DIN 7643 banjo bolts combine fastening and fluid transfer in a compact component. An axial bore connects with radial holes to allow fluid to pass between the bolt and the surrounding banjo fitting. The hexagon head supports straightforward installation, making this design suitable for hydraulic, fuel, and lubrication connections where installation space is limited.
Manufactured from Q235 carbon steel, our standard models follow DIN 7643 dimensions and are available with yellow zinc or blue-white zinc plating. Custom versions are available with different materials, lengths, hole configurations, and surface finishes to meet specific equipment requirements.

The axial bore and radial holes create an internal flow path while the bolt secures the banjo fitting, combining two functions in one component.
The banjo fitting sits around the bolt body, providing a compact connection for equipment with limited pipe-routing space.
Standard models are manufactured to DIN 7643 dimensions, supporting consistent specification and selection of matching components.
Available machining options include 1, 2, 3, 4, and 6 radial holes. Hole diameter and position can be specified according to the required drawing.
Yellow zinc and blue-white zinc plating are available for standard supply. Other surface treatments can be specified to suit application requirements.
Q235 carbon steel is the standard material. Alternative materials, thread dimensions, lengths, and hole patterns are available for custom orders.
Our engineers review your drawings and confirm bore diameter, hole position, and thread details before production starts.
Radial holes are drilled and deburred to the specified diameter and position for smooth, unrestricted fluid flow.
Q235 carbon steel is standard, with alternative material grades available for specific pressure and media requirements.
Yellow zinc and blue-white zinc plating as standard supply, with other finishes specified to match the working environment.
Thread sizes, lengths, hole patterns, and body dimensions are manufactured according to customer drawings.
Thread gauging and dimensional checks are carried out batch by batch to keep every shipment consistent.
| Connection Metric | Solid Bolt + Elbow Fitting | Our DIN 7643 Banjo Bolt |
|---|---|---|
| Flow Path | External elbow required | Integrated axial bore and radial holes |
| Potential Leak Points | Multiple threaded joints | Washer-sealed faces only |
| Installation Space | Extra room for elbow rotation | Compact inline connection |
| Assembly Steps | Multi-part alignment | Fit, rotate, and torque in one step |
| Component Count | Bolt + elbow + nipple | Single hollow bolt |
Our standard material is Q235 carbon steel. Other materials are available upon request for custom orders.
The dimensional range includes selected metric fine-thread sizes from M8×1 to M45×1.5. Dimensions and lengths depend on the selected model.
Yes. We can manufacture versions with 1, 2, 3, 4, or 6 radial holes. Hole diameter, position, and arrangement are confirmed according to the product drawing.
Standard options include yellow zinc and blue-white zinc plating. Other surface finishes can be customized upon request.
A typical banjo connection uses sealing washers on both sides of the banjo fitting. The bolt thread provides the clamping force, while the washers seal the mating faces.
Yes. We support drawing-based customization of materials, threads, lengths, hole configurations, and surface finishes.
