Professional Applications & Engineering Value
This black-oxide steel thumb screw is engineered to address common industrial challenges such as frequent adjustments and component wear. The low-profile round head with knurled texture allows for easy hand-tightening in tight spaces, reducing tool dependency and speeding up maintenance. The removable swivel tip with a 10° maximum angle accommodates misalignment and protects sensitive surfaces from scratches, making it ideal for electronic enclosures, machinery panels, and fixture clamping. Constructed from robust steel with UNC coarse threading, it ensures reliable performance in vibration-prone applications, while the fully threaded design provides consistent clamping force. This combination of features minimizes downtime and enhances operational efficiency in B2B settings.
Specification Summary & Compliance
This thumb screw adheres to Class 2A thread fit and UNC coarse thread standards for precise dimensional accuracy. It is manufactured with a right-hand thread direction and complies with RoHS 3 (2015/863/EU) regulations under exemption 6(a)-I for lead as an alloying element in steel, ensuring environmental and safety standards are met for industrial use.
