After regular use of a nut, you might lose its threads, and you may find it impossible to replace that because of various reasons. In that situation, repairing the thread is always a good idea, and you can easily repair that using a tap and die set. But if you do not know how to use best tap and die set for repair thread, then following are few simple steps that are mentioned below, and you can do the repair work easily.
Identify threads needed per inch:
This is the first step that you need to take for repairing the thread using any tool. You need to know the required thread per inch in the nut. You can use a proper gauge to identify the threads needed for a bolt or nut, and you can use a taper die accordingly. You will find details of the treads per inch information on the tapper die so you will not have any trouble with this selection.
Fix the nut and die:
To create threads into the bolt, you may need to place the bolt into a vise so you can hold it securely. If your bolt is already fixed at a place in non-movable position, then you can skip this part. After that, you also need to fix your taper die into a special wrench that allows you to make threads easily by rolling it around the bolt. This process is quite simple and easy to follow, so you will not find any trouble doing this.
Create new threads:
To create new threads on your existing bolt, put your taper die on the bolt and now start turning the wrench on the bolt. It will start creating new threads on the bolt, and if there are any remain of existing threads, then it will remove that as well. In order to do it properly make sure after making few threads you turn the wrench in reverse direction for a couple of rotation. It will clear the wrench, and you will be able to make better threads.
You need to understand that cutting metal always increases the heat and use of oil as a lubricant can help you do it better. Also, this oiling will reduce the chances of damaging your tapper die. Hence, it is a good idea that you keep applying the oil with regular interval. Other than this, it is also a wise idea that you check the fitting of the bolt after making few new threads. This check will give you an assurance that your new threads fix well with your bolt.
Finalize your work:
When you are done creating the threads until the end, then slowly rotate your wrench in the backward direction. If you have any residue of metal remaining on the bolt you can clean that using water oil or cloth. This will make it easier for you to fix the bolt on newly created threads and it will be easier for you to use it. Therefore make sure you do not skip this step because of any reason.
This process is easy and anyone can easily repair threads with the right tool. But you also need to understand that this process may not give you another chance of correction. If you are repairing the threads of a bolt that is fixed or welded, then you will need to do it correctly for the first time. So, make sure you take your actions wisely, and you will be able to do it in a perfect manner.
