Thread series cover designations of diameter/pitchcombinations that are measured by the number of threads per inch (TPI) applied to a single diameter
Hertz for pitch (high or low) and decibels (dB) for volume (loudness).
If you mean the pitch of a sound, that is related to its frequency. The SI unit is the Hertz.
There are many different thread forms in use today. The most common are; BPV thread API thread profile gauge Thread profile gauge API 5b thread gauges API thread gauges Pipe thread gauges API Thread Gauge Manufacturer & Supplier Ring gauge use Pipe threader Acme thread Feeler gauge set Ring gauge set threaded pipe plug step gauge NPT thread gauge Tapered pipe thread
No.. hertz relates to the frequency (pitch). The volume of a sound is measured in decibels.
its a measurement of cycles per second of sound or other waves and Hertz is the scientist who invented the scale of measurement
Standard thread are meassured in number of threads per inch (example 1/4-20) 1/4 inch dia. bolt with 20 threads per inch. Metric threads are measured in mm between thread (M8 x 1.5), an 8 MM bolt with a thread pitch of 1.5MM between threads.
A thread guide is a tool to measure the number and pitch of threads on a bolt
6mm bolt with 1.0 thread pitch
the parts of the screw are thread, pitch, and the last is bolt
Metric thread pitch is measured directly from crest to crest of the thread form. For example the distance from crest to crest of a M8 x 1.25 MM thread would be 1.25 MM. Another way to measure it would be linear travel per rotation, in which case a M8 x 1.25 MM thread would travel 1.25 MM each rotation.
I believe it is 12mmX1.75 thread pitch.
Take the bolt to a machine shop and they can tell you . if you dont have it most metric auto bolts have a 125 thread pitch but i dont know the diameter.
1/2 by 20 which is a fine thread grade 8 bolt 1.5 inches in length.
you can identify the slight different between an imperial bolt and a metric bolt by looking how fine their thread pitch looks like or feels like

All thread pitches are standard inch size thread pitches. I can't be more specific than that since I don't know exactly which bolt you are talking about. An example for you is the starter bolts are a 3/8-16 pitch, which is standard coarse thread. Most body panel bolts are either 5/16-18 or 3/8-16 pitch, once again, standard coarse thread pitches.
UNC stands for "UNIFIED BOLT THREAD COARSE" UNF stands for " UNIFIED BOLT THREAD FINE"
