Key Features & Benefits at a Glance
- Vibration-resistant locking through nylon patch technology prevents loosening under dynamic loads and temperature fluctuations
- Superior corrosion resistance with 18-8 stainless steel construction for long-term reliability in harsh environments
- Precision thread engagement with Class 6g fit ensures consistent clamping force and reduces assembly issues
- High-temperature performance maintains locking integrity across industrial operating ranges (-50° to 250°F)
- Optimized drive transfer through hex drive design provides maximum torque application without head interference
- Enhanced surface contact with cup tip design distributes pressure evenly while minimizing component damage
- Regulatory compliance meets RoHS 3 and REACH requirements for global manufacturing applications
Professional Applications & Engineering Value
Engineered for precision industrial assemblies where vibration resistance and thermal stability are critical, these M6 set screws solve common fastening failures in machinery, automotive, and electrical applications. The 18-8 stainless steel construction provides inherent corrosion resistance while the nylon patch locking technology creates permanent friction against backing surfaces, eliminating the need for secondary locking mechanisms. With Rockwell B80 hardness and Class 6g thread fit, these headless hex drive fasteners deliver reliable performance in confined spaces where traditional bolting solutions are impractical. The cup tip design ensures maximum surface contact while preventing damage to precision shafts and components during repeated adjustment cycles.
Specification Summary & Compliance
Manufactured to DIN 916 / ISO 4029 standards with Class 6g thread tolerance for precision fit. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. Features M6x1mm coarse thread with right-hand direction and 25mm length. The nylon patch thread locker maintains performance across specified temperature ranges while the Rockwell B80 hardness ensures durability in demanding applications.
