It all has to do with how gases and water vapour behave in enclosed spaces, and is governed by a few Laws of Physics, such as Boyle’s, Charles’, Dalton’s & Henry’s. In essence, once water enters a space (because it is not sealed properly) instead of the water evaporating out again later, it becomes water vapour and remains in the space for a much longer time. Great product with a wide colour range and good size options, fast delivery, great price and very helpful customer service, would definately recommend giving them a try.
Snap-Caps are manufactured in Polypropylene. All materials used are 'food-grade' quality. Snap-Caps DimensionsThe Snap-Cap washer is available to suit either Countersunk screws, or for any of the ‘Flat-Bottom’ fixings (such as pan-head screws). Using the correct washer type will support your fixing properly, giving improved clamping performance and prevent the screw distorting the washer - crucial to why genuine Snap-Caps are the ONLY cover caps that COMPLETELY seal the head of the fixing. How to use Snap-Caps I have had no complaints with the Snap caps brought so far ( and that has been a few thousand). The price is good and delivery always on time with a friendly and prompt service. Ensure you are using the correct Washer type for the head of the fixing - you MUST use a CSK Washer with Countersunk-head fixings, and F/B Washer for all "flat-bottomed" fixings such as pan-heads, flange-heads etc. This effect can be easily confirmed, by examining vehicles that use hinge-caps over the number-plate fixings. Even on cars less than 6 months old, zinc-coated screws will show signs of advanced corrosion. Because they are UV-stabilised and completely seal the head of the fixing, Snap-Caps are ideal for exterior as well as interior applications. Even in extreme environments, Snap-Caps can be expected to last for 10-15 years, all the while protecting the screwhead against corrosion.
Excellent, good quality product, which are so easy to use and really finish the job off nicely. Excellent service always provided, the caps always arrive next day with out fail.
Thank you for your interest in Snap-Caps.
This was a great fast service.Staff were helpful to match up the coulours with our sinage. Lots of choose. Electrical and signalling control boxes and panels (Snap-Caps are an excellent way to insulate fasteners) A great product and next day delivery every time. We are very happy with the service from Screw caps UK. Ensure you are using the correct-sized Snap-Cap for the fixing. Some imported fixings may not conform to British or EU standards, and the heads of the fixings may be up to 40% oversized
