20 Series M4 T-Nut European Standard Aluminum Profile Hammerhead

The European Standard 20 Series M4 T-Nut is an essential fastening component designed specifically for standard 20mm aluminum extrusion profiles. These hammerhead nuts, also known as boat-shaped or drop-in nuts, offer a versatile solution for building 3D printer frames, CNC machine structures, and industrial workstations. Manufactured from high-quality carbon steel with a durable nickel-plated finish, they provide excellent strength and superior corrosion resistance. The hammerhead design allows for convenient post-assembly installation, as the nut can be dropped directly into the profile slot at any point and automatically rotates 90 degrees to lock securely when tightened with an M4 bolt. This unique mechanism ensures a rigid and vibration-resistant connection, making them a preferred choice for precision DIY projects and robotics.

Features:

• Post-Assembly Insertion: Hammerhead design allows nuts to be dropped into the profile slot after the frame is already assembled.
• Automatic Locking: Rotates 90 degrees clockwise upon tightening to lock securely behind the slot edge.
• High-Quality Material: Constructed from carbon steel for robust mechanical performance.
• Corrosion Resistance: Nickel-plated surface finish prevents rust and ensures a long service life.
• Universal 20 Series Fit: Specifically compatible with European standard 2020 series aluminum extrusions.
• Precision Threading: Features clean M4 metric internal threads for smooth fastening with standard machine bolts.
