Fasteners: clips, when and how to use them?

When industry mechanics say - clamps, you immediately think about the fixing screws, as this is what is used in the workshop most often. However, there are other anaerobic fixators that can help repair a car without threads.

Bush application

There is another type of fastener that helps to a large extent in the work of a technical workshop, when fastening bushings, specific elements, such as bearings, friction linings and bushings, which are in contact with oils at high temperatures.

This type of fixatives is varnish. We can talk about several different types. Thanks to them, it is possible to avoid breakage or sudden jamming of parts leading to malfunction and costly repairs.

Unlike traditional assembly methods, these clamps can withstand heavy loads and, in addition, evenly distributing stresses. This is due to the fact that the varnishes are evenly distributed in the place of attachment, providing contact of all surfaces of the connection and fill possible gaps. This ability can prevent possible breakdowns or malfunctions.

On the other hand, its use in the repair of fastening of cylindrical elements avoids the cost of spare parts and the high cost of processing and production. It should be borne in mind that the installation of cylindrical parts requires high-precision machining, especially taking into account the load on them.

Another feature of this type of fasteners is that they have high thermal stability. As a rule, they can withstand temperatures up to 150 ° C, although there are special products that can withstand temperatures up to 230 ºC.

Advantages of using - fixing varnishes

Listed below are the main benefits of using anaerobic fixators in an automotive workshop:

• Reduce processing and installation costs.
• Increased durability
• Elimination of gaps, and displacements of an axis (for connection of cylindrical details).
• Minimize repair time.
• Improving the reliability and accuracy of installation.
• Sealing the joint and preventing possible corrosion.
• High voltage removal, installation.
• Provide more strength.
• Avoid breakage due to thermal expansion.
• Reduce the weight of the product.
• Lower processing tolerance requirements.
• Simplify product design.

Some tips for using clips

If you will use fixing varnishes, it is very important to degrease, clean and dry the area in which you will act in order to obtain greater product efficiency and to make perfect sealing. There are special detergents for this..

Fixing varnishes are products that begin to set and harden quickly in the absence of oxygen between metal surfaces, fixing and sealing. Therefore, it is very important to install quickly.

When choosing a latch for connecting fasteners with a large gap, products with high viscosity (more than 2000 MPa · s) should be used. An example of the use of this kind of product is a connection where the bearing seat or bearings were worn out and play remained. Such a landing site does not ensure alignment of the installed components. In these cases, it is important to use clamps with high adhesion strength, which will fill the gaps from wear, as a result you will get a reliable fit and a strong connection.

High quality locks

Although a wide range of products can be found on the market, we recommend some of the most suitable products for these functions that we have reviewed:

• High strength retainer, ideal for use in cylindrical bearings and bushings. It is also ideal for use on slightly oxidized surfaces that are difficult to completely clean.
• The support latch is able to fill small gaps (up to 0,25 mm) suitable for joints constantly requiring high mechanical strength and thermal stability (up to 180 ° C). Ideal for joints that need to withstand shock, bending, vibration, etc., the rapid curing of even soft metals such as aluminum, stainless steel, zinc, etc.
• A high-strength lock with the absence of a chemical risk pictogram on its packaging is the best solution in terms of safety and occupational health for the mechanic. This product is ideal for fixed mounts such as drive shafts, gearboxes, bearings, etc.
• Medium-strength latch designed for fastening worn parts with large gaps (up to 0,5 mm). Thus, it not only connects and seals, but also restores the places of cylindrical assembly, where there is strong surface wear.

Conclusion

Anaerobic varnishes and fixers are an alternative to traditional methods of mechanical assembly. These products have changed significantly and can offer unique features, much higher than mechanical fasteners. In addition, they provide flexibility and savings on workshop operations.
