How to properly shorten a bolt

Good advice and a useful trick on how to shorten a bolt, stud or screw. The fact is that if you cut the threads in the usual way, you will no longer be able to screw the nut back onto the threads. All this happens due to the fact that the threaded turns are wrinkled.

There is a simple way out to avoid this.

Will need


  • A bolt, stud or screw that needs to be cut and shortened.
  • Nut, 1-2 pcs., with the same thread.

Cutting a bolt, stud or screw correctly


So I'll take a screw as an example. Use a marker to mark the place for the cut. We measure with a ruler.

Screw 1-2 nuts onto the bolt beyond the mark. In general, the nuts should be on the side that you will need later.

Now let's cut it off. Depending on the thickness, this can be done in several ways:
  • Bite off with nippers.
  • Cut with a grinder.
  • Saw off with a hacksaw.
  • Clamp it into a screwdriver and rotate the bolt and cut it off with a hacksaw.
  • Or another way.

It's not important for you to choose.

I bit it off with wire cutters because the screw is thin. Of course, this is the crudest method, but it is fast.

Now hold the nut with pliers and use a screwdriver to remove the screw.This is the trick: after unscrewing, the nut will straighten all the threads at the tip of the cut.

It is better to screw on two nuts; they will better correct the entire thread.

Now, you can easily screw nuts onto this cut screw.
This is how you can easily preserve all the working properties of a bolt, stud or screw after cutting.

    Yes, yes, in Soviet times every schoolchild knew this. And in production, naturally, they used a die instead of a nut, which is what I wish for you.

        It is written very clearly, IN PRODUCTION.

    Before tightening the nut, it is a good idea to file the cut.

    But faith doesn’t allow you to remove the chamfer so that these jammed half-turns go away?

      The fact that there are no labor lessons now. The 1985 generation “P****v” is not accustomed to anything other than consuming.
      So let them watch and learn. It is for them that such advice and videos are designed.
      For example: a young professional electrician argued that 380 cannot be made into 220. Only through a transformer. I had to explain, show and teach.

    I do this: I screw 2 nuts so that the edges match, clamp them in a vice and saw off the bolt. I again clamp these nuts vertically so that the sawn-off part of the bolt ~8-10 mm sticks out from the jaws of the vice. Pressing the file against the jaws of the vice, I walk around the circle of the bolt at an angle of ~45, removing the burrs in this way and making a good approach, I unscrew the nuts. That’s it.

    In Soviet times, this was taught in labor classes.

    Since nowadays everyone uses a grinder instead of a hacksaw, you can do without a nut,
    if, after cutting the threaded part, you chamfer the side of the same disk with the foot of the grinder pressed to the floor so that sparks fly from the end to the side cut off piece, not allowing the luminous metal to float between the turns.
