Hex Head Bolts with a hollow shaft, also known as Hollow Shaft Hex Bolts or Tubular Bolts, are specialized fasteners that have a hollow core through the length of the bolt. This design is not as common as solid-shaft bolts but serves specific applications where weight savings or special functionality is required.
Applications:
Weight-Sensitive Applications:
The hollow shaft reduces the overall weight of the bolt without significantly compromising its strength. This can be important in industries such as aerospace, automotive, and motorsports, where every gram counts towards performance and efficiency.
Through-Bolt Applications:
In scenarios where the bolt needs to pass through a component or assembly, the hollow shaft can allow for the passage of wires, cables, or other components inside the bolt itself. This can be useful in electrical enclosures, conduit installations, or machinery where space is at a premium.
Specialized Machinery:
Certain machines may require bolts that serve dual purposes, such as providing both mechanical fastening and allowing fluid or air to flow through them. Hollow shaft hex bolts can be used in pneumatic systems, hydraulic equipment, or any application requiring internal passages within the fastener.
Decorative or Architectural Elements:
In architectural designs or decorative assemblies, the hollow shaft might be used to conceal fasteners or create a seamless appearance by hiding elements like pins or dowels within the bolt.
Pipe and Tubing Connections:
These bolts can sometimes be utilized in pipe flange connections or tubing assemblies where they need to fit around existing piping or when the bolt's reduced diameter due to the hollow core allows for tighter clearances.
Considerations:
Strength vs. Weight: While hollow shaft bolts can reduce weight, they generally offer less tensile strength compared to solid-shaft equivalents. Engineers must ensure that the chosen bolt will withstand the expected loads.
Corrosion Resistance: Depending on the environment, it might be necessary to select materials or coatings that provide adequate protection against corrosion, especially since moisture could potentially accumulate inside the hollow shaft.
