Professional Applications & Engineering Value

This 6-32 UNC rounded head Phillips screw is engineered to address critical sealing challenges in industrial equipment, automotive components, and fluid handling systems. The combination of 18-8 stainless steel and a passivated finish resists oxidation and chemical exposure, prolonging service life in corrosive settings. The Buna-N rubber O-ring maintains elasticity across a broad temperature range, creating a tight seal that prevents leaks under pressures up to 6000 psi. Its coarse thread and Class 2A fit enable rapid assembly with high vibration resistance, reducing maintenance needs and downtime in machinery, enclosures, and pressurized devices.

Specification Summary & Compliance

This screw features a 6-32 UNC coarse thread with Class 2A tolerance for precise fit, a pan-style rounded head, and full threading. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and safe for industrial use. The O-ring is rated for temperatures from -40°F to 225°F, and the assembly supports a maximum hole diameter of 0.15".
