- High tensile strength of 70,000 psi ensures reliable performance under demanding mechanical loads
- Precise Class 2A thread fit provides consistent engagement and reduces cross-threading risks during assembly
- Fine UNF threading offers superior holding power compared to coarse thread alternatives
- Phillips No. 2 drive compatibility with standard tools for efficient installation and removal
- Complete regulatory compliance meeting ASME B18.13 specifications and environmental standards
Professional Applications & Engineering Value
These 10-32 UNF rounded head screws with external-tooth lock washers are engineered to solve critical vibration-induced loosening in industrial equipment, machinery, and precision assemblies. The combination of 18-8 stainless steel material and passivated finish provides exceptional corrosion resistance in harsh environments while maintaining 70,000 psi tensile strength. The fully threaded design ensures maximum engagement in thin materials, while the fine thread spacing delivers superior clamping force distribution. These Phillips drive screws are particularly valuable in applications where reliable fastening under continuous vibration is essential, such as electronic enclosures, automotive components, and manufacturing equipment where maintenance access is limited.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNF fine threading (10-32) and 1/4" length. Complies with ASME B18.13 specifications for screw and washer assemblies. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The assembly features matching passivated finishes on both screw and 410 stainless steel lock washer components for consistent corrosion protection.
