Professional Applications & Engineering Value
This 4-40 UNC nylon plastic set screw delivers exceptional value in applications where metal fasteners would cause problems. The off-white nylon material provides inherent corrosion resistance, eliminating galvanic corrosion issues when used with dissimilar metals and making it ideal for electronic enclosures, marine components, and chemical processing equipment. The coarse UNC thread design ensures quick installation and reliable holding power in plastic and soft material applications. With its headless configuration and 3/64" hex drive, this fastener solves space-constrained assembly challenges while maintaining a clean, flush appearance. The temperature resistance from -40° to 185°F makes it suitable for outdoor equipment, automotive components, and industrial machinery experiencing thermal cycling.
Specification Summary & Compliance
This set screw features 4-40 UNC coarse threads with Class 2A thread fit for consistent dimensional accuracy and proper engagement. The fastener measures 1/2" in length with 0.112" thread diameter and flat tip design for secure positioning. Manufactured from durable nylon plastic in off-white color, the screw is fully RoHS 3 (2015/863/EU) compliant for environmental safety and regulatory requirements in industrial applications.
