PRODUCT USER GUIDE: Selecting your finishing cup washers

A finishing washer is designed to provide a final touch to your assembly or fastening. It not only adds an aesthetic finish but also protects your screws and helps prevent injuries.
They are used by many professionals: plumbers, carpenters, electricians, mechanics… plastic cup washers are essential for clean and properly finished assembly work.
Three main types of plastic finishing washers are available on our online store: straight-edge washers, cup washers for countersunk head screws, and cup washers for flat head screws.

Advantages of a finishing washer

Finishing washers, unlike fastening washers, are not primarily intended to limit friction between the screw and the surface or prevent movement. Their purpose is to protect the surface on which the element is fastened, thus avoiding cracks caused by excessive tightening or direct contact with the screw head, especially for countersunk head screws.
Plastic washers absorb shocks and vibrations.
A nylon finishing washer also provides excellent electrical insulation and protects your screws against corrosion.

Which cup washer should you choose?

ajile offers on its online plastic hardware store the sale of plastic washers for countersunk heads or for flat heads.
Depending on your screw, you can select the cup washer that matches its dimensions (nylon washers ranging from M3 to M8).
For countersunk head screws, another range of plastic cup washers is available: straight-edge washers.
For precise and meticulous professional work, finishing washers are essential and ensure a durable assembly or fastening without risk of injury. Using a nylon cup washer guarantees better long-term resistance thanks to its anti-corrosion properties.
