Choosing the Right Button Head Screw For Your Application

The button head screw is a common fastener used in many applications such as furniture manufacture, steel fabrication and machine tooling. It’s low domed head and wider bearing surface allows it to be installed in materials that would snag on other higher profile screw types. It’s also designed to be easily tightened and removed for quicker production times.

While all socket screws (button, dome, and flat head) have an internal hex drive, there are different variations in their heads, materials, and finishes. These variations are all meant to provide specific advantages in different environments. For example, a brass socket screw may be more resistant to corrosion than a stainless steel one.

When choosing a screw for your application, it is important to understand the underlying standards that govern its material and mechanical properties. These are often outlined in the ASME B18.3 and DIN 7380 standards, but can also include other consensus standards such as ISO 14752.

The tensile strength and shear strength of a screw are two key factors to consider when selecting a fastener for an application. It is also important to think about the type of installation and removal process and any environmental requirements for the fastener’s use. For example, if you plan on using your fastener in an environment where there will be high vibrations or temperatures, it is important to choose a more durable screw that can withstand these conditions. button head screw
