Choosing the right fastener for your project requires careful consideration of head style, threading type and material. There are many different types of screw heads and head shapes, each with its own benefits and uses.
The Button Head Screw
The button socket cap screw is a type of socket set screw that has a rounded button-shaped head and a hex drive. The hex drive enables them to be tightened with an allen wrench or hex key, which allows for higher torque specifications than slotted or cross recessed drive machine screws. Button head socket cap screws also provide a more visually aesthetic look than standard slotted or cross recessed drive screw types.
They are often chosen for security applications due to their tamper-proof properties, as the head cannot be unscrewed or removed. This also makes them less likely to loosen over time as compared with other types of screw.
Button head screws also offer a lower profile than cap screw styles, making them suitable for applications where the screw’s exposed head may come in contact with materials that could be damaged by a more prominent, higher-profile screw head. This includes harnesses and electrical wiring.
