No. we don't make them, we don't sell them and we don't recommend them! We've been in the cover caps business for 45 years and never yet seen a hinge-style cap that works.
Firstly, the inside of the base has been made to try and work with all types of screws. Because of the different shapes of screw heads, instead these caps don't support any screws properly and the screws will tend to pull through the base of the hinge cap, distorting the walls.
When closed, the caps don't lock onto the base of the cap - made worse if the screw has diistorted the base. This means the caps can be easily removed. They can also be a swallowing risk for young children.
Because they don't close or seal properly, they allow moisture inside the head of the cap, which causes the fastener heads to rust much faster than if there was no cap there at all. You can easily see this on car number plates fitted with hinge caps. Find such a car (it might even be your own car) and pop open the cap. Even on a car just 6 months old, the screw heads will be showing signs of rust.
Instead we recommend you use Snap-Caps. They look similar (better, actually), and allow you to choose a base that matches your screw type. When fitted correctly, Snap-Caps create an airtight and watertight seal around the head of the screw - ensuring caps cannot be easily removed (esp by young children) and the screw head is protected for decades.
