Hi,
Such a “Nut” as you call it is not difficult to make even if you only have a rudimentary workshop and possibly welding gear. I was faced with this situation the first time our son visited with his prospective wife in her latest car that had a slow puncture, was fitted with locknuts, had no spare and no release key. You will need preferably for convenience some hex bar from your bits box of suitable size to fit into a socket or a suitable bit of metal to which can be fitted a handle and hardened steel dowel of a size to closely fit in the holes – I keep broken off drills for this type of application. If you are good at measuring then carefully work out the angular relationship and dimensions of the head of the screw and mark out on the hex bar. It is often easier to take a rubbing on some card of the screw so that you can transfer the position of the holes by simply striking with a centre punch through the centre of each hole onto the hex bar/suitable piece of metal. Fit this upright in a bench vice and drill each hole using a pedestal drill. A rule of thumb would be four diameters deep to avoid pull-out under load. It is usually better to start with the next size down (~0.5 mm smaller) for each hole then open up to the required size with the correct drill. If you have a metric hole size requirement then it is often possible to find an Imperial size just smaller than required such that you can create a “drive fit” for the dowel. Cut three pieces of dowel (use a grinder or angle grinder if it is really hard) just slightly longer than the combined hole depth in the screw and the depth in your hex bar and press each one into its hole using a vice or Loctite in place if you have a clearance hole. Finish by grinding as little as possible off the dowels to get them all to the same height and finely chamfer their edges and there you have it! In other cases where it would not be so easy to use the method described above, it is then necessary to weld the dowels into a piece of tube with the dowels inserted into the screw – as was the case described in the first paragraph. Once positioned the hex bar was welded into the tube. The total time of manufacture was ~30 mins, most of which was finding the material. This tool proved reliable enough to be used for the next few years until the car was finally sold. Hope this helps.

Hi. I have lost a nut that fits the following. Please see the pictures. Does anybody know where I can get my hands on one?
