S-95862A108 4-40 x 27/64" Set Screws

Key Features & Benefits at a Glance

• Excellent corrosion resistance with Nylon Plastic construction, ideal for environments where metal fasteners would degrade
• Secure and reliable fastening ensured by the Class 2A thread fit, providing consistent engagement and holding power
• Broad temperature tolerance from -40° to 185° F, maintaining performance in varied operational conditions
• Minimal component interference due to the headless and flat tip design, perfect for flush-mount applications
• Easy installation and adjustment with the slotted drive, allowing for straightforward use with standard tools
• Lightweight and non-conductive properties reduce overall assembly weight and prevent electrical conductivity issues
• Environmentally responsible manufacturing with full RoHS 3 compliance, meeting stringent international regulations

Professional Applications & Engineering Value

This 4-40 UNC coarse thread Nylon Plastic set screw is engineered to address common challenges in precision assemblies where metal fasteners are unsuitable. Its headless design with a flat tip provides a flush finish, preventing protrusion in tight spaces and reducing the risk of snagging or interference in moving parts. The right-hand thread and coarse pitch ensure quick installation and strong holding force in plastic or soft materials, commonly used in electronics, automotive trim, and consumer goods. The off-white color offers a clean, neutral appearance for aesthetic-sensitive applications. With a operational range from -40° to 185° F, it performs reliably in both cold and moderately high-temperature environments, making it a versatile choice for set screws in industries requiring durable, non-metallic fastening solutions that resist rust and electrical currents.

Specification Summary & Compliance

This set screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. It measures 4-40 thread size, 0.112" thread diameter, and 27/64" length in the inch system. Manufactured from Nylon Plastic with a flat tip and slotted drive, it complies with RoHS 3 (2015/863/EU) regulations, ensuring it is free from hazardous substances and suitable for global markets requiring environmental and safety standards.
