In addition to preventing oil leakage, cylinder oil seals also help to prevent contamination. Contaminants such as dirt, dust, and moisture can enter the cylinder and cause damage to the internal components. This can lead to reduced efficiency, increased maintenance costs, and a shorter lifespan for the machinery. By creating a tight seal around the cylinder shaft, oil seals help to keep contaminants out and protect the internal components from damage.

Conversely, screws require a drill or screwdriver for installation, which can slow down the process, especially in large-scale projects. However, the use of power drills can mitigate this issue, allowing for quick and efficient application of screws. Furthermore, screws can be removed and replaced without damaging the surrounding materials as much as nails, which can be an important factor in repairs or modifications.
