A button head screw is a type of socket cap screw with a raised dome and a hexagonal drive hole that accepts an Allen wrench or hex key to tighten. These screws can be used in a wide range of applications ranging from automotive repair and maintenance tasks to furniture assembly, and they are particularly popular in heavy-duty industrial work where mating parts or panels need to be secured. The rounded head and recessed hexagonal socket make these screws less susceptible to tampering or unauthorized removal, making them a reliable choice for security-related applications as well.

While the hex drive and raised head make these screws easy to install, they are not designed for light fastening applications and require higher shear strength than flat countersunk or low head screws. Additionally, the recessed head is not as easily removed as a flathead screw.

Button head screws are available in a variety of diameters and lengths to meet the needs of a wide range of applications. They are often fabricated from Stainless Steel to provide increased corrosion resistance and durability in demanding environments.

When choosing a button head screw, it is important to consider the size of your application and whether or not it will be impacted by environmental factors such as corrosion or temperature extremes. It is also important to know how a bolt or screw’s length is measured and defined, as the measurement is taken from directly under the head to the tip of the threaded end. button head screws
