Key Features & Benefits at a Glance
- Permanent vibration-resistant locking with nylon patch thread locker that maintains secure fastening in demanding environments
- Superior corrosion resistance provided by 18-8 stainless steel construction for extended service life in harsh conditions
- Precise torque transmission through 2.5mm hex socket drive for reliable installation without stripping
- Enhanced grip and positioning with cup point design that bites into mating surfaces for superior resistance to rotation
- Wide temperature compatibility from -50° to 250°F (-45° to 121°C) for diverse industrial applications
- Consistent thread engagement with Class 6g tolerance ensuring reliable performance in metric assemblies
- Space-saving headless design ideal for applications where protruding fastener heads are not feasible
Professional Applications & Engineering Value
This M5 set screw with nylon patch thread locking addresses critical challenges in precision assembly operations where vibration-induced loosening compromises equipment reliability. The 18-8 stainless steel construction provides essential corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements, while the cup point design creates permanent dimples in shaft surfaces to prevent rotational slippage under torque loads. Engineered to DIN 916/ISO 4029 standards, this hex socket set screw delivers consistent performance in positioning components on shafts, securing pulleys and gears, and maintaining alignment in industrial equipment, automotive systems, and precision instruments. The 2.5mm hex drive facilitates precise installation in confined spaces where conventional fasteners cannot be accommodated.
Specification Summary & Compliance
This metric set screw features M5x0.8mm coarse threads with Class 6g tolerance for precise fitment, manufactured from 18-8 stainless steel with Rockwell B80 hardness. The fastener complies with DIN 916/ISO 4029 manufacturing specifications and includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications with strict material restrictions.
