Key Features & Benefits at a Glance
- Non-conductive and corrosion-resistant nylon plastic construction ensures reliable performance in electrical applications and harsh environments.
- Secure and flush mounting with a headless, flat tip design that sits perfectly within components without protruding.
- Easy installation and high torque resistance provided by the 3/64" hex drive, minimizing the risk of stripping during assembly.
- Wide operational temperature range from -40° to 185° F, making it suitable for diverse industrial and outdoor settings.
- Precise and reliable coarse threading with UNC 4-40 size and Class 2A fit for consistent engagement and vibration resistance.
- Environmentally compliant with RoHS 3 standards, ensuring safety and regulatory adherence for global supply chains.
- Cost-effective and lightweight plastic design reduces overall component weight and is ideal for non-structural fastening needs.
Professional Applications & Engineering Value
This 4-40 UNC nylon plastic set screw is engineered to address common industrial challenges such as galvanic corrosion, electrical insulation, and weight reduction. Its headless design with a flat tip ensures a seamless fit in assemblies, preventing interference and maintaining a clean profile. The right-hand coarse thread and Class 2A thread fit provide excellent holding power in plastics and soft materials, reducing the risk of cross-threading. Ideal for electronics, automotive controls, and consumer goods, this screw offers a non-magnetic, corrosion-resistant alternative to metal fasteners, enhancing durability in moist or chemically exposed environments while complying with RoHS 3 regulations for safer product integration.
Specification Summary & Compliance
This set screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. It meets RoHS 3 (2015/863/EU) compliance, ensuring it is free from hazardous substances. The specifications include a 4-40 thread size, 11/16" length, and 3/64" hex drive, manufactured to provide reliable performance in specified temperature ranges without hardness ratings, suitable for general-purpose industrial use.
