Professional Applications & Engineering Value
This 2-56 UNC rounded pan head machine screw in 316 stainless steel addresses critical challenges in industrial settings where corrosion and mechanical stress are prevalent. The passivated finish significantly enhances resistance to chlorides and acidic conditions, making it suitable for chemical processing equipment, marine hardware, and food-grade machinery. Its coarse thread spacing and Class 2A fit facilitate quick installation in soft metals or plastics while maintaining vibration resistance. With a Rockwell B85 hardness and fully threaded design, it distributes clamping forces evenly, preventing joint failure in high-vibration environments like assembly lines or outdoor structures. Engineers value this screw for maintaining 80,000 psi tensile strength under dynamic loads, ensuring long-term reliability in industrial fastening applications.
Specification Summary & Compliance
This screw maintains precise Class 2A thread fit per UNC standards, with a diameter of 0.086" and coarse spacing for optimal engagement. Manufacturing follows ASME B18.6.3 specifications for dimensional consistency. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The passivated finish meets industry corrosion protection standards without compromising thread integrity.
