Professional Applications & Engineering Value
This 3/8"-16 UNC thumb screw delivers critical advantages in applications requiring frequent adjustments or tool-free access. The spade head design enables high-torque hand-tightening, eliminating the need for drivers in equipment panels, access covers, and clamping fixtures. Manufactured from high-grade steel with Rockwell B55 hardness, it withstands repeated use without stripping or deformation. The fully threaded coarse UNC profile ensures maximum holding power in wood, metal, and composite materials, while the Class 2A thread fit guarantees smooth engagement in high-vibration environments. Ideal for industrial machinery, electronic enclosures, and commercial assemblies where reliability and quick maintenance are paramount.
Specification Summary & Compliance
This thumb screw adheres to UNC coarse thread standards with Class 2A thread fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) compliance for restricted substance control. Manufacturing specifications include a 3/8"-16 thread size, 1" length, and right-hand thread direction, ensuring compatibility with standard inch-system components and assembly requirements.
