• Quick manual installation and removal with convenient wing head design, reducing tool dependency and assembly time
• Reliable thread engagement with Class 2A thread fit ensuring consistent fastening performance and vibration resistance
• Broad material compatibility from UNC coarse threading providing strong holding power in various substrates
• Full-length threading along the 1/2" length maximizes grip range and adjustment flexibility
• Precise dimensional control with head diameter tolerance of ±0.0156" for consistent fit in pre-drilled holes
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

This 10-24 UNC thumb screw delivers exceptional value in applications requiring frequent access or adjustment, such as electrical enclosures, machinery guards, and panel fastening systems. The zinc-plated iron construction provides essential corrosion protection where moisture or chemical exposure occurs, while the wing head design enables rapid hand-tightening without tools - crucial for maintenance efficiency. The fully threaded 1/2" length with coarse thread spacing ensures maximum thread contact in both thin and thick materials, preventing stripping and maintaining clamping force. Engineered with right-hand thread direction and standardized UNC threading, these screws integrate seamlessly into existing inch-system assemblies across manufacturing, electronics, and industrial equipment sectors.

Specification Summary & Compliance

This thumb screw features precision Class 2A thread fit per UNC standards with 10-24 thread size and 0.19" thread diameter. The 3/8" head diameter maintains dimensional stability within -0.0156" to +0.0156" tolerance. Manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for global industrial applications.
