- High tensile strength of 70,000 psi provides dependable load-bearing capacity for critical mechanical assemblies.
- Effortless installation with Phillips No. 2 drive and standard pan head design, reducing assembly time and tool wear.
- Precise thread engagement with UNC coarse threads and Class 2A fit, ensuring consistent fastening in various materials.
- Full threading along the 1" length offers maximum grip and adjustment flexibility in deep or variable thickness applications.
- Regulatory compliance with ASME B18.13, RoHS 3, and REACH standards, guaranteeing safety and environmental responsibility.
Professional Applications & Engineering Value
Engineered for demanding industrial environments, these rounded head Phillips screws integrate a lock washer to solve common vibration-induced loosening in machinery, automotive, and electrical enclosures. The 18-8 stainless steel material, enhanced by a passivated finish, resists oxidation and chemical exposure, extending service life in humid or corrosive settings. With UNC coarse threads and a Class 2A thread fit, they ensure rapid, secure installation in metals and plastics, reducing assembly errors. The combination of 70,000 psi tensile strength and full threading provides robust clamping force, making them ideal for high-stress applications where fastener integrity is critical to operational safety and reduced maintenance.
Specification Summary & Compliance
This fastener meets ASME B18.13 specifications for dimensional accuracy, with UNC 8-32 coarse threads and Class 2A thread fit ensuring precise tolerances. The fully threaded 1" length and integrated internal-tooth lock washer (0.338" OD, 0.023" thickness) enhance performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms adherence to environmental and safety regulations, supporting sustainable procurement.
