- Superior sealing performance with a silicone O-ring that maintains integrity across extreme temperatures from -150°F to 500°F, preventing leaks in demanding environments.
- Exceptional corrosion resistance provided by 18-8 stainless steel construction and a passivated finish, ensuring long-term durability in harsh or humid conditions.
- High mechanical strength with a tensile strength of 70,000 psi, offering reliable fastening under heavy loads and vibration.
- Pressure-tight sealing capability that withstands up to 20,000 psi, ideal for high-pressure fluid or gas systems.
- Precise and easy installation thanks to the Class 2A thread fit and Phillips No. 2 drive, reducing assembly time and improving consistency.
- Full threading design ensures maximum grip and uniform stress distribution along the entire length for secure, lasting holds.
- Compliance with environmental standards including RoHS 3 and REACH, making it safe for regulated industrial and commercial applications.
Professional Applications & Engineering Value
This 8-32 UNC flat head screw is engineered to address critical sealing and corrosion challenges in industrial settings. The combination of 18-8 stainless steel and a passivated finish provides excellent resistance to rust and chemicals, while the silicone O-ring creates a reliable seal against moisture, dust, and pressure variations. Its coarse UNC threads and Class 2A fit ensure quick, accurate installation with standard tools, reducing the risk of cross-threading. Ideal for applications in pumps, valves, machinery enclosures, and automotive assemblies, this fastener delivers consistent performance in high-temperature or high-pressure environments, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This screw features a 3/4" length with UNC coarse threads and Class 2A thread fit for precise dimensional accuracy. It is manufactured from 18-8 stainless steel with a passivated finish and includes a silicone O-ring rated for -150°F to 500°F. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
