Countersunk screws are also called countersunk screws, also known as flat machine screws, and are a type of construction part. The head is a 90-degree cone, similar to common wood screws, with tool tightening grooves on the head, including flat, cross, hexagonal, plum blossom, pentagonal, etc.
Screws are used to connect two objects. Generally, the head of the screw protrudes above the surface of the connected object, making the surface unflat. Countersunk screws can sink under the surface to make the surface flat. Harder objects need to drill countersunk holes at the corresponding position of the countersunk head. In short, the countersunk head means that the head of the screw can keep the surface flat after installation.
Screws play the role of connecting two or more objects and are indispensable necessities in daily life or industrial manufacturing. There are countersunk bolts (with grooves) and countersunk bolts (with tenons).
