Priced Individually TIME-SERT Big-Sert which is over sized, part number 51407A. Aluminum 14x1.25 washer seat insert with 16.8mm reach - considered 3/4" reach. 51407A.

Question - Why is there a chunk missing out of the side of the insert?

Answer - The piece missing is NOT a defect. Time-Sert calls this part of the insert the "socket with metal locking pin". It is an engineered locking design. Once the insert is installed with the driver, the locking pin is pushed out and locks the insert into place. This creates a "cam lock" which helps to insure the insert will NOT back out.
