Professional Applications & Engineering Value
This 6-32 UNC thumb screw is engineered to solve common industrial challenges where tool-free, quick adjustments are essential. The knurled round head and narrow profile allow for easy hand-tightening in confined spaces, reducing assembly time and minimizing the risk of cross-threading. Made from 18-8 Stainless Steel, it resists corrosion from moisture, chemicals, and outdoor exposure, making it suitable for electronics enclosures, machinery panels, and laboratory equipment. The coarse UNC threads and Class 2A thread fit provide reliable holding power in plastics, metals, and composite materials, ensuring stable performance in vibration-prone environments. Its fully threaded design and slotted drive offer versatility for both manual and tool-assisted installations, enhancing operational efficiency in maintenance and manufacturing settings.
Specification Summary & Compliance
This thumb screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy and ease of assembly. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufacturing specifications include a right-hand thread direction, coarse thread spacing, and a 3/16" head diameter with 3/8" head height, all designed to deliver reliable performance in industrial applications.
