Key Features & Benefits at a Glance
- Vibration-resistant locking with nylon patch thread locker maintains secure fastening even under dynamic loads
- Exceptional corrosion protection from black-oxide coating extends service life in demanding industrial environments
- High-strength alloy steel construction with Rockwell C45 hardness provides reliable performance in high-stress applications
- Precise hex drive design (0.9mm) enables easy installation and removal while preventing tool slippage
- Wide temperature tolerance (-50° to 250°F) ensures consistent performance across diverse operating conditions
- Secure cup tip design creates positive seating and prevents damage to mating surfaces
- Standardized metric threading (Class 5g6g) guarantees compatibility and interchangeability with existing components
Professional Applications & Engineering Value
This M2 set screw with black-oxide alloy steel construction addresses critical challenges in precision assembly applications where space constraints and vibration resistance are paramount. The headless design combined with hex drive installation allows for flush mounting in tight spaces while maintaining tool accessibility. The integrated nylon patch thread locker provides permanent vibration resistance without requiring secondary locking components, making it ideal for precision machinery, electronic enclosures, and automotive assemblies. The coarse thread spacing and Class 5g6g thread fit ensure rapid installation while maintaining precise alignment in metric fastening systems. The cup tip design distributes clamping force evenly, preventing surface damage to shafts and components while providing superior grip.
Specification Summary & Compliance
This metric set screw features M2 x 0.4mm coarse threading with Class 5g6g tolerance for precision fit. Manufactured to DIN 916/ISO 4029 specifications with Rockwell C45 hardness rating. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The thread locker maintains effectiveness across the specified temperature range of -50° to 250°F.
