When assembling structures made from Rexroth structural aluminum framing (MGE), the Central Bolt (AKA Connection Screw) is absolutely the simplest connection for fixedpoint right angles! This video uses 45series Rexroth profile, but will work with any Rexroth profile that has a 10mm Tslot.

9.8mm clearance hole should be drilled 18.5mm from the cut edge of the profile, centered in the Tslot. (Drilling jig also available, see link below)

This demonstration assumes an end cap will be added to the assembly, and uses the following items:

Connection Screw, M12x30: https://shop.flexmation.com/products/...
Connection Screw, S12x30 (selftapping): https://shop.flexmation.com/products/... This style of screw can be used with an impact wrench in cases where a tapping bit is not available. Assembly instructions are the same, but pretapping of the profile is not necessary.
