A wafer head screw, as the name suggests, has a flat, thin, and circular head, resembling a wafer. The head is usually larger than the screw's body, providing a broad bearing surface that distributes the load evenly and reduces the chances of damage to the material being fastened. The self-tapping attribute refers to the screw's ability to cut its way through the material it is inserted into, forming threads as it goes, hence the term self-tapping.

One of the primary advantages of double end threaded rods is their ability to facilitate the connection of two non-threaded components. This feature makes them particularly useful in situations where a secure, yet adjustable joint is required. For example, in construction, double end threaded rods can be used to join metal beams, allowing for flexible arrangements of structural elements without the need for additional fixtures. Their design allows for easy adjustments, making it simple to achieve the desired tension or alignment.

The 'full-threaded' part of the name implies that the entire length of the rod is threaded, from end to end. This design offers several advantages over partially threaded rods. It allows for maximum engagement with nuts or tapped holes, providing superior holding power and load distribution. Additionally, full threading provides more flexibility in adjusting the length of the assembly, as the rod can be cut to size without losing any thread engagement area.
