A well-presented lesson on how to identify the thread, pitch, size and grade of bolts of Standard-American-Engineering and Metric, as well as their grade, is very informative. Another topic of interest would be the use of various pitches and grades. All round, an excellent presentation on the subject.
just got a job at nut/bolt supplier, trying to school myself with this new language. this video is exactly the type of information i am looking for, Thank you
Nice lesson well shared slow and accurate as we are here for the metric lesson so we can convey this for our videos to our audience with your style and abilities. The nuts was best lesson for us. Thank you, Lance & Patrick.
Thanks for the video. Very informative. I knew little now I know a lot. The metric nut strength indicators are very easy after pausing the video and realizing what they've done. It is based on the hands of 24 hour clock. So grade 10 was indicating 10 o'clock (2 hands - 1 at 10 and the other at 12). Grade 12 both marks were at 12 o'clock. Grade 14 was 12 plus 2.
Great video thanks! I’ve been having difficulty finding the nut for a ground point so I wanted to learn how the measurement system works to be able to buy a replacement, it had never clicked for me before but this was informative and not too difficult to understand. Note to others: take good pictures, bag your stuff by part of you can’t leave it in the car, and don’t take long breaks with out finishing a project.
In a metric bolt the number on the head is not considered a decimal number. Instead, it consists of two independent numbers separated by a dot. The first number indicates the bolt's tensile strength, and the last number represents the yield strength as a percentage of the tensile strength. So 10.9 means: tensile strenght= 1000 Mpa (=1000N/mm2) and it yields at 0.9x1000= 900 N/mm2. 8.8 is the base level, I have never seen anything less. 10.9 is the strongest You can get with corrosion protect coating. 12.9 is just bare steel. But I learned a lot about inch stuff. Thanks
That was really fantastic - from Australia. Where we use metric but still have a lot of older imperial nuts and bolts. Just purchased a bolt gauge because of this video.
OMG!! You are the best. I have learned so much in those 19 minutes than in other videos. You broke it down to where a child could even understand. Although I am not a child, you get the rhetoric. I need a professor like you in Construction Law. In short, your the bomb!!!!
Thank you so much for this video. I'm prepping for my mobile hydraulic certification through international fluid power society and this is really helpful for the job performance station. Can you make one on hydraulic fittings?
Loved your presentation!! Clear, concise and informative. I was waiting to see if you were going to make any mention of Whitworth. Are they determined more like the Metric or the SAE. Thoughts?
I have a string trimmer and ordered a universal brush blade kit and the nut is too large.. i am trying to find a reverse thread and find the pitch on the threaded rod to buy the right nut for it
At 6:01 in the video the bolt is supposed to be 20 TPI. However, if you count the threads I only get 11 TPI. Does the picture not reflect the actual number of threads and we are supposed to use the number you inserted (i.e., 20) instead of actually counting the number of threads there?
The spec should be M12 x 1.25 x 83 That would a a 12mm diameter bolt with a 1.25mm thread pitch and would be 83mm long. They do not make a 1.26 thread pitch unless it is a special made bolt for a specific application. If that is the case it is special and would have to be purchased as a replacement part for that specific application. Also, replacement bolts would be sold in standard lengths such as 75, 80, 85, or 90mm. You'll probably have to pick one that is close to your application.
am a tool maker the plug diameter is 13.6 and must be impreil English but i lost my thread gauge but i did not check my TPI i what to buy tape then tape 1 hole itsgoing half way .is it uif Bsf its the plug of Ford ranger petrol
