122-2198 1 1/4″-7 Square Nut
Cat® Steel 1-1/4-7 Heavy Square Nut for Drag Conveyors
Description
The square nut is a fastener used in drag conveyors. It is designed to hold components together by threading them onto the roller bracket. Compared with a standard hex nut, this shape offers several advantages, including greater stability and resistance to rotation. It is found in drag and screw conveyors, where it is used to hold the roller supports in the drag conveyor system together. The square shape of the nut prevents accidental rotation, which is especially important in applications where vibration or movement is common, such as conveyor systems.
Attributes
- Prevents accidental rotation and provides stability in the assembly
- Strong and wear-resistant, suitable for heavy duty industrial applications
- Maintains the integrity and stability of components during material handling
- Designed to provide a larger contact area with the components it secures, distributing the load more evenly
Applications
This square nut is used in conveyors to securely hold the conveyor roller supports, preventing unwanted rotation and ensuring stability during bulk material handling.
