S-91998A105 Left-Hand to Right-Hand Female Hex Thread Adapters

Key Features & Benefits at a Glance

• Enhanced Durability - Black-oxide steel construction provides superior corrosion resistance for extended service life in harsh industrial environments.
• Optimal Torque Transmission - 3/8" external hex drive and 1 1/2" hex length ensure maximum torque application without slippage during assembly.
• Precision Thread Engagement - Class 2B thread fit on both ends guarantees secure, reliable connections with minimal risk of cross-threading.
• Consistent Mechanical Strength - Rockwell B80 hardness maintains structural integrity under repeated stress and vibration.
• Versatile Connection Solution - Female-to-female hex design adapts thread direction between components without compromising flow or alignment.
• Regulatory Compliance Assurance - REACH and RoHS 3 compliance meets international safety and environmental standards for industrial applications.
• Standardized Compatibility - 10-24 threading on both ends ensures seamless integration with existing industrial fastener systems.

Professional Applications & Engineering Value

This female-to-female hex thread adapter solves critical alignment and connection challenges in industrial assembly lines, machinery maintenance, and pneumatic systems. The black-oxide steel surface treatment provides exceptional corrosion resistance where lubricants or environmental factors degrade standard finishes. With Class 2B thread fit precision, it eliminates play in high-vibration applications while the Rockwell B80 hardness ensures the adapter withstands repeated torque cycles without deformation. Engineers value its ability to maintain thread direction adaptation in confined spaces where component reorientation is impractical, making it indispensable for retrofitting equipment and creating custom fluid/power transmission pathways.

Specification Summary & Compliance

Manufactured to precise Class 2B thread fit standards for consistent engagement accuracy. The adapter meets REACH (EC 1907/2006) compliance for substance restrictions and RoHS 3 (2015/863/EU) compliance with exemption 6(a) for lead as steel alloying element. Thread specifications maintain 10-24 threading on both ends with identical 3/8" thread length for balanced connection strength. External hex drive dimensions (3/8" size, 1 1/2" length) conform to industrial drive tool standards.
