Now, it has a total of 8 new pieces that allow customers to have access to hexagonal caps that perfectly fit what they need in each occasion.

Importance of nut protection cap for nuts and bolts

Bolt protectors are an increasingly widespread product nowadays. This is because they represent a solution to protect and give a better finish to nuts and bolts. In this sense, we can say that, on the one hand, nut protection cap for nuts and bolts have an aesthetic purpose. They help to keep nuts and bolts out of sight, achieving a more attractive and subtle visual result. But it is also important to refer to the functional role of these hexagonal caps or nut protection cap. What they do is to protect the screw or nut from dust, dirt and corrosion generated by external agents such as the sun, water, among others. It is important to bear in mind that, with the passage of time, such exposure can lead to damage to the nuts and bolts. If nuts and bolts are covered by a cap, their service life is longer. This not only ensures the safety of the elements in which they are placed, but also saves money. There will be fewer replacements of nuts and bolts.

Why choose Fortaps nut protection caps for hex nuts and bolts?

Now that we have seen the importance of incorporating bolt protectors, we want to tell you about the hex caps offered by Fortaps. The first important thing to note is that these are nut protection cap for nuts and bolts compatible with DIN 933 (ISO 4017) and DIN 985 (ISO 10511) standards. ISO 4017 is the standard that specifies the characteristics of hex head millimeter bolts with thread pitches ranging from M1.6 to M64 in diameter. Also included here are grade A products with thread pitches from M1.6 to M24 diameter and with nominal lengths up to 150 mm. In order for them to play their role correctly, it is very important that the caps are of good quality and have no sharp points or damaged parts. This, in turn, helps to avoid injuries to people as a result of handling the parts. It also prevents damage to other elements that may come into contact with the nut protection cap.

In addition to complying with the standards mentioned above, it is essential to note that Fortaps nut and bolt nut protection caps are made of low density polyethylene (PELD). They are highly resistant to weathering, as well as to the chemical agents to which these products may be exposed on a daily basis. In addition, it is important to note that Fortaps manufactures the RAL range to order. The products available in stock have a delivery time of 24 hours, so that people have quick access to these elements.
