- Industry-compliant manufacturing meeting both REACH and RoHS 3 environmental standards
- Optimized grip surface with 3/8" external hex drive for standard tool compatibility
Professional Applications & Engineering Value
This female to female hex thread adapter solves critical connection challenges in industrial assembly where directional thread adaptation is required. The black-oxide steel construction provides essential corrosion protection for machinery exposed to moisture, chemicals, or outdoor conditions, while the Rockwell B80 hardness ensures the adapter maintains structural integrity under repeated torque applications. The external hex drive design with substantial 2" length allows mechanics to apply significant torque without damaging the fastener, making it ideal for automotive, manufacturing, and heavy equipment maintenance. The precision Class 2B thread fit guarantees secure mating between components, preventing loosening from vibration - a common failure point in industrial settings.
Specification Summary & Compliance
This adapter features precise 1/4"-28 thread sizes with Class 2B thread fit on both ends, ensuring standardized compatibility across industrial components. The manufacturing process adheres to REACH (EC 1907/2006) compliance for substance restrictions and RoHS 3 (2015/863/EU) compliance with exemption 6(a) for lead as an alloying element in steel. The external hex drive measures 3/8" across flats with a 2" length for optimal tool engagement, while the 1/2" thread length on both ends provides sufficient engagement depth for secure connections.
