Professional Applications & Engineering Value

This 10-32 UNF hex head screw with integrated silicone rubber O-ring addresses critical sealing challenges in industrial applications where pressure integrity and environmental resistance are paramount. The 18-8 stainless steel construction provides superior corrosion resistance for equipment exposed to moisture, chemicals, and outdoor elements, while the fine UNF thread with Class 2A fit ensures precise engagement in tapped holes. Engineered for hydraulic systems, pneumatic controls, and fluid handling equipment, this sealing screw eliminates leakage points and maintains system integrity under high-pressure conditions up to 20,000 psi. The combination of Rockwell B85 hardness and 80,000 psi tensile strength guarantees reliable performance in vibration-prone environments where fastener failure is not an option.

Specification Summary & Compliance

This hex head screw features a 10-32 UNF fine thread with Class 2A thread fit precision, manufactured to exacting dimensional standards with a 1/2" length and fully threaded design. The product maintains compliance with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, ensuring environmental responsibility and safety in industrial applications. The silicone rubber O-ring meets the specified temperature range of -80° to 400°F, while the mechanical properties including Rockwell B85 hardness and 80,000 psi tensile strength confirm consistent performance across demanding operating conditions.
