Professional Applications & Engineering Value
This black-oxide steel thumb screw delivers critical performance advantages in industrial settings where frequent adjustments are necessary. The 3/8"-16 UNC coarse thread configuration provides rapid installation while maintaining secure fastening, particularly valuable in maintenance panels, machinery guards, and equipment access points. The removable swivel tip with 10° maximum swivel angle prevents marring of sensitive surfaces, making it ideal for precision instrument mounting and electronic enclosure applications. With fully threaded construction and Rockwell C40 hardness, this fastener withstands repeated cycling without performance degradation, solving common wear issues in high-frequency adjustment scenarios while maintaining 180,000 psi tensile strength for demanding mechanical applications.
Specification Summary & Compliance
This thumb screw features precision Class 2A thread fit with UNC coarse threads (3/8"-16) in right-hand direction, ensuring consistent engagement across industrial applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental responsibility. The product maintains dimensional accuracy with 2 13/16" length, 2" head width, and 0.375" thread diameter, providing reliable performance meeting industrial fastening standards.
