- Convenient External Hex Drive – The 1/4" hex design allows for easy installation and removal using standard tools, streamlining maintenance and adjustments.
- Compliant with Industry Standards – Meets ASTM A108 and RoHS 3 requirements, ensuring material quality and environmental safety for global supply chains.
Professional Applications & Engineering Value
This Inch-to-Metric Female Hex Thread Adapter solves critical challenges in mixed-standard assemblies, such as in machinery, automotive, and electronics manufacturing. Crafted from zinc-plated steel, it resists corrosion in humid or outdoor conditions, while the Rockwell B85 hardness prevents thread stripping under torque. The precise Class 2B and 6H thread fits ensure leak-proof and stable connections, reducing rework and downtime. Ideal for adapting equipment with 6-32 to M4 threads, it enhances compatibility across international components, supporting efficient production lines and maintenance operations without compromising on 78000 psi tensile strength.
Specification Summary & Compliance
This adapter maintains tight dimensional accuracy with Class 2B (inch) and Class 6H (metric) thread tolerances, adhering to ASTM A108 and ASTM B633 manufacturing standards. It is RoHS 3 (2015/863/EU) compliant under exemption 6(a)-I for lead as an alloying element in steel, ensuring regulatory alignment for industrial use.
