Key Features & Benefits at a Glance
- Dual-thread versatility enables seamless connections between coarse (UNC) and fine (UNF) thread components, reducing inventory needs and assembly time
- Exceptional 150,000 psi tensile strength withstands extreme mechanical loads in demanding industrial applications
- Class 3A precision threads ensure superior fit and vibration resistance compared to standard Class 2A fasteners
- Black-oxide surface treatment provides corrosion resistance while maintaining dimensional accuracy
- Rockwell C39 hardness rating guarantees excellent wear resistance and long-term durability
- Hex drive compatibility allows for secure installation using standard industrial tools
- Alloy steel construction delivers optimal strength-to-weight ratio for critical structural applications
Professional Applications & Engineering Value
This dual-threaded rod solves critical interface challenges in machinery assembly, automotive manufacturing, and precision equipment. The UNC 1/4"-20 coarse thread end provides rapid assembly and superior resistance to vibration loosening, while the UNF 1/4"-28 fine thread end delivers precise adjustment capability and enhanced sealing performance. Manufactured from black-oxide alloy steel, this component maintains dimensional stability under heavy loads while the oxide coating prevents galling and corrosion in industrial environments. Engineers specify this solution for applications requiring both robust fastening and fine-tuning capabilities within space-constrained assemblies.
Specification Summary & Compliance
This threaded rod features Class 3A thread fit on both ends, exceeding standard commercial tolerances for precision applications. The UNC/UNF thread combination complies with ASME B1.1 standards, while the 150,000 psi tensile strength meets industrial requirements for high-stress applications. The black-oxide finish provides corrosion protection without compromising thread dimensions. Manufacturing follows industry standards for alloy steel fasteners and complies with RoHS and REACH environmental directives.
