Metal star blades are designed to be inserted into steel tube feet.
When inserting the threaded insert into the tube, the star washer/clip usually bends to bend in the direction of entry. Then, the edge of the clamp bites into the inner diameter of the pipe to provide firm support.
The outer edge is flush with the outer edge of the pipe to provide a neat appearance.
Quantity: 10pcs inserts.
