Button head socket cap screw have a raised dome head that is flat at the top, giving them a finished appearance. They are a low profile fastener that is ideal for tight spaces where a lower head height is desired. They also have a wider load-bearing surface than standard socket head screws and can be used in applications that require a larger area of clamping force. They can be driven with a socket wrench (hex key) or an allen wrench and can be installed and removed without damaging the head or the shaft of the screw.

They can be used in a wide variety of application and are an excellent choice where limited head space is available. They can also be used in applications that require high strength fasteners that can stand up to vibration. They are commonly used in mechanical applications such as automotive and electronics but can also be found in many other industries.

There are a few different types of button head socket cap screws. They are most often used as a replacement for a standard socket head cap screw when a low-profile or flush head is needed. They can also be used in place of a flathead screw, although this is not recommended as it may result in the screw being unnecessarily tightened and potentially loosening or falling out of the threaded hole.
