Pre-Applied Processes

Inert Threadlocking

Based on the principle of prevailing torque, inert thread locking processes create fasteners with instant retention and sealing properties along with the added benefit of adjustability and reusability. Inert threadlockers are highly chemical resistant and eliminate the need for costly lock washers, cotter pins, or castellated nuts.

Reactive Threadlocking

Reactive thread locking processes apply dry to the touch chemical adhesives to internally or externally threaded fasteners. During installation the encapsulated components mix, causing a chemical reaction which locks together and seals the mating parts. In specific formulations an expansion also occurs, filling the gaps between fastener threads.

Inert Sealing Technologies

Whether sealing sheet metal, fastener threads, or under the head of fasteners, we have a process that will meet your requirements. ND pre-applied inert sealants are designed to withstand a wide range of pressures, chemical fluids and gasses and require no curing to work.

Reactive Sealing Technologies

ND pre-applied reactive sealants are designed to withstand a wide range of pressures, chemical fluids and gasses. Coated onto your fasteners at our factories, the sealants arrive dry to the touch. Once installed into a mating part, the reactive components mix, initiating a chemical reaction which cures the material.

Masking & Lubricating

A range of processes developed to prevent fastener seizing, reduce installation torque, limit material adhesion, and more. ND’s masking and lubricating processes help customers decrease assembly and disassembly time which leads to an increase in productivity. Pre-Applied fasteners are ready for use right out of the box with no curing or drying required.

Assembly Aids

Processes designed to make assembly SAFER, EASIER and FASTER by reducing application errors and worker fatigue. Depending on your needs, we can also provide auxiliary assembly of components to reduce the number of parts inventoried and minimize cost.
