• Rockwell B85 hardness rating maintains thread integrity and prevents deformation during repeated installation and removal cycles
• External hex drive with 13mm hex size allows for easy installation and removal using standard metric tools, reducing assembly time
• Dual metric thread adaptation (M8×1.25 to M5×0.8) enables seamless connection between different sized components without compromising system integrity
• RoHS 3 compliance with exemption meets international environmental standards while maintaining required mechanical properties

Professional Applications & Engineering Value

This metric-to-metric female hex thread adapter solves critical connection challenges in industrial assembly where different thread sizes must interface reliably. The zinc-plated steel construction combined with ASTM A108 compliance ensures consistent performance in automotive, machinery, and equipment manufacturing applications where vibration resistance and corrosion protection are essential. The precision Class 6H thread fit on both M8×1.25 and M5×0.8 ends eliminates play and maintains alignment in dynamic load conditions. With its external hex drive and optimized thread lengths, this adapter enables quick field modifications while providing the 78,000 psi tensile strength needed for heavy-duty industrial use, reducing downtime and maintenance costs.

Specification Summary & Compliance

This adapter features precision Class 6H thread fit on both metric ends (M8×1.25 and M5×0.8) with thread lengths of 16mm and 12.7mm respectively. Manufactured to ASTM A108 and ASTM B633 specifications using zinc-plated steel, it maintains dimensional accuracy and mechanical properties. The adapter is RoHS 3 (2015/863/EU) compliant with exemption 6(a)-I for lead as an alloying element in steel, ensuring environmental compliance without compromising performance. The external hex drive features a 13mm hex size with 50mm length for standard tool compatibility.
