-#### Locking Effect Explained:
117
-
118
-Tightening the Screw:
119
-
120
-As you tighten the screw into the T-nut, the screw's threads engage with the internal threads of the T-nut.
121
-When the screw is turned, it applies a force that presses the T-nut tightly against the sides of the aluminum extrusion's groove.
122
-
123
-Increased Friction:
124
-
125
-The horizontal part of the T-nut, the "T" portion, makes contact with the two sides of the groove. This creates a large contact area between the T-nut and the extrusion.
126
-As the screw continues to tighten, the pressure between the T-nut and the groove increases, resulting in higher friction. The friction prevents the T-nut from moving within the groove.
127
-
128
-Stability:
129
-
130
-The tightening force from the screw effectively locks the T-nut into place. The T-nut's "T" shape, combined with the increased pressure, causes it to grip tightly inside the extrusion, which prevents it from shifting or loosening.
131
-This means that once the screw is fully tightened, the T-nut is securely fixed within the extrusion, providing a stable and non-moving connection.
132
-
133
-Prevention of Movement:
134
-
135
-The combination of friction and compression ensures that the T-nut will not slide or move within the extrusion slot. It becomes firmly anchored, even under load, ensuring the connection stays intact over time.
136
-In summary, the locking effect is the result of the screw creating a compressive force that increases friction between the T-nut and the aluminum extrusion groove, securing the T-nut in place and preventing it from shifting. This guarantees a strong, stable, and secure connection.

-- [[screws-dat]]
141
-
142
-Description: A hexagonal-shaped head that requires a wrench or a socket driver for tightening.
143
-
144
-Why it's preferred: The hex head provides a large surface area for torque, allowing you to apply more force to tighten the screw securely. This helps achieve a stronger locking effect for the T-nut.
145
-
146
-Application: Suitable for heavy-duty applications where a high level of torque and secure fastening is required.
