Professional Applications & Engineering Value
This 18-8 stainless steel thumb screw is engineered to address common industrial challenges such as misalignment and corrosion in precision assemblies. The 3/16" shoulder offers exact positioning for components in machinery, electronic enclosures, and optical devices, minimizing vibration-induced loosening. Its UNC coarse threads and Class 2A fit ensure quick, secure fastening, while the knurled head combined with a hex drive allows for both manual and tool-assisted tightening. Ideal for maintenance-heavy environments, this screw's high tensile strength and corrosion-resistant properties reduce downtime and extend service life in industrial thumb screw applications, from manufacturing equipment to automotive systems.
Specification Summary & Compliance
This thumb screw adheres to UNC thread standards with an 8-32 size and Class 2A thread fit for consistent dimensional accuracy. The shoulder features precise tolerances (diameter: -0.001" to 0", length: 0" to 0.002") to ensure reliable performance. Manufactured from 18-8 stainless steel, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally responsible sourcing and use in global markets.
