A screw will usually have a head on one end that contains a specially formed shape that allows it to be turned, or driven, with a tool.Common tools for driving screws include screwdrivers and wrenches.The head is usually larger than the body of the screw, which keeps the screw from being driven deeper than the length of the screw and to provide a bearing surface.
There are many ways to remove the fines from sand and crushed stone. Sand screw classifiers, classifying tanks, hydrocyclones, wet screens, log washers and jigs all have their place in sand washing operations, but none of them compare to the the Ortner® Washing System. The Ortner® can handle any size material, from a very fine mason sand all the way up to the de-dusting of 3″ rocks.

The most interesting screw here, if there is such a thing, is a variable length break-off knob screw. If you do not know exactly what length screw will work, order these and break them off where you need them. A unique design allows this to be done without damaging the threads. And here is that famous break-off knob screw.
The threads of an M14-2.0 screw, which is coarse, are spaced 0.079 inches (2.0 mm). A 9/16-12 screw, which is comparable in diameter and is also coarse, has its threads spaced 0.083 inches, which are farther apart, so there will be fewer threads per unit of measure (we used an inch in the table above).
