System 28 Flush Mount Bolt Without Slot
The System 28 Flush Mount Bolt Without Slot is a countersunk connection bolt designed for connecting System 28 / D28 aluminum profiles and fixture components.
Its flush-mounted head design allows the bolt head to disappear into the borehole, creating a smooth surface without protrusions. The adapted collar design makes it especially suitable for clamping aluminum profiles.
