Professional Applications & Engineering Value

This black-oxide steel thumb screw delivers exceptional performance in industrial settings where frequent adjustments and reliable fastening are critical. The knurled head texture provides superior manual grip even with oily hands or when wearing gloves, eliminating the need for tools in applications requiring regular maintenance access. The 10-32 UNF fine thread configuration ensures precise engagement in machinery, electronic enclosures, and equipment panels, while the partially threaded design with extended tip facilitates quick alignment and prevents cross-threading damage. The corrosion-resistant black-oxide finish protects against environmental factors in manufacturing facilities, laboratories, and outdoor applications, making these industrial thumb screws ideal for repeated use in demanding conditions.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent performance across applications. The 10-32 UNF thread specification ensures compatibility with standard components, while the partially threaded design (1-1/4" thread length on 1-1/2" overall length) provides optimal fastening characteristics. This product is fully RoHS 3 (2015/863/EU) compliant with exemption 6(a)-I for lead as an alloying element in steel, meeting international environmental regulations for industrial components.
