Professional Applications & Engineering Value
This 10-24 UNC thumb screw addresses critical assembly challenges in industrial maintenance and equipment manufacturing. The steel construction with Rockwell B55 hardness provides exceptional wear resistance for high-cycle applications, while the fully threaded design ensures maximum grip length for vibration-prone environments. The spade head configuration enables rapid manual operation without tools, significantly reducing maintenance downtime in electronic enclosures, machinery panels, and access covers. The coarse threading (UNC) combined with Class 2A thread fit delivers reliable engagement in both metallic and composite materials, making these thumb screw fasteners ideal for prototyping, production lines, and field service applications requiring frequent adjustments.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNC thread specifications. The 10-24 thread size features 0.19" major diameter with coarse thread spacing. All components comply with RoHS 3 (2015/863/EU) environmental regulations, ensuring restricted substance compliance for global industrial applications. The 3/8" length and fully threaded construction maintain consistent mechanical properties throughout the fastener length.
