- This countersunk washer is made of 304 stainless steel material, which is corrosion-resistant, durable and has good wear resistance, and is available in a full range of specifications. It has good anti-rust and anti-oxidation properties to ensure long-term indoor and outdoor applications. The cup washers provide a flush design, used under the heads of flat or oval head countersunk screws, which can hide the edges of screws to create a smooth contact surface for a clean and decorative appearance.
- The stainless finishing washers are effortless to install under the head of a screw, bolt, or nut to provide a wider load-bearing surface that supports and distributes the load, reducing the possibility of fasteners vibrating or loosening due to contact with uneven surfaces.
- When using the countersunk washer, be sure to choose the appropriate size for your application.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
