Cap screw
Cap Screw
A cap screw is a type of fastener used in various industries, including construction, manufacturing, and engineering. It is characterized by a cylindrical shaft with a threaded end, and a head on the other end. The head is typically hexagonal, allowing for tightening with a wrench or similar tool.
Design and Function[edit | edit source]
Cap screws are designed to fasten two parts together. They are inserted into a pre-drilled hole in the first part and then screwed into a threaded hole in the second part. The head of the cap screw remains outside the first part, allowing for easy tightening and loosening.
Cap screws are available in various sizes and materials, including steel, stainless steel, brass, and aluminum. The choice of material depends on the application and the environmental conditions to which the cap screw will be exposed.
Types of Cap Screws[edit | edit source]
There are several types of cap screws, each designed for specific applications. These include:
- Socket Cap Screws: These have a cylindrical head with a hexagonal recess for a Allen wrench. They are used in applications where there is not enough space for a standard wrench.
- Hex Cap Screws: These have a hexagonal head and are tightened with a standard wrench. They are used in construction and heavy machinery.
- Button Cap Screws: These have a rounded head that is lower profile than a hex cap screw. They are often used in furniture and cabinetry.
- Flat Cap Screws: These have a flat head that sits flush with the surface of the material. They are used in applications where a smooth surface is required.
Applications[edit | edit source]
Cap screws are used in a wide range of applications, from small electronic devices to large industrial machinery. They are commonly used in the automotive industry, in the assembly of engines and other components. In construction, they are used to secure beams, brackets, and other structural elements. In manufacturing, they are used in the assembly of machines and equipment.
