Hexagon Socket Button Head Screws, also known as hex head cap screws, are commonly used in mechanical applications due to their strength and versatility. Here's some information about them:
1. **Design**: These screws feature a flat top (button head) that allows for flush mounting when fully tightened. The hexagonal shape on the shank makes it easy to use with a wrench or an Allen key for tightening.
2. **Material**: They can be made from various materials including steel, stainless steel, brass, and aluminum, depending on the application's requirements. Stainless steel is often chosen for its corrosion resistance, while brass is used for its good electrical conductivity and aesthetic appeal.
3. **Thread Type**: Hexagon socket button head screws typically have a metric thread size. Common thread sizes include M4, M5, M6, M8, etc., where "M" denotes the metric system and the number indicates the nominal diameter of the screw shaft.
4. **Size and Length**: The size of the screw refers to both the diameter of the screw and the length, which can vary widely depending on the specific application. The length is usually measured from the base of the head to the end of the screw.
5. **Head Size**: The size of the head can also vary. The "button" term refers to the flat top, but this can range from very small to quite substantial, depending on the application's needs.
6. **Applications**: These screws are widely used in construction, machinery, furniture assembly, and general engineering applications where a strong, flush-mounted fastener is required. They are particularly useful when aesthetics are important, such as in furniture or decorative fixtures, because they sit flush with the surface when tightened.
7. **Head Style**: In addition to the button head style, there are also hexagon socket cap screws (with a cylindrical head), hexagon set screws (which have a flat slot for driving with a
Set Screw driver), and others like Allen head screws, which require an Allen wrench for tightening.
When selecting hexagon socket button head screws for your project, consider factors such as the material compatibility with the parts being fastened, the required level of torque for installation, and the overall aesthetic considerations of the final product.
