  • 4-40 thread insert

    Does anyone know where to buy the inserts used in classic slot car that push into the body, and then retain the chassis with 4-40 screws?

    I'm not sure if this will help you or not, but there's 7 pages of various slot car screws on the 132Slotcar website.

      Nope. I just looked, and they are all new metric hardware.

      The inserts look like small top hats; a tube with a flange on one end. The outside is knurled, and the inside is 4-40 thread. You push the insert into the plastic tube on the inside of the body until the flange touches the end of the plastic. Then you seat a 4-40 screw into the insert thru the flange. This spreads the tube to expand it and the knurling grips the plastic so it doesn't come out. That makes the screw removable so you can then mount the chassis with the screw. There are usually 3 of these used to hold the chassis to the body.

        You can check McMaster-Car under 4-40 threaded inserts for plastic to see if any of theirs would work, They have a bunch listed.

          Thanks Van. They have them under Flanged Screw-to-Expand Inserts for Plastic

          McMaster-Carr in brass, and even in aluminum!

            Try Slot Car Corner under Bodies and Body Parts, then Body Post Repair.

              You can also get them and the 4-40 screws at most ACE Hardware stores.

                  I went to the largest local Ace, and they didn't have the inserts, and couldn't find them on their web page either. So, back to on line or McMasters

                    We have 3 stores that I know of here (Portland) that have them. I find them in the little bins in the bulk screw section.

                    Maybe it is a regional thing.

                      I have been looking everywhere for the 4-40 thread inserts, but to no avail!

                      Slot car C..... has repair kits in M2, which is too small for the size I need.


                      If anyone on the site can pick up 6 or so for me, and puit them in a padded envelope, I'll send you payment by paypal, check, or even cash in the mail!

                          Professor Motor and Slot Car Corner have several types/styles to choose from. Just type in "body post repair" in the search bar.

                            I did a search on Prof Motor, and they are selling the same Slot Car cnr kits. They are the 2mm, which is too small compared to the 4-40.

                              I PMed the OP with an eBay find the same as what Ace offers.
                              As for Ace, the listing is for Brass Flange Insert, PN 930451-K. They would be in the brown small parts bins marked Household 45.55.
                              If your local store doesn’t stock them, they may be able to order in packages of 10.
                              My local Ace does not have them.
                              Do not confuse what the OP is looking for with threaded inserts for wood. These have a deeper and coarser thread that would probably destroy the body post.

                              As an alternative, why not plug the post with Evergreen styrene tube or rod, then drill and tap for 4-40? A few drops of ACC and retapping should make for fairly hard threads. Or fill with JB Weld and do the drill and tap thing.
