Rubber Screw Hole Plugs

Don’t you just hate when you see an exposed screw or a hole from where the screw used to be? It just looks bad, doesn’t it? It’s wide open, it attracts dust, and it does not offer any kind of protection for the screw. Luckily, we have been manufacturing a solution to that problem for quite some time now. Yes, we are talking about rubber screw hole plugs – the small rubber products inserted into screw holes for a variety of reasons. In fact, these rubber plugs do not even have to plug the screw holes – they can plug any hole there is – as long as they fit nicely.

Rubber screw hole plugs are very popular products. Often used in the furniture industry, these plugs can be found in beds, chairs, divans, shelves, dressers – you name it. Also, gaming chairs. If you have ever had to assemble a gaming chair, you know that they often come with screw hole plugs so that once you’re done with the assembly and screwing everything in – you can finish it off by sealing the holes.

Unlike screw hole caps, plugs don’t cover the screw from the outside, protruding from the surface. Instead, they are inserted directly into the screw hole, creating an even tighter seal than the caps. Tight-fitting rubber screw hole plugs can create a perfect seal, keeping all the water and dust particles away from the screw, ensuring that it lasts a long time. And, seeing how rubber itself is abrasion, weather, temperature, and all other kinds of resistant – these little products can be used for both indoor and outdoor applications, across various industries and work environments.
