Code of trapezoidal thread: The code of trapezoidal thread is represented by the letter "Tr" and the nominal diameter × pitch, the unit is mm. The left-hand thread needs to be marked with "LH" after the size specification, and the right-hand thread does not need to be marked. Come d...
You will need both the thread diameter and the thread pitch to determine the thread size. If you are measuring Imperial bolt thread size, you'll need to record the measurements as thread diameter followed by a hyphen, then the thread per inch measurement. For metric bold thread size, the f...
I have calculated that there is 36.5 gallons of liquid in the dissolver which includes plutonium nitrate. I intend to put the liquid into a 55 gallon (lead-lined 2 inch thick) drum measuring 43 inches in height and 31 inches in diameter. I need to know if this is safe. I am told th...

The most common cutters of this type, under 1 1/2 inches in diameter, are provided with a shank. They have teeth on the periphery and slightly concave sides to provide clearance. These cutters are used for milling semicylindrical keyways in shafts. Angle Milling Cutters The angle milling...
From there, it’s simply a matter of taking the thread pitch of the fastener and determining how many degrees of rotation are required for the fastener to be stretched the desired amount. You may have to be careful with this method if there is a soft gasket involved. (especially when ...
safely belay with. Thicker-diameter ropes can be more abrasion-resistant and often stand up better to frequent use. If you're top roping at the local crag, you'll probably want a thicker rope. If you're hiking long distances for multi-pitch climbs, you'll want a skinnier, lighter rope...
To control the light I opted for a set of Gobe screw-on ND filters for each lens. The SIGMA lenses don’t share a common front-thread diameter (the 18-35 is 77mm and the 50-100 is 82mm.). That’s not necessarily a bad thing: The NDs can stay on the lenses, when you want to...
