Metric Hex Head Screws A Comprehensive Guide In the realm of mechanical engineering and construction, precision and reliability are paramount. One such component that plays a crucial role in ensuring the integrity of various structures is the metric hex head screw. This article aims to provide a comprehensive guide to this essential fastener, covering its definition, types, applications, and benefits. What is a Metric Hex Head Screw? A metric hex head screw, as the name suggests, is a type of screw with a hexagonal head that conforms to the metric system of measurements. It consists of a threaded shank and a head, which is designed to be driven into materials using a hexagon-shaped driver. The head of the screw is usually countersunk, meaning it has a flat surface that is flush with or slightly below the surface of the material being fastened. Types of Metric Hex Head Screws There are several types of metric hex head screws available, each with its own set of characteristics and applications. Some of the most common types include 1. Machine screws These screws are designed for general purpose applications and are typically used in wooden or plastic materials. They come in a variety of lengths and thread sizes. 2. Sheet metal screws As the name suggests, these screws are commonly used in sheet metal applications. They have a sharp point that allows them to penetrate thin sheets of metal easily. 3. Cap screws Also known as machine bolts, cap screws are designed for heavy-duty applications and are typically made from high-strength materials such as steel or stainless steel. 4. Set screws These screws are used to secure objects in place by applying pressure to a flat surface. They come in a variety of shapes and sizes, including round, square, and hexagon.
