Introduction
The Screwdriver Hex Nut is a simple tool that consists of a handle and a long metal piece, i.e., a wheel and an axle, with a hexagonal edge, and is used for tightening or loosening nuts (Anderson par. 1). A typical hex nut screwdriver consists of a handle, a shank, a blade and a hexagonal tip. A sample picture of the hex nut screwdriver is shown in Figure 1 above.
Handle
The handle of a screwdriver is an ergonomic grip, which allows one to hold the tool and serves as a lever. The length of the handle depends on the size of the screwdriver, which usually is around 7 inches, is 3 7/8’’ (“Screwdrivers” Fig. 2 ). As a rule, the handle can be made of plastic, wood or a similar material. The handle is connected to the fulcrum shank of the screwdriver.
Fulcrum Shank
The fulcrum shank of a hex nut screwdriver is a metallic rod that is attached to the handle of the screwdriver and ends with a blade. Made of chrome vanadium in most cases, the shank has a cylindrical shape of a rod and may reach nearly 7 inches in its length. The length of the shank, however, varies depending on the type and purpose of the screwdriver. As far as the width of the shank is concerned, similar principles are applied to defining its value. As a rule, the length of the shank starts at 4 ¼ ‘’ and may reach the size of 6 9/16’’ (“Screwdriver Shanks” Table 1 ). In a range of cases, fulcrum shanks are detachable and can be replaced with a shank of a different size.
Blade
The blade is defined as a metal wedge that connects the hexagonal tip and the shank. Traditionally, the width of the blade ranges from 3/32’’ to ¼’’ for the screwdrivers numbered from 1 to 9. For the screwdrivers that are numbered from 10 to 24, the width of the blade ranges from 5/18’’ to ½’’ (“Screwdrivers” Fig. 2). Traditionally, the blasé is made of chrome vanadium, though the material may differ depending on the technology and the production values. The blade ends with a hexagonal tip, which has an opening in the middle.
Hexagonal Tip
The hexagonal tip is the part of a hex nut screwdriver that serves as the tool for either planting a nut into the designated area or taking it out of a specific surface. The size of the opening in the tip may range depending on the type of nut that the hex nut screwdriver was designed for. The hexagon head ranges from 3/32’’ to 3/8’’ in size (“Screw Drive Systems” Table 1). The width of the slot, in its turn, may range from 0.005’’ to 0.149’’ (“Screw Drive Systems” Table 2). The depth of the hole in the hexagon opening also varies depending on the size of the screwdriver and the function that it is supposed to fulfill. However, traditionally, the size of the specified part of the screwdriver ranges from 1 ¾ to 5 ¾ mm in diameter (“Dimensional Bolting Catalog” 9).
Conclusion
A hex nut screwdriver is a tool that has a handle, a blade and a hexagonal tip and is used of either fastening or loosening nuts. A hex nut screwdriver consists of four parts, which are the handle, the blade, the shank and the hexagonal tip. The tool can be used in the course of a construction.
