How to choose the right screw cover / nut cover?
Choosing the right screw cover or nut cover depends on several criteria. To be sure you select the right model, you need to consider both the size of the fastener, the conditions of use, and the desired aesthetic result.
Depending on the size of the screw or nut
Each nut cover is designed to match a specific size. Check the diameter (thread) of your nut or hex-head screw, or the wrench size required for your nut or hex-head screw, in order to select the right model.
Depending on the use (indoor or outdoor)
- For indoor use, prioritize aesthetics.
- For outdoor use, choose reinforced protection against weather conditions.
Depending on the desired look
White for discretion on light furniture, black for a modern contrast, grey for a neutral, all-purpose finish.

| Indoor use | Focus on aesthetics | Choose a color that matches the furniture or surface |
| Outdoor use | Exposure to rain / humidity | Choose a robust, weather-resistant plastic nut cover |

FAQ - Frequently asked questions
1. Are screw covers reusable?
Yes, in most cases. You can carefully remove a screw cover (with a thin tool or a flat screwdriver) and reposition it, as long as the material is not deformed.
2. What is the difference between a screw cover and a screw cap?
The term “screw cap” is often used as a synonym for “screw cover”. Both refer to a device that covers the screw head for aesthetic or protective reasons.
3. What is the difference between a screw cover and a nut cover?
A screw cover is designed to cover the head of a hex-head screw, while a nut cover covers a hex nut. The specifications (shape, size, wrench) are adapted to the element to be hidden.
4. How do I choose the right size of nut cover or screw cover?
Measure the diameter or thread (or the width across flats for hex screws or nuts) and choose a cover whose internal dimensions match. Referring to metric standards (M4, M6, etc.) is helpful.
5. Can you paint a screw cover or nut cover?
Yes, some plastic models can be painted with a suitable plastic paint. Lightly sand, clean the surface, use a compatible thermoplastic paint or spray paint, and let it dry thoroughly.
6. Are nut covers suitable for outdoor and humid environments?
Yes, quality plastic models (polypropylene, nylon, polyethylene) offer good resistance to moisture, corrosion and UV, depending on their formulation. Choose materials suited to outdoor conditions.
7. Do nut covers last over time?
Yes, if installed correctly and made from quality material. A well-adjusted clip fit, without excessive stress, provides long-lasting durability. It is recommended to check their condition periodically, especially in exposed areas.
8. What materials are available for screw covers and nut covers?
The most common are plastics (PP, PE, nylon), sometimes with UV additives. For special use, some models may exist in rubber or more technical materials to withstand chemical or mechanical constraints.
