Professional Applications & Engineering Value
This 18-8 stainless steel thumb screw is engineered to solve common industrial challenges where tool-less, repeated access is required. The knurled head provides a non-slip surface, enabling secure hand-tightening and loosening in high-vibration environments, from electronic enclosures to machinery panels. Its coarse UNC thread and Class 2A fit ensure rapid alignment and engagement, reducing assembly time while the fully threaded design offers consistent clamping force along the entire length. The combination of high tensile strength and corrosion resistance makes it a dependable choice for industrial maintenance, OEM equipment, and applications demanding both durability and regulatory compliance like RoHS and REACH.
Specification Summary & Compliance
This thumb screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. It is manufactured from 18-8 stainless steel with a Rockwell B85 hardness and 80,000 psi tensile strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
