Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 316 stainless steel construction and passivated finish, ideal for harsh chemical and marine environments
- Superior thread precision with Class 3A fit and 10-32 UNF fine threading for reliable, vibration-resistant fastening in critical assemblies
- High mechanical strength delivering 70,000 psi tensile strength and Rockwell B55 hardness for heavy-duty industrial applications
- Streamlined installation via 1/8" hex drive and rounded button head design, enabling efficient torque application in confined spaces
- Full threading coverage along the 7/16" length ensures maximum grip and load distribution across joined components
- Regulatory compliance with ASME B18.3 manufacturing standards, RoHS 3, and REACH for global industrial supply chain integration
- Right-hand thread orientation provides standardized installation compatibility with common assembly tools and procedures
Professional Applications & Engineering Value
Engineered for demanding environments, these 316 stainless steel rounded head screws combine molybdenum-enhanced alloy composition with passivated surface treatment to combat chloride-induced stress corrosion cracking—a critical failure mode in chemical processing, marine hardware, and offshore equipment. The UNF fine thread profile with Class 3A tolerance maintains clamping force under high-vibration conditions, preventing loosening in machinery, precision instruments, and automotive subsystems. The low-profile button head with hex drive accommodates limited clearance applications while providing sufficient torque transmission for assemblies requiring 70,000 psi tensile strength.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit ensuring precise engagement. The 10-32 UNF fine thread maintains consistent pitch accuracy while the fully threaded 7/16" length provides complete fastening coverage. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for hazardous substance restrictions. Material certifications validate 316 stainless steel composition with Rockwell B55 hardness and mechanical properties exceeding industrial fastening requirements.
