Professional Applications & Engineering Value
These 8-32 UNC coarse thread screws with internal-tooth lock washers deliver critical vibration resistance in industrial machinery, electrical enclosures, and automotive assemblies where loosening under dynamic loads poses significant reliability concerns. The 18-8 stainless steel construction combined with passivated finish provides exceptional corrosion protection, making these rounded head screws ideal for applications exposed to moisture, chemicals, or outdoor elements. The fully threaded design ensures maximum engagement in thin materials, while the Phillips No. 2 drive facilitates efficient installation in production environments. These locking fasteners effectively replace traditional screw-and-washer combinations, streamlining inventory while maintaining 70,000 psi tensile strength for demanding mechanical fastening requirements.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse thread specifications. These rounded head screws comply with ASME B18.13 manufacturing standards and feature full regulatory compliance including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements. The complete assembly includes 410 stainless steel internal-tooth lock washers with matching passivated finish for consistent corrosion protection throughout the fastener system.
