Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments
- Exceptional mechanical strength delivering 70,000 psi tensile strength and Rockwell B55 hardness for reliable, long-term performance
- Precise Class 3A thread fit ensures secure fastening with reduced risk of cross-threading in demanding applications
- Efficient hex drive design (7/32") provides high torque transmission and prevents stripping during installation
- Optimized 82° countersink angle creates flush surface finishes while maintaining structural integrity
- Full threading along 1-1/8" length enables maximum grip and adjustment flexibility in assembled components
- Comprehensive compliance with ASME B18.3 standards and environmental regulations (RoHS 3, REACH) for quality assurance
Professional Applications & Engineering Value
These 3/8"-16 UNC flat head screws deliver critical engineering solutions where flush mounting and corrosion resistance are paramount. The 18-8 stainless steel composition combined with passivated finish provides exceptional protection against chemical exposure and atmospheric corrosion, making them ideal for industrial equipment, marine applications, and food processing machinery. The coarse UNC threads and Class 3A fit ensure rapid installation with minimal cross-threading risk, while the hex drive design accommodates high torque requirements in confined spaces. These fully threaded screws maintain consistent 70,000 psi tensile strength throughout their length, providing reliable clamping force in vibration-prone environments where fastener integrity is critical to operational safety.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit and UNC coarse threading (3/8"-16). Complies with ASME B18.3 specifications where applicable per ASTM F879. Meets environmental compliance standards including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. Features standard 82° countersink angle and complete threading along the 1-1/8" length for consistent performance across industrial applications.
