Professional Applications & Engineering Value

This 2-56 UNC rounded head Phillips screw delivers exceptional engineering value in demanding industrial environments where pressure sealing and corrosion resistance are critical. The combination of 18-8 stainless steel material with passivated finish provides superior protection against chemical exposure and environmental factors, while the silicone rubber O-ring maintains reliable sealing integrity across extreme temperature fluctuations from -80° to 400°F. The fully threaded design with Class 2A thread fit ensures consistent engagement in applications requiring maximum hole diameter of 0.095", making these high-pressure screws ideal for hydraulic systems, pneumatic equipment, and industrial machinery where failure is not an option. The rounded pan head profile with Phillips drive facilitates efficient installation in confined spaces while maintaining the sealing capability under continuous 6000 psi pressure conditions.

Specification Summary & Compliance

This sealing screw features precision 2-56 UNC coarse threads with Class 2A thread fit ensuring proper engagement and reliable performance. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental compliance for industrial applications. The fully threaded design maintains consistent thread diameter of 0.086" throughout the 3/8" length, while the passivated finish on 18-8 stainless steel provides enhanced corrosion protection. The O-ring material specification uses silicone rubber rated for temperature extremes from -80° to 400°F, supporting the 6000 psi maximum pressure rating in demanding sealing applications.
