Learn how metric bolts and screws are measured. I didn't understand metric bolt measurements and did some research. Find out what I learned. It's pretty simple once you know.

Pitch is not mentionned for standard only fine thread. Takes 10bmin tob now all standard pitch, 15min more to be able to determine the diam by sight. Nobody in the world needs tables , spevial rulers... Diam minus pitch gives the diam to drill. Get full metric drill set and throw away all inch crap ... Divide costs by more than two in tools, supplies, hassle, errord...

Great great content and it gets right to the point. No long, unnecessary intros etc. Love it

@HacksbyDad Год назад

Thanks! Much appreciated! 😎

One additional "good to know" is if you need to drill and tap a hole just remove the pitch lenght from the diameter and use that drill size. M6*1 use 5mm drill, M8*1,25 use 6,8mm (difficult to find 6,75mm)

It can be confusing to look at thread pitch because SAE and metric are kind of opposite each other. An SAE #10 coarse is 24, fine is 32 (bigger number) but an M6 coarse is 1.00, fine is .75 (smaller number). The difference is "threads per inch" versus "millimeters per thread". You explained the metric side very well and now I have my head screwed on straight.

Thanks! Never thought of it that way before. 😎

It's a lot easier to use a thread pitch gauge to measure pitch than trying to line the threads up with a ruler.

Thread checkers that are arranged on a plate are good for the hardware store, but on the vehicle you often can't move the bolt or nut to the wall to check pitch. A more mobile option is a string of thread checkers, which come in either metric or SAE, strung together in a wire with both female and male threads. That strategy works best if you've got a threaded opening that can't be moved. Of course you can make your own from labeled individual bolts and nuts, but assembled thread checkers aren't that expensive and it saves a couple of hours to put it all together.

@Oblimix 11 месяцев назад

Thanks, very informative. One thing to point out is that your calculations only works if you already know the thread length, and so there's no real reason to measure it at that point. Better to instead measuring how many threads are in 10mm and divide 10 with that number to get the length? Or maybe 20mm?

Not a cap screw!! Hexagon bolt.

@David-qd3ff Месяц назад

Cap screw has threads all the way to the cap. Bolt does not

Hi appreciate the video, anyway I can get that BCP meaurement chart. Notice you dont have a link for purchase. Or do i need to purchase the chart out right from you. Any help would be appreciated. John

@HacksbyDad Год назад

Thanks for pointing out the missing link. I got my BCP thread gauge from Amazon. Unfortunately, I just looked it up and it says that it is currently unavailable. Here's the affiliate link anyway... amzn.to/3rHZh9Z 😎

How to know what number to multiply it by? Like .8 x 5 / 1.25 x 4 How to know the 5 & 4?

@HacksbyDad 2 года назад

Choose a number that will result in a whole number. .8 x 5 = 4. So in 4mm, there should be 5 threads. 1.25 x 4 = 5. So in 5mm, there should be 4 threads. Hope this helps. 😎

3 mm Allen key fits m5?

@Hank_E 9 месяцев назад

On a counter sunk head and low style head yes, normal screw use 4mm allen key.

thing is, i didnt even know if i use metric or imperial, if it fits, wing it!

@deicats9561 7 месяцев назад

Why was it that the 20mm was not measured from the top of the head and the 30mm was measured from the top of the head

@HacksbyDad 7 месяцев назад

Cap screws are measured from under the heads and machine screws from the top of the heads. I showed an example of a 30mm machine screw fitting under the head of a 30mm cap screw. 😎

No. Diameter and Length is measured in MILLIMETRES, CENTIMETRES and then there are METRES. A meter is a measuring instrument.

@HacksbyDad 4 месяца назад

It is METER in the US. 😎 Where are you from?

@vladimus9749 6 месяцев назад

I love how there are all these numbers and none of them tell you which socket to use. That would actually be helpful to print in the head instead of whatever nonsense 8.8 means. 🤦
