Product Description
The L-shaped track double lug threaded stud is a custom fastener consisting of a double-eye connector and a threaded rod. Its key feature is the provision of symmetrical load-bearing points via the eye holes on both sides, making it suitable for connections subject to lateral or axial loads, such as tie rods, lifting eyes, and chains. These bolts offer secure installation and uniform stress distribution, making them widely used in applications requiring highly reliable tension and compression connections, such as construction machinery, lifting and hoisting, building scaffolding, and rail transit.

Product Features
This threaded clevis is commonly used wherever a component needs to move, pivot, or be adjusted. For example, it can connect hydraulic cylinders on construction equipment, linkage systems on agricultural machinery, or tension rods on industrial structures.
The forked design supports the load from both sides, helping to reduce stress and improve stability. This makes it a dependable choice for equipment exposed to vibration, repeated motion, or heavy working loads.
Simply adjust the nut position on the threaded rod to change the length or tension of the assembly. This feature is especially useful in support systems, tensioning applications, and adjustable linkage mechanisms.
Choose carbon steel for economical general-purpose applications or stainless steel for environments exposed to moisture, chemicals, or saltwater. Stainless steel versions are widely used in marine equipment, outdoor structures, and food processing machinery.
