Professional Applications & Engineering Value
This female hex thread adapter solves critical challenges in machinery assembly, plumbing, and automotive systems where mismatched inch thread sizes cause operational delays. Crafted from black-oxide steel with Rockwell B65 hardness, it withstands repetitive stress and corrosive conditions, eliminating the need for custom fittings. The Class 2B thread fit maintains alignment under vibration, while the external hex drive simplifies adjustments in confined spaces. Ideal for converting 5/16"-18 to 3/8"-16 connections in hydraulic systems, conveyor setups, and industrial equipment, it ensures reliable thread adaptation without compromising structural integrity.
Specification Summary & Compliance
This adapter adheres to Class 2B thread tolerances for both 5/16"-18 and 3/8"-16 ends, manufactured under ASTM A108 specifications. It complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) with exemption 6(a) for lead as a steel alloying element, ensuring environmental and safety standards are met for industrial use.
