Button head socket cap screws combine the similar shape of a pan head with the driver of a socket head. The socket driver is ideal for low clearance applications that require a large area clamping face. Additionally, the button head's socket drive enables higher torques than a traditional phillips or slotted drives and also allows installation in tight spaces. Compared to a standard socket head cap screw, button heads have a lower and wider profile which can be useful when the clamping material is too thin to counter-bore. A button head socket cap screw's large diameter face also helps to distribute force more evenly.
