How to cut an electrical screw or machine screw - ultimate handyman DIY tips 

Just like many of the other commenters, I had no idea those holes were threaded! My switch cover screws were too long, and I struggled to figure out how to shorten them slightly. Turns out I had the tool in my hand the whole time! Thanks.

Brilliant. Easy when you know how. I always look at RU-vid first to find out how to do things. Saved me a journey to B&Q

Thank you. I have had several of this tools but have never even thought that they can cut screws so i have been doing it the hard way with angle grinders or hack saws, always with pretty bad results and then trying to make the end good again by grinding it on a grinding wheel. This will save me a ton of frustration! Thanks again.

This is one of the most useful videos on the internet

How did I manage before youtube? Saved me a trip to the store, and I learned something a well. Thank you!

Very excited to realize I had the right tool for this. Thanks for this video!!

Thank you. I bought 75mm which I was struggling to cut with an hacksaw you've made my life much easier

Seems I have a lo of tools I don't know how to use properly:-) Props for the tip and thanks for the series. subscribed.

Thank you so much I had no idea I actually bought this lol It worked like a charm!

Thanks for the clear instructions! I have this tool, but was clueless as to its use.

Bloody hell! thanks pal, had these all along. You are a live saver!

I actually have that tool, and had no idea it would trim screws. I'm always looking for shorties to fit bicycle fenders without reaching the tire.

Excellent. Thank you much for this information. It's hard to believe that there are other videos out there recommending you hold the screw in a pliers and cut it with a hacksaw. This makes me value the tools my grandfather gave me even more -- including the tool you used here.

Well i have a pair of these and never knew that 😳🤩🤓 thanks for the tip. Learn something new every day on your site 👍

Awesome to know. Cheers for posting

Awesome! Thanks for the training.

Such a time saver. Thanks.

Wow. Did not know this. Thank you!!

Hy, I'm a avid follower of your videos as they are the best and most understandable. Any chance at all that you could make two videos for me. ( I know I'm cheeky and monopolising your time) I'm after a video that clearly shows how to attach shelves into a van and what fixings and where to and NOT to attach to such as electric wires and fuel tank. Secondly ( sorry ha) a basic video on installing LED lights. I know you r busy but any help would be FANTASTIC. Scott from Wirral

Awesome. I’ve always used a hack saw. Great vid

Thank you, very helpful video.

Great video thanks!

Thanks for the tip. Speaking of tips, I nearly chopped off the tip of my finger using these pliers. Word to the wise, exercise caution :-)

Thanks for the tip!

thank you SO MUCH for showing me how to do this! i was outside on a ladder trying to figure out how to cut the screws shorter on an exterior led light fixture. all the insides were wired and heat shrink wrapped...but nothing ever goes easily in my DIY challenged world! tried screwing on both caps, but i knew this 2" length not only looked dorky...it was also not going to work. went into my garage brought out a ton of random nut sizes trying to get this light stable....zero, less than zero success. i even took out this "handy plastic reference measuring tool" to determine what the size & thread type were since neither the packaging, nor the instruction manuals listed the sizes of anything! errrrrr! again, useless. halloween kids were yelling "trick or treat," all animals were reminding me that it was their dinner time (dogs, pig, cat, etc.). up and down this ladder, to and from the garage, and even though i was using the same type of tool you demonstrate...it never came with instructions on what each thing does. since i was already on the ladder struggling with this light, i thought....ahhhhh it does have those holes for cutting screws, so why not try it....(try it my lazy frustrated way...cutting the screw while it was sticking out of the lamp on either side. just struggling to get it to fit in one of the various sized holes was a major pain! because as i found one that may work, i couldn't coordinate the cutting.) it was already dark (and darker because i switched the circuit off to complete this project), then it started raining and i said, "f@ck this. wondered how the heck i was going to tackle this mess. i even looked on amazon.com for a bolt cutter! endless thanks to you!!

It's easy when you know how. Thanks :)

Had one of these tools .I wonder what them holes were for, Thanks for the video

Thank you so much...

Hello This is brilliant, I have lost a headless screw. (should have finished the job I started - procrastinating Queen!) Can't find a replacement anywhere, but cutting the head off an existing screw would work, one big problem I can't find that tool anywhere, any suggestions, please? Thanks Ann B

Incredible, thank you so much! When I do this, the end of the bolt becomes very, very slightly bent-enough to make it difficult to use. Any advice?

Thanks

I don't have a pair of electrician's pliers - is there a way of cutting these using a hacksaw without damaging the thread?

Hi. Those electrician pliers look just the job, but where can I buy them?

Brill !!!

brillant

Will this work even with cheap wire strippers?

always wondered what those holes were for, and today I find out, when I needed to, who needs google web search, when you got google youtube search, thanks!

my tool is not threaded in those holes, resulting a sad crooked screw lol *sigh*

I have this tool but never knew it cuts thing like that :)....but just in my thought i dont think it can cut anything because china made it...u know what i meant

UNBELIEVABLE 🫡💯 I did not know that this tool did this 🥲🫣🫢🤭
