Professional Applications & Engineering Value
This 8-32 UNC thumb screw combines the corrosion-resistant properties of 18-8 Stainless Steel with the ergonomic advantages of an Acetal Plastic knurled head, creating an ideal solution for frequent-adjustment applications requiring manual operation. The low-profile round head design reduces snag hazards while the coarse thread spacing enables rapid installation and removal cycles. Engineering teams specify these thumb screws for equipment panels, access covers, and calibration mechanisms where tool-less access is essential. The fully threaded construction provides consistent clamping force along the entire 7/8" length, while the Class 3A thread fit ensures precise engagement in threaded inserts and tapped holes, preventing cross-threading in production environments.
Specification Summary & Compliance
Manufactured to precise dimensional standards with UNC 8-32 threads featuring Class 3A fit for superior thread engagement. The assembly combines 18-8 Stainless Steel body with Acetal Plastic head (1/2" diameter, 7/32" height) in a fully threaded configuration. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence for global industrial applications.
