How to cut a bolt 

That trick with the crimping pliers is a superb tip. Thanks.

Nice video on workshop practice. I never thought that the lessons I received when I was aged 11 such as the correct way to use a file, how to hacksaw, cutting threads with a tap and die etc would be so very useful in 50 years time. The lack of technical teaching in schools is a crime as the lessons on metal work, woodworking etc have been more use to me in later life than any amount of poetry etc that was also taught and remains in lessons today. No wonder we have generations of men who cannot even change a fuse !.

Thganks for this. I just bought some handles for some home made cabinets and the bolts were too log. I was going to buy some new ones or pack it out with washers/ wood but the handy hint regarding the electrical crimpers was a god send. Always wobederd what those holes were for... brilliant thank you... Just saved me heaps of time and a bit of money. thanks!

As I watched you cut the bolt with a hacksaw, I was reminded of another video that indicated we should use a small amount of oil on the bolt and saw blade to lesson friction and wear on the hacksaw blade. This is important because the oil reduces friction and cools both the bolt and the blade. We know enough to put oil on the tap before beginning the threading process, but you should also have put some on the drill bit that you drilled the hole with, then a few drops down into that hole before you begin tapping it. Any time you have metal-on-metal contact, a small amount of oil or cutting grease should be added before starting to lessen the amount of frictional wear on the tool. You wouldn't knowingly start an engine without making sure there was oil in the in the crankcase, owing to the amount of wear that would occur because it was run dry. A hacksaw blade becomes dull not so much from the act of cutting, but because it is operated in a dry state.

thanks for sharing this, very helpful!

I normally add a drop of 3 in 1 oil or wd40 on the hacksaw blade when I cut bolts, it just makes the blade screech less and makes it easier to cut. Never knew you could cut bolts with crimpers though!

The cutting gets easier if you use two nuts. Lock the nuts together by the cut, and use the outer one as support for your hacksaw-blade.

Great tips, thanks again. Learn something new everyday.

WOW! I thought those electrical anti-wire-stripping pliers were only for making electrical jobs more difficult. I've discovered they're actually worth a SH*& for something now! Thank you very much!

You are extremely talented, that you for making all of these videos for us to learn from

Thanks so much, needed to cut down some 6-32 30mm screws that were too long for intended use, and using the crimp pliers to cut them worked perfectly!

I like adding a drop of 3 in 1 oil on the cut line and on the blade, it makes it easier to cut and it screeches less. Didn't know you could do that with crimpers.

You are the Champion my Friend!

Thanks. Great trick leaving the nut on first.

Thanks dude! Helped me figure out how to cut and not screw up threads.. I’ll grab a nut tomorrow. You get an A+ from me.

This was much simpler than I thought, thanks. I knew how to use the wire cutters but even my bolt cutters were too small for an m10

Magic tip with the crimping tool! 👍

Many thanks for another great and useful video.

Excellent advice - very helpful thanks

It's easier to file at 45deg against the radius of the end of the bolt rather than flat against the cut end. That will remove burrs and give a factory finished tapered end with a clean thread. Easier to get nuts on and less chance of cross threading.

Nicely demonstrated - thanks

Very helpful video!

Thanks for the tips.

I prefer to get the correct length in the first place. Good video there mate.

Great video...thanks!

Thx for the video made my job easier..

thank you for your video

Nice tips

Such a wonderful video. Thank you for sharing! #thumbsup

Brilliance, thanks!

Thanks for the video. Really helpful. I need to fabricate a part of a hinge for a Dometic refrigerator. It's threaded in the middle for 2 locking nuts (and a plate) with pins on either end. I'm going to use your hacksaw method to cut the length of a bolt. Do you have any suggestions on how to remove the threads to make a "relatively" smooth pin on either end? I was thinking about starting with a grinder and finishing it off with a metal file. Thank you for any suggestions you can give me.

Useful advice

I never knew about cutting small bolts with the wire stripper/crimper. Thats new to me. Curious if that is really what its made to do? Talking about the holes you used....

Thanks about the idea of putting the nut in and on why, and with the leftover chopped bolt piece could be used an extra nut insert a bit and arc weld it together.

Put the nut on the bolt at the length you desire. Place the head of the screw and the nut in the wise. It is now secured firmly, and when you saw along with the side of nut. You will get a straight cut, and not damage the threads should the hacksaw jump.

Thanks!

Sorry i ment the crimping pliers u used. Can they cut nuts ? I have a nut stuck on a bolt in my car. It can be seen but i can feep the nut with my hand. Its a 13mm nut, but the threads are damaged. So i was think to cut it ? Thanks

So much i never knew :)

great video,i knew those crimping pliers were good for something (as they do such a poor job actually crimping) just weren't sure what that thing was...

helpful, thanks

That's what it is for m5 or ect.i was wondering what is that for? Thank you

Do a video on cutting Grade 10.9 automotive bolts

If I were a woman, I'd marry him in a heartbeat!! Extremely useful video :)

What brand/type of hacksaw is that?

I can't believe nobody has made a dedicated tool for cutting bolts yet. There should be something like the crimper but a bit chunkier and with a longer handle so it can cut bigger bolts as well. I've been looking for it everywhere but I can't find it.

This is why Dremels were invented.

Already cut my bolt without putting the nut on :( Tips on how to thread the nut on?

Place the hacksaw in the vice place the bolt in an electric drill position bolt over the hacksaw on the mark, start the drill GENTLY lower and hey presto!

Do you use a mill file

Right on

Thanks

After the cut I make a little champfer on the edge of the threading ,it's more beautiful and it makes easier to screw the bolt into a nut.

I've NEVER noticed those holes on my cheap wire strippers before! Could have totally used them to cut some plug socket screws I needed to shorten the other day. Instead I pissed about with the junior hacksaw and file! Nice one.

The best way to cut a bolt is, just put the bolt in the drill machine and start it then just light press the saw blade from where you need to cut bolt, the drill will rotate the bolt and blade will cut deeper and deeper into the bolt and finally cut it without damaging the thread.

An interesting video was on the Discovery Channel or History Channel they installed a roof on a stadium the screws they install were too long they cut the screws and took the temper out of the screws roof fell in three years later who would ever think that could happen after the fact it's easy to see it

Dang i chucked my pair of pliers as they were crap crimpers lol

how to cut the thread

Now that’s what I’m talking aboooot.

I prefer to melt down the screws / bolts and recast them in my forge to the proper length. /heh

If you cut 1/2way through with a hack saw then wiggle the cut end off the nut will start no problem.

Or you just cut as a normal person, and use a grinder to finish the edges off...

That's a thick bolt face it down and face it left. So terrible
