Properties of Loctite® Threadlocker
Loctite® threadlockers completely fill all voids between the interfacing threads, which makes the assembly an unitized component, prevents any movement between threads, and ultimately prevents loosening.
This property of Loctite® Threadlocker is especially important when assembling through-bolts in an oil reservoir or cooling jacket in order to keep the fluids sealed in and corrosion out. Examples of this application are common but not limited, to gearboxes and internal combustion engines.
The main criteria in choosing the right threadlocker out of Loctite`s wide range are the material (plastic or metal), diameter and thread length of the screws or stud bolts used, as well as their strength class. Many Loctite products are universally applicable for a range of thread sizes.
The threadlocker from Loctite functions by curing in the absence of air. Compared to mechanical locking elements, Loctite solutions have the advantage of a low cost per unit and efficient storage, supply, maintenance and repair. Product life is also extended thanks to the secure seal. Liquid threadlocker are particularly secure as the clamping force is retained, resulting in a high breakaway torque.
