System 28 Flush Mount Bolt
The System 28 Flush Mount Bolt is a high-strength hidden connection bolt designed for connecting System 28 / D28 welding table components and fixture elements.
Its unique design allows the bolt head to disappear into the borehole, creating a flush surface connection without interfering with the workpiece or fixture setup. It is ideal for connecting multiple components while maintaining a clean and compact fixture structure.

Product Description
The System 28 Flush Mount Bolt provides a clean and secure connection between modular welding fixture components.
Unlike standard connecting bolts, the bolt head is recessed into the borehole, allowing connected components to remain flush and preventing interference during welding and assembly operations.
The bolt is tightened using a hexagon socket (Size 6) and provides high clamping force with excellent stability.
Important Notes
Do not use in elongated holes
Do not use for connecting welding tables or U-shaped squares
Clamping torque depends on the table type and component combination
Applications
Suitable for:
Connecting System 28 fixture components
Modular welding fixture construction
Multi-layer fixture assemblies
3D welding setups
Precision fabrication fixtures
Custom jig construction
