A Counter Sunk Screw is used to be placed into countersunk holes. A counterunk is a conical hole cut into a manufactured object, or the cutter used to cut such a hole. A countersunk may also be used to remove the burr left from a drilling or tapping operation thereby improving the finish of the product and removing any hazardous sharp edges. A countersunk may be used in many tools, such as drills, drill presses, milling machines, and lathes.
A Screw, is a type of fastener characterized by a helical ridge, known as an external thread or just thread, wrapped around a cylinder. 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. 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.
Machine TypeASME standards specify a variety of Machine Screws in diameters ranging up to 0.75 inches. These fasteners are often used with nuts and they are often driven into tapped holes. In practice, they tend to be mostly available in smaller sizes and the smaller sizes are referred to as screws or less ambiguously as machine screws.
Similar to a sheet metal screw, but it has a drill-shaped point to cut through the substrate to eliminate the need for drilling a pilot hole. Designed for use in soft steel or other metals. The points are numbered from 1 through 5, the larger the number, the thicker metal it can go through without a pilot hole. A 5 point can drill a 0.5 in (13 mm) of steel, for example.
