Stainless steel Self drilling screws have a point that acts as a drill bit and sharp cutting threads that tap the hole during installation. While are capable of drilling a hole into anything from metal to wood. This key difference is that self-drilling screws have a tip like a drill bit, so they do not need a pilot hole.
Countersunk head bolts are also called countersunk head screws, also known as flat head screws, which are a kind of construction parts. The head is a 90-degree cone, similar to common wood screws. The head has tool-tightening grooves, such as a Torx, Philips, square, slotted, pentagon, etc.
Benefits of Countersunk screws: Screws are all connectors used to connect two objects. Generally, the head of the screw will protrude from the upper part of the surface of the object to be connected, so that the surface will lose its flatness. the benefits of Countersunk head screws can be sunk under the surface to make the surface smooth, and hard objects need to drill countersunk holes at the corresponding positions of the countersunk head. In short, the countersunk head is the head of the screw that can keep the surface flat after installation
Materials: Can be stainless steel A2, Stainless steel A4, or carbon steel. The finish can be zinc plated or passivated.Normally stainless steel will be more expensive than carbon steel but rust-proof probably will be better.
