Professional Applications & Engineering Value
This 3/8"-16 UNC low-profile knurled thumb screw delivers exceptional engineering value where frequent access and tool-free operation are critical. The 18-8 stainless steel construction provides outstanding corrosion resistance for industrial environments exposed to moisture, chemicals, or outdoor conditions. The knurled round head offers superior tactile grip even with oily hands or gloves, while the low-profile design minimizes protrusion in confined spaces. With UNC coarse threading and Class 2A thread fit, installation is rapid and secure, reducing assembly time in production lines, maintenance panels, and electronic enclosures. The partial threading allows for precise clamping force control, making it ideal for adjustable fixtures, access panels, and machinery where repeated adjustments are necessary without compromising structural integrity.
Specification Summary & Compliance
This thumb screw features precision 3/8"-16 UNC coarse threading with Class 2A thread fit for reliable engagement. Manufacturing complies with standard inch system specifications, delivering consistent dimensional accuracy. The component is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting current environmental regulations for industrial components. Mechanical properties include Rockwell B83 hardness and 80,000 psi tensile strength, ensuring durability in demanding applications.
