90 Degree Inside Corner Connector – 40 Series

$3.10 Inc. GST

This right-angle internal fastening component, manufactured from cast zinc alloy or cast aluminium, slides directly into the internal channels of 40 Series T-Slot linear profiles to establish a concealed, flush mechanical joint. Secured internally within the extrusion channel using integrated M6 set screws, its primary function is to maintain structural perpendicular alignment without obstructing the external faces of the framing. Typical applications include industrial framing, machinery enclosures, CNC machine frames, and linear motion assemblies where hidden joints are required to maximize external mounting area or support flush panel installations. This hardware interfaces exclusively with 40 Series T-Slot profiles and is incompatible with 20 Series V-Slot footprints.

Description

Technical Overview

The 90 Degree Inside Corner Connector establishes structural right-angle junctions within modular framing systems. Specifically, this component slides directly into the internal channels of 40 Series T-Slot linear profiles. As a result, it creates a completely concealed, flush mechanical joint. Additionally, manufacturers construct the connector body from cast zinc alloy or cast aluminium. This composition allows the unit to handle substantial mechanical assembly loads with ease. Furthermore, the connector fastens securely inside the extrusion channel. It achieves this tight grip by using integrated M6 set screws. Consequently, you ensure precise structural alignment while keeping the external face of the profile completely unobstructed.

Applications

Builders install this internal connector in industrial framing, machinery enclosures, and CNC machine frames. Moreover, they integrate the hardware into linear motion assemblies that rely on a 40 Series profile footprint. Teams primarily deploy this component where structural joints must remain hidden inside the profile channels. Therefore, they successfully maximize external mounting space for other accessories. Alternatively, this hidden placement supports smooth, flush panel installations across the frame. However, you must note that this hardware interfaces exclusively with 40 Series T-Slot linear extrusions. Consequently, it does not fit and is not compatible with 20 Series V-Slot profiles.

Maker Store Tips and Tricks

  • Slide the connector fully into the profile channel before securing to guarantee precise joint squareness.

  • Alternately tighten both M6 set screws gradually to apply even clamping pressure inside the T-slot.

  • Periodically verify fastener tightness in structural frames exposed to persistent vibrational loads.

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;

  1. 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.
  2. 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.
  3. Fasteners: Bolts, screws, and nuts are required to attach the brackets and connectors to the T-Slot extrusions securely.
  4. 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.
