Professional Applications & Engineering Value
This female-to-female hex thread adapter solves critical connection challenges in industrial assembly and maintenance operations. The black-oxide steel construction provides superior corrosion protection while maintaining Rockwell B80 hardness for exceptional durability under repeated use. Engineered with 3/8"-16 Class 2B threads on both ends, this adapter ensures precise thread alignment when converting between left-hand and right-hand threaded systems. The external hex drive design allows for high-torque installation using standard industrial tools, making it ideal for hydraulic systems, machinery assembly, and equipment maintenance where reliable thread direction adaptation is crucial. The extended 3/4" thread length provides maximum engagement surface for secure connections in high-vibration environments.
Specification Summary & Compliance
This adapter features precision Class 2B thread fit on both 3/8"-16 threaded ends with 3/4" thread length. The external hex measures 1/2" across flats with 2 1/2" length for optimal tool access. Manufactured from black-oxide steel with Rockwell B80 hardness rating. Fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) standards with exemption 6(a) for lead as an alloying element in steel, ensuring environmental responsibility and workplace safety.
