Ever wondered how T-slot nuts lock securely into place? The secret lies in their unique design. When you slide a T-slot nut into the T-slot of a frame, it fits snugly. Once positioned, tightening a bolt or screw draws the nut against the side of the slot. This action creates a strong grip, preventing any movement.
Key Steps in the Locking Process:
1. Insertion: Slide the T-slot nut into the slot.
2. Positioning: Move it to the desired location.
3. Tightening: Use a bolt or screw to secure it firmly.
The bolts and screws play a crucial role here. They not only hold the T-slot nut in place but also provide the necessary pressure to keep everything stable.
Now, let’s compare T-slot nuts to slotted nuts. While both serve as fastening solutions, they have distinct differences.
● Design:
○ T-Slot Nuts: Feature a T-shaped profile for sliding into slots.
○ Slotted Nuts: Have a simple, flat design with slots for a wrench.
