CSK Slotted Screws

A CSK bolt, also known as a countersunk bolt, is a type of fastener characterized by its flat head with a conical shape that tapers down to the threaded shaft. The conical shape of the head allows it to be flush with or slightly below the surface of the material it is fastened into when fully tightened, providing a smooth and even finish.

CSK bolts are commonly used in applications where a flush or recessed fastening is desired to avoid obstruction or to create a streamlined appearance. They are often used in woodworking, metalworking, and construction projects, as well as in furniture assembly and automotive applications.

The term "CSK" stands for "countersunk," which refers to the shape of the head. These bolts may have various drive types, such as slotted, Phillips, or hexagonal, and are available in different materials and finishes to suit specific application requirements.

When using CSK bolts, it's important to ensure that the countersink hole is properly sized and shaped to accommodate the head of the bolt for a secure and flush fit.
