BIG-SERT  Kits

     BIG-SERT inserts make it possible to save badly damaged threaded holes. They are also immensely strong and are sometimes used to extract maximum strength from light castings.
   The larger outer surface area of the BIG-SERT insert greatly increases the load-bearing capacity of the part into which they are installed.

 

  BIG-SERT kits are the same professional machinist quality our customers expect. They are commonly used to repair threaded holes that have been badly damaged by the attempted installation of lessen quality and more difficult-to-use thread repair products. Once you have used a TIME-SERT kit, you will understand why they are the best.

                    Note: Insert lengths included with the kits are underlined, italicised & RED.
