The M4 Drop-in T-Nut is a precision-engineered fastening component designed for use with T-Slot and V-Slot Aluminium Extrusion Profiles of the 20 series, including 2020, 2040, 2060, and 2080 types. Made from high-quality stainless steel, this drop-in T-nut ensures strong, secure, and corrosion-resistant connections in modular frame assemblies. It’s ideal for both new installations and existing frame systems, allowing easy insertion from the side of the profile groove without the need to dismantle the structure.

Perfect for use in 3D printers, CNC machines, laser cutters, and robotics, this T-nut provides exceptional versatility and stability for both professional and hobbyist applications.

Features:

• High-quality stainless steel construction for strength and durability

• M4 threaded T-nut compatible with 2020, 2040, 2060, and 2080 aluminium profiles

• Drop-in design allows lateral insertion into the profile groove—ideal for assembled frames

• Secure and stable fastening with grooved surface for anti-slip performance

• Corrosion-resistant anodized finish ensures long-term reliability

• Perfect for linear motion systems, mechanical frames, and modular structures

• Reusable and easy to install — no disassembly required

• Compatible with standard M4 screws, bolts, and fittings
