Description
Technical Overview
The 5 Hole 90 Degree Joining Plate – 40 Series functions efficiently as a structural planar connection component. Specifically, engineers design this hardware to join intersecting 40 Series T-Slot aluminium extrusion profiles. Consequently, the component establishes rigid right-angle joints across the structural framework assembly.
To ensure a resilient and stable layout, the manufacturer constructs this plate from durable aluminium. Furthermore, the design incorporates a flat 5-hole mounting configuration that actively optimizes force distribution across the profile tracks. During system assembly, technicians mount the plate directly over the joint interface using standard fasteners. Therefore, this precise configuration significantly simplifies mechanical alignment and provides flat, secure reinforcement without requiring secondary machining modifications.
Applications
Technicians regularly deploy these joining plates at the planar intersections of various modular structures. Specifically, assembly teams utilize these multi-hole reinforcing components to secure right-angle corners and planar sub-assemblies built from standard 40 Series T-Slot profiles. For example, operators install the flat adapters on the frame corners of automated machinery setups, safety guarding enclosures, material handling systems, and custom industrial workstations.
Within these demanding manufacturing environments, completed custom frames strictly require external joint reinforcement to resist shear forces and operational vibrations. This flat 5-hole profile handles physical loads flawlessly because it distributes stress evenly across the intersecting tracks to prevent twisting under load. Meanwhile, builders must note that the plate mounting layout matches 40 Series family constraints exactly. As a direct result of these unalterable boundary constraints, this hardware configuration does not interface with smaller 20 Series V-Slot extrusion framing layouts.

Maker Store Tips and Tricks
-
Hand-tighten all five fasteners lightly into the T-slot nuts before completing final torque application to achieve parallel alignment across both extrusion faces.
-
Pair this joining plate with low-profile or button-head screws to preserve a flat clearance height on the exterior faces of your frame assembly.
-
Verify that the intersecting 40 Series extrusion rails are cut square at exactly 90 degrees to optimize surface contact underneath the plate layout.
What makes T-Slots such an easy assembly task?
Building frames out of T-Slot extrusions is easy because they eliminate the need for specialized tools or welding, simplifying the assembly process. Building frames using T-Slot Linear Rail will require;
- 40 Series T-Slot Extrusions: These are the main structural components, usually made of aluminium, with slots along their lengths that allow you to easily connect various parts and accessories.
- 40 Series Brackets and Connectors: These are specialized components designed to fit into the T-Slot extrusions and secure them together at various angles. They include corner brackets, T-nuts, L-shaped brackets, and other connectors.
- Fasteners: Bolts, screws, and nuts are required to attach the brackets and connectors to the T-Slot extrusions securely.
- Tools: Basic hand tools like wrenches, Allen keys (hex keys), and screwdrivers are necessary for assembly. Additionally, a saw may be needed to cut the T-Slot extrusions to your desired lengths.
