what is screw and thread locking?

Vibrations and movement of materials are detrimental to the security of connections and can lead to instabilities of threads. We at Aalberts surface technologies have developed high-performance coatings that we apply to screw connections subject to extreme stress – enabling them to resist unusually high strain. For screw locking, we have all the coatings required on the market and all licensed coatings available. Our threadlocks are used primarily in the automotive industry and the construction industry – where people and machines have to be reliably protected. We coat all kinds of connecting elements, in many different sizes and screw variations, to make them more secure and to improve sealing: screws, nuts, grub screws and special parts such as elbow fittings.

the screw locking process

The range of protective coatings for threads is as extensive as the requirements in their many fields of use. A specialist in surface treatments, we make sure that our coatings offer long-term protection teamed with maximum functionality. With this in mind, our experts from Obrigheim, Germany, are working intensively to develop innovative screw locking procedures. Apart from procedures developed in-house, we process top-of-the-line products from renowned manufacturers, such as Loctite, 3M and Precote. With the right know-how, we use tried and tested quality for efficient screw locking.

properties of screw locking

When it comes to screw locking, we use a wide range of products from world-leading brand manufacturers. They are characterized by the following properties:

  • High pressure tightness
  • Special coatings for fine threads
  • High-strength bonding with an accelerated curing process
  • Excellent temperature stability
  • Low, controlled thread friction
  • White or yellow UV markers

The majority of our screw locking adhesives comply with DIN 267-27. Applied immediately after assembly, threadlocker adhesives are particularly popular in the construction industry.

To ensure reliable screw locking, we only use high-quality premium products with convincing characteristics:

  • Gas, air and liquid tightness
  • High temperature stability
  • Immediate sealing effect
  • Suitable for repeated use
  • Excellent resistance against solvents
  • Approved by the Deutscher Verein des Gas- und Wasserfaches e.V. (DVGW, recognized standardization body for the gas and water industry)
  • Suitable for pipelines or as protection against loss

base materials suitable for screw locking

The coating is preferably applied to components made of iron and steel alloys.

fields of use of screw and thread locking

Thanks to our pre-coatings for connecting elements, we are able to implement very high quantities without compromising on quality. Our screw locking is used primarily in the automotive industry and construction sector – where reliable protection of people and machines is a fundamental prerequisite. We secure or seal all kinds of connecting elements in many sizes and thread variants:

  • Screws
  • Nuts
  • Thread pins
  • Special parts, such as elbow connections

frequently asked questions - screw locking

WHAT DISTINGUISHES THE BASIC TYPES OF THREAD LOCKING?

Plastic patch: Usually applied to the external thread in the form of powder. The patch – an oval, partially applied marking – is non-adhesive, but clamping, which is why it may be reused up to about 5 times. It is therefore suitable for components requiring adjustment. The connecting elements are ready for use immediately after patching.

Thread-locking liquid: For external and internal threads. After debonding, i.e. after breaking the connection, the threadlock will no longer be effective. This type of threadlock can be used only once. Once applied, it takes about 24 hours for the thread-locking liquid to dry. After the connecting element has been screwed in, it takes 24 hours for the threadlock to achieve its full effect.

WHAT ARE MODERN THREADLOCKERS CAPABLE OF IN THE AREA OF CONNECTION TECHNOLOGY?

Threadlockers protect the connection against the effects of vibrations and temperature fluctuations. In general, the components cannot loosen themselves. Compared to mechanical fixation techniques, this threadlocker allows for quicker assembly in production lines. Threadlockers can be adhesive, clamping and sealing at the same time. Once the screw or nut has been screwed in, it takes approx. 24 hours for the product to achieve its full effect. The actual time depends on the product used.

WHY IS SCREW LOCKING PRIMARILY SOUGHT-AFTER IN THE AUTOMOTIVE INDUSTRY AND CONSTRUCTION SECTOR?

Applied at the factory, screw locking allows for inexpensive and quick connections which, apart from keeping components from getting loose, can also have a sealing effect. What is more, it is possible to use pre-set tightening torques during assembly. The screw locking protects the connection against the effects of vibrations and temperature fluctuations. The components cannot loosen themselves.

WHAT ADVANTAGES OFFERS THREAD SEALING?

Other threadlocker types, such as teflon tape or string, must be manually wrapped around the external thread before assembly. This is a time-consuming process.

Thanks to the liquid coating applied to the threads at the factory, great time savings can be achieved during assembly. The threadlocker is always applied to the specified thread section in just the right amount, which guarantees a degree of tightness that cannot always be achieved with manually applied thread sealing.

FOR WHAT TYPES OF COMPONENT CONNECTIONS IS PROTECTION AGAINST LOSS WORTH CONSIDERING?

Especially for all component connections which are exposed to changing loads, temperature fluctuations and/or vibrations.

WHAT DOES DIN 267-27 STIPULATE?

DIN 267-27 stipulates, inter alia, the tightening and breakaway torques of threadlockers. The standard also regulates how many threads and/or what areas are to be covered by the threadlocker.

SCREW LOCKING - WHAT DOES THIS HAVE TO DO WITH SURFACE TECHNOLOGY?

Screw locking means coatings which, for example applied to a thread, prevent loosening of screws due to vibrations or even seizure or corrosion of threaded connections.
