Professional Applications & Engineering Value

These Nylon Plastic thumb screws deliver exceptional value in applications requiring frequent access or adjustments, such as electronic enclosures, panel fastening, and machinery guards. The non-conductive and non-magnetic properties of the material prevent electrical interference and make them ideal for sensitive equipment. The UNC coarse threading and Class 2A thread fit provide quick assembly with reduced cross-threading risk, while the fully threaded design ensures consistent clamping force along the entire length. The knurled head texture offers superior manual grip even with gloves, speeding up maintenance cycles without specialized tools. Their lightweight construction reduces overall assembly weight without compromising on the 11,000 psi tensile strength, making them a reliable choice for industrial and OEM applications.

Specification Summary & Compliance

This product features a 6-32 UNC thread size with Class 2A thread fit and coarse thread spacing, ensuring dimensional accuracy and reliable performance. The 1/2" length and 0.138" thread diameter provide standardized compatibility. Manufacturing adheres to industry standards for plastic fasteners and is fully RoHS 3 (2015/863/EU) Compliant, confirming the absence of hazardous substances for safe use in regulated environments.
