Professional Applications & Engineering Value
This glass-filled nylon thumb screw addresses common industrial challenges such as frequent adjustments and exposure to harsh conditions. The knurled head provides excellent manual grip without tools, speeding up assembly in electronics, machinery, and enclosures. With a UNC coarse thread and Class 2A fit, it ensures quick, secure installation and reduces assembly errors. The material's inherent resistance to chemicals and temperature fluctuations from -40° to 185° F makes it suitable for outdoor, automotive, and electrical applications where metal fasteners may corrode or conduct electricity. Its RoHS 3 and REACH compliance further supports use in regulated industries, offering a durable, non-conductive alternative that maintains performance under stress.
Specification Summary & Compliance
This thumb screw adheres to UNC 1/4"-20 coarse thread specifications with a Class 2A thread fit for consistent dimensional accuracy. It is fully threaded and right-hand oriented, manufactured from glass-filled nylon plastic with a tensile strength of 18,000 psi. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety standards for industrial use.
