- Extended connection capability with 48mm extra long profile for joining threaded rods or bolts over greater distances
- Superior corrosion resistance thanks to 18-8 stainless steel construction, ideal for harsh industrial environments
- Precision thread engagement with Class 6H fit ensuring reliable, vibration-resistant connections
- Easy installation and removal with external hex drive design for standard wrench compatibility
- Optimized load distribution through partially threaded design that maintains structural integrity
- Enhanced grip strength with coarse 1.25mm pitch threading that resists loosening under dynamic loads
- Regulatory compliance assurance meeting both REACH and RoHS 3 environmental standards
Professional Applications & Engineering Value
This extra long coupling nut solves critical connection challenges in industrial assembly where standard nuts fall short. The M8 x 1.25mm coarse thread configuration provides exceptional holding power in high-vibration applications while the 18-8 stainless steel material offers reliable performance in corrosive environments. Engineers specify this partially threaded coupling nut for extending threaded rods, creating custom-length fasteners, and bridging gaps in structural frameworks. The 48mm length and Class 6H precision threads ensure perfect alignment and maximum thread engagement, preventing connection failure in heavy-duty mechanical systems, construction projects, and manufacturing equipment where reliable long-span connections are essential.
Specification Summary & Compliance
This metric coupling nut features M8 x 1.25mm coarse threading with Class 6H thread fit tolerance per ISO standards, ensuring precise dimensional accuracy. The 16mm minimum thread length provides sufficient engagement for secure connections. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, guaranteeing environmental responsibility. The external hex drive (13mm width) and partially threaded design meet industrial fastener specifications for reliable performance in demanding applications.
