The concept of screws dates back to at least 200 BC, and these bits of hardware, from custom screws and custom fastener options to micro fasteners and micro screws have been widely useful in construction projects around the world. Today’s factory workers and wood workers are making good use of screws of multiple types, which vary in length and size, screw sharpness, head size and shape, and more. Even micro plastic forming screws can be quite useful in the right applications, and these micro plastic forming screws may vary in size and shape as well. A wood worker who needs them may find them at hardware stores or in online catalogs, and searching “micro plastic forming screw set” or “micro plastic forming screws near me” can be helpful. What else is there to know about the types of screws and when such items are needed during work?
Screws as Fasteners
The standard image of a screw is a commonly known one: a thin rod of plastic or metal, with a pointed or flat end and a screw head on the other end. And of course, the helical band wrapped around the screw body. A tool may turn the s crew head when inserted, and it will apply torque that allows the screw’s coil to eat its way through material and create grip. Pressure, whether light or more substantial, will be used to press the screw into position in material, and its coil will flake away material such as wood or metal in order to make room. When a screw’s head has reached the level of the material’s surface, then the screw is fully in position and starts its work as a fastener. Unlike nails, which are smooth on their surfaces, screws are meant to be more permanent (though they often can be unscrewed if needed for some reason). Sometimes, nails are meant to act as temporary fasteners while an item’s glue is setting, and mails can be cleanly removed from wood or metal. Some nails are also used for low-pressure fastener jobs, but for items with more stress on them or more weight, screws may be better. Nails don’t have as much grip because of their smooth bodies, but screws will indeed have that grip on their bodies to handle more strenuous loads. Many pieces of furniture, for example, may have screws in them to keep everything together.
There is more than one way to make a screw, and their shape and size may reflect what sort of items they are meant to be used in or how much strain they are meant to handle. Some of the smallest screws may be used to hold together small electrical components, including fastening the access plate for a battery area. Many handheld items powered with batteries will have a tiny screw, or a few, that fasten the battery compartment lid closed. A user may simply use a tiny screwdriver to loosen those screws to open the panel, then put them back into place afterwards. Nails would not do this job well, but screws can do it.
Some screws have flat points, and they may be meant for metal that already has screw holes drilled in to it. The screw will not have to chew its way through material, so it will not even have a point on it. Such screws may be common for metal and industrial goods made in a factory, and such screws will probably stay on place once they are fastened. These screws may also be fairly short and wide, and tough enough to handle a lot of stress and strain. Some such screws may be used for building the bodies of large vehicles, such as airplanes or even ships. This idea dates back many decades, and even steam powered ships from the turn of the century had countless such screws in them.
Someone building furniture or wood items in their personal shop will often use screws that are long, thin, and pointed, designed to chew through wood and fasten themselves permanently with minimal chances of being ripped or torn free. Such screws typically require power drills to insert. If holes are already cut into the wood, though, flat point screws may be be used.
