Screw Locking
Liquid screw locks from DREI BOND prevent unintentional, independent loosening of screws and threaded connections due to vibration and/or shock loads. Their flowability enables them to fill gaps in the threads. This creates a permanent securing of the screws in the thread and prevents the screw from rusting at the same time.
The curing (polymerization) takes place through metal contact, without oxygen contact (anaerobic).
Several product variants are available for the individual requirements of metal connections and types, screw dimensions, temperature resistance and different breakaway torques for a later necessary reopening of the screw connection.
F.A.Q.
What are the product differences for threadlockers?
Threadlockers differ in terms of their viscosity, the application temperature range and the maximum thread or gap size, as well as in their curing time, final strength and breakaway torque.
Can screw connections be reliably secured with adhesives from DREI BOND?
DREI BOND has a comprehensive portfolio of thread lockers that cover a wide range of properties. This means that an optimally suited product can be qualified for every application, ensuring reliable, permanent securing of the screw connection.
What should be considered when using adhesives to secure screws?
Before applying the thread locker, the surfaces must be free of grease and oil. In the case of passive surfaces that do not provide copper or iron ions, such as some aluminum alloys, stainless steels or coated metals, and at temperatures below 5 °C, an activator may be required to initiate or accelerate curing. As the exclusion of oxygen is a basic requirement for curing anaerobic adhesives, maximum gap bridging is a decisive product property that must be considered when selecting and using the product.
How to select the correct thread locker?
When selecting the adhesive, the maximum gap between the components, the desired disassembly capability of the connection and the resistance to temperature, pressure and media all play a role. High-strength thread lockers can only be loosened later by heat and mechanical action (e.g. using a soldering iron). In contrast, loosening a medium or low-strength thread locker is easier and can often only be carried out mechanically using simple tools. When selecting a suitable product, the requirements for the adhesive must be considered, from application to stress during the use phase to disassembly.
