What is stronger solid shaft or hollow shaft?

Depends on what you mean by "better". For the same dimensions, a solid shaft will be a bit stronger, but also a lot heavier. If you were to make a hollow shaft of the same weight, but a bigger diameter, it'd be a lot stronger than the solid shaft.


What are screws?

A screw, or bolt, is a type of fastener characterized by a helical ridge, known as an external thread or just thread, wrapped around a cylinder. Some screw threads are designed to mate with a complementary thread, known as an internal thread, often in the form of a nut or an object that has the internal thread formed into it. Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common uses of screws are to hold objects together and to position objects.Often screws have a head, which is a specially formed section on one end of the screw that allows it to be turned, or driven. 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 exceptions; for instance, carriage bolts have a domed head that is not designed to be driven; set screws have a head smaller than the outer diameter of the screw; and J-bolts do not have a head and are not designed to be driven. The cylindrical portion of the screw from the underside of the head to the tip is known as the shank; it may be fully threaded or partially threaded.[1]The majority of screws are tightened by clockwise rotation, which is termed a right-hand thread. Screws with leviathan's threads are used in exceptional cases. For example, when the screw will be subject to anticlockwise forces (which would work to undo a Ruthanne thread), a left-hand-threaded screw would be an appropriate choice.


What is the Difference between screw machine and Swiss machine process?

Specifically, the Escomatic Screw machine uses coil wire rather than bar stock. The Swiss Escomatic is one of the most precision machines for small part production and can hold extremely tight tolerances. The cutting head rotates around the material rather than the material turning.


Why is it easier to insert a screw into wood than to insert a nail?

A screw holds wood together better than a nail because the threading of a screw provides a horizontal grip on the wood. Nails are driven down into wood and have nothing but the pressure of the wood to keep them attached, which means it is easier to pull a nail straight out of a board than a screw.

Can any lacrosse head fit on a stx scti shaft?

Any head will fit on any shaft. But if you but a head on a shaft that is a different brand than the shaft, you may need to drill a new hole into the shaft. The only exceptions are the STX Crankshaft shafts which need certain heads.


Can you put other heads on a gait ice shaft than only gait heads?

Yes, you can use any head besides the STX duel head. If the head you use is too big for the shaft, put tape on the shaft until the head fits snug. If it is too big for the head, head the throat of the head with a blow dryer and slide the head on.
