Key Features & Benefits at a Glance
- Superior sealing performance with Buna-N rubber O-rings rated for pressures up to 1500 psi, preventing leaks in demanding applications.
- Excellent corrosion resistance due to 18-8 stainless steel construction and passivated finish, ensuring longevity in harsh environments.
- High tensile strength of 70,000 psi provides reliable fastening under mechanical stress, reducing failure risks.
- Precise Class 2A thread fit with UNF fine threading for smooth installation and secure, vibration-resistant connections.
- Undercut flat head design allows for flush mounting, minimizing protrusion and improving aesthetic or functional clearance.
- Wide temperature tolerance from -40° to 225°F, maintaining seal integrity across diverse operating conditions.
- Compliance with RoHS 3 and REACH ensures environmental and safety standards are met for global industrial use.
Professional Applications & Engineering Value
This 10-32 UNF flat head Phillips screw is engineered to address critical sealing challenges in industrial assemblies, such as fluid systems, machinery enclosures, and automotive components. The combination of 18-8 stainless steel and a passivated finish offers robust corrosion resistance, while the integrated Buna-N rubber O-ring creates a reliable seal against high-pressure fluids and gases. The undercut flat head and Phillips drive facilitate easy, countersunk installation, reducing assembly time and preventing head stripping. Ideal for applications requiring fine thread precision and consistent performance, this screw minimizes maintenance needs and enhances system durability in environments exposed to moisture, chemicals, or temperature fluctuations.
Specification Summary & Compliance
The screw features a 10-32 UNF thread with Class 2A fit for precise dimensional accuracy, ensuring compatibility with standard nuts and tapped holes. It is fully threaded for maximum grip and adheres to common inch-system standards. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of restricted substances and supporting sustainable manufacturing practices.
