component surface
- High-torque installation capability enabled by the 1.5mm hex drive, preventing tool slippage and damage
- Quick assembly and reliable holding with the M3 coarse (0.5mm pitch) thread ensuring faster installation and vibration resistance
- Pressure equalization and debris clearance through the integrated 1.1mm vent, preventing air or fluid lock and maintaining function
- Precise thread engagement with Class 6g tolerance for consistent fit and reduced risk of cross-threading in mating components
- Cup point design that bites into shafts for superior resistance to rotation and axial movement
Professional Applications & Engineering Value
This M3 metric set screw is engineered to address critical challenges in precision assembly and motion control systems. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for applications exposed to moisture, chemicals, or outdoor conditions. The headless and vented design allows for unobstructed rotational movement while preventing pressure buildup in pneumatic or hydraulic systems. With its Class 6g thread fit and coarse pitch, this screw ensures rapid installation and maintains secure positioning in pulleys, gears, and collars—effectively resisting loosening under vibration. The 1.5mm hex drive offers reliable torque transmission, reducing the risk of stripping during high-stress industrial use.
Specification Summary & Compliance
This precision set screw adheres to metric thread standards with M3 x 0.5mm coarse pitch and Class 6g thread tolerance for consistent dimensional accuracy. It features a cup point tip, right-hand thread direction, and a 1.1mm vent diameter. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial components.
