Professional Applications & Engineering Value
This low profile thumb screw, crafted from 18-8 Stainless Steel, is engineered to solve common industrial challenges like frequent access panel adjustments and corrosion in humid or washdown environments. The knurled head offers a non-slip surface, enabling quick hand-tightening and removal, which reduces maintenance time and eliminates the need for tools that can strip or damage fasteners. Its coarse UNC thread and Class 2A fit provide rapid installation and reliable holding power in wood, metal, and plastic assemblies. The partially threaded shank with an extended tip aids in initial alignment, preventing cross-threading and ensuring a secure fit in applications such as machinery guards, electronic enclosures, and production jigs, enhancing operational efficiency and equipment uptime.
Specification Summary & Compliance
This thumb screw features a 5/16"-18 UNC thread with a Class 2A thread fit for precise dimensional tolerance. It is manufactured from 18-8 Stainless Steel and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring it is free of hazardous substances and suitable for use in regulated industrial and commercial applications.
