Button Head Socket Cap Screw are threaded fasteners with a rounded button-shaped head that is countersunk into a surface and can be tightened using an allen wrench (hex key). They feature a wider bearing surface than traditional socket cap screws and a clean appearance. They are used in a variety of applications including machinery, automotive and electronics.
The main difference between cap screws and button head caps is strength requirements. Cap screws have a higher tensile strength rating than button heads and are better suited for applications where strength is more important. Cap screws also have a thicker side wall and deep hex recess that allows them to achieve higher preload ratings than socket head caps.
Both types of fasteners are available in a variety of lengths and materials to suit a range of applications, from light duty to high tensile. They are typically made of materials like stainless steel that provide excellent corrosion resistance and durability.
When choosing the right fastener for your project, it’s important to consider factors like length, material, head style and drive type. Different types of screws are better suited for different applications, depending on the type of load the fastener is required to bear and the aesthetics of the finished product. For instance, a flat head screw has a low profile that is countersunk into the work surface, which minimizes their protrusion and eliminates the risk of them catching clothing or a tool when moving equipment.
