Product Overview

The M3 T-Slot Nut is an essential mounting fastener designed for 20-series aluminum profiles with a 5 mm groove. Unlike standard nuts, the T-slot shape allows it to be slid into the profile channel from the end, providing a secure, threaded anchor point for brackets, sensors, and other accessories.

Constructed from high-strength steel with a zinc-plated finish, these nuts offer excellent pull-out resistance and durability for both static and dynamic frameworks.

Key Specifications

Technical Features

• Precision Threading: High-quality M3 internal threads ensure smooth fastening and prevent stripping under normal torque.

• Optimal Load Distribution: The T-slot design maximizes the contact surface area within the profile groove, distributing stress evenly across the aluminum channel.

• Corrosion Protection: The zinc-plated coating provides an industrial-grade barrier against oxidation and environmental wear.

• Low Profile Fit: Designed to sit flush within the 5mm slot, allowing for seamless mounting of external components without interfering with the profile's structural integrity.

💡 Tech Tip: For the most secure assembly, ensure your screw length is sufficient to engage at least 4–5 threads into the nut without bottoming out against the aluminum profile's inner core.

Ideal Applications

• Electronic Mounting: Securing PCB spacers, small sensors, or control boards to 3D printer frames.

• Light-Duty Bracing: Connecting lightweight 90° brackets or hinges to 2020 extrusions.

• Cable Management: Attaching zip-tie mounts or wire guides along the profile channels.

• Custom Tooling: Fixing guide rails or small jig components to modular workstations.
