80/20 Inc. 33470 Hidden Corner Connector 30 40 Series

Product Description

The 80/20 INC. 33470 is a hidden corner connector designed for use with 30 and 40 Series T-slot aluminum framing systems. It creates a clean inside-to-outside corner joint while keeping the fastening hardware out of sight. The connector is made from zinc with a clear finish and uses an M6 thread for a secure, repeatable connection. Installation requires a 3mm hex wrench. At 0.053 pounds, it is a lightweight fastening component suited for modular frame assembly work performed by fabricators, integrators, and industrial maintenance technicians.

This connector is used in structural framing applications where a low-profile, concealed fastening method is preferred. The inside-to-outside style makes it appropriate for building enclosures, machine guards, workstations, and other assemblies where external fastener heads would interfere with panel fitment or aesthetics. It is compatible with 80/20 INC. 30 Series and 40 Series extrusion profiles and is typically used in light to medium-duty modular framing builds.

Installation Notes

Installation is typically performed by fabricators or maintenance technicians assembling T-slot framing structures. Disengage or de-energize any connected equipment before working on a structural frame assembly. Use a 3mm hex wrench to drive the connector; do not substitute a larger driver that could strip the fastener. Follow the framing system manufacturer guidelines for joint loading and fastener torque requirements.
