Standard Fasteners are a popular choice for connecting to aluminium profiles at a right-angle. A number of sizes are available which correspond to the line of aluminium profile used.
The necessary thread (b) is tapped directly into the core bore of the profile.
A drill hole (a) is required for the Hex key to access the fastener when it is in place.
