Professional Applications & Engineering Value

This nylon plastic thumb screw solves critical assembly challenges where metal fasteners are unsuitable. The knurled head enables rapid installation without tools, reducing assembly time in electronics, machinery panels, and consumer products. Its non-conductive and chemical-resistant properties prevent short circuits and degradation in humid or corrosive environments. The 6-32 UNC coarse thread with Class 2A fit ensures reliable engagement in plastic or metal housings, while the raised round head profile with collar provides stable seating. Ideal for applications requiring frequent adjustments, such as access panels, calibration devices, and thermal management systems, this screw combines durability with operational efficiency.

Specification Summary & Compliance

Manufactured to precise inch system dimensions, this thumb screw features a 6-32 UNC coarse thread with Class 2A thread fit for consistent performance. The fully threaded 3/8" length and right-hand thread direction adhere to standard assembly practices. It is fully RoHS 3 (2015/863/EU) Compliant, meeting stringent environmental regulations for hazardous substance restrictions. No specific hardness rating is provided, making it suitable for applications where marring or scratching of surfaces must be avoided.
