• Reliable vibration resistance through the nylon patch thread locker, maintaining secure fastening across a wide temperature range from -40° to 225° F.
• High tensile strength of 70,000 psi for robust load-bearing capability, reducing the risk of mechanical failure in demanding applications.
• Precise Class 2A thread fit with UNF fine threading, enabling smooth installation and consistent engagement for improved assembly efficiency.
• Broad temperature compatibility with O-ring performance from -80° to 400° F, ideal for extreme thermal cycling without compromising seal integrity.
• Compliance with MIL-DTL-18240 and environmental standards including RoHS and REACH, ensuring quality and regulatory adherence for industrial use.

Professional Applications & Engineering Value

This 0-80 UNF rounded head screw is engineered to address critical sealing and vibration challenges in industrial settings. The combination of a silicone rubber O-ring and nylon patch thread locker creates a dual-sealing mechanism that effectively prevents fluid ingress and fastener loosening under pressures up to 6000 psi. Made from 18-8 stainless steel with a passivated finish, it resists corrosion in moist or chemical environments, while the Phillips drive and Class 2A thread fit ensure easy, precise installation. Ideal for high-pressure sealing applications in aerospace, automotive, and hydraulic systems, this screw maintains reliability across extreme temperatures from -40° to 400° F, reducing maintenance needs and enhancing operational safety.

Specification Summary & Compliance
