Professional Applications & Engineering Value
This female hex thread adapter solves critical connection challenges in precision assemblies where different thread sizes must interface reliably. The Black-Oxide Steel construction provides essential corrosion protection for industrial environments while maintaining dimensional stability. Engineers benefit from the Class 2B thread fit on both 4-40 and 6-32 ends, ensuring consistent engagement without cross-threading risks in automated production lines. The external hex drive with 1" length offers superior torque application capability compared to standard fasteners, making it ideal for maintenance applications in confined spaces. With its 75000 psi tensile strength and Rockwell B65 hardness, this adapter maintains performance integrity in vibration-prone equipment, electrical enclosures, and precision instrumentation where connection failure is not an option.
Specification Summary & Compliance
This inch-system adapter features precision Class 2B thread fit on both 4-40 (1/4" length) and 6-32 (3/8" length) connections, manufactured to ASTM A108 specifications for consistent quality. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(a)-I for lead as an alloying element in steel, meeting international environmental standards while maintaining required mechanical properties. All dimensional tolerances adhere to inch measurement standards with external hex drive compatibility for 3/16" tools.
