Professional Applications & Engineering Value

This hollow threaded stud addresses critical engineering challenges in industrial assemblies where both secure fastening and internal routing capabilities are required. Manufactured from 18-8 Stainless Steel, it provides excellent corrosion resistance for applications in chemical processing, marine environments, and food equipment where moisture and corrosive agents are present. The UNC coarse thread design ensures rapid installation in high-vibration settings, while the Class 2A thread fit maintains precise tolerances for consistent performance. The 3/16" hollow diameter enables passage of electrical wires, lubrication lines, or cooling fluids through the fastener itself, eliminating the need for additional routing components and simplifying complex assembly designs. This combination of material properties and threaded rod configuration makes it ideal for machinery, structural frameworks, and specialized equipment requiring both mechanical strength and integrated functionality.

Specification Summary & Compliance
