What is a hollow bolt?
The Hollow Bolt is a patented method of securing to square, rectangular or circular hollow section steel, or to conventional steel work where access is available from one side only.
banjo bolt
The base of the hollow bolt is a regular hexagon, with symmetrical depressions on both sides of the regular hexagon, forming an arc. The upper part is a cylinder, and the top has external threads.
Automobile hollow screw
The middle part of the utility model is a hollow cylinder. When in use, the screw passes through the hollow bolt, and the external protrusion on the screw is stuck at the top of the hollow bolt.
banjo screw
After the external thread on the hollow bolt matches the internal thread in the shaft hole, the upper part of the screw is fixed in the sleeve shaft, and the sliding rod can slide along the arc concave edge.
Hollow bolts are mostly used for connection sealing in oil and water delivery pipes. They feature a dual function of fastening while still allowing for a medium flow through them. Hollow bolts are widely used in engine fuel supply systems for automobiles, ships and machinery.
How do hollow bolts work?
A typical connection is made by inserting the hollow bolt into the pre-drilled holes of the fixture and hollow section. As the
bolt head is tightened, the cone is pulled up the bolt thread, causing the sleeve to expand until the cone locks the sleeve
against the hollow section's inner wall.
