Threadlock

Our threadlock products boast a wide range of strengths and viscosities that enable use across a variety of general engineering and automotive applications. They readily meet the needs of OEM assembly, maintenance, upgrade and overhaul projects and are therefore suitable for a number of different uses.

The 3M™ Scotch-Weld™ threadlock range can be used to fill gaps between mating metal threads in order to prevent vibration loosening and also provides an excellent seal against leakage and corrosion.

Easy to apply and fluid resistant, these threadlockers can be used to replace traditional mechanical methods such as locks, washers, split pins, Nylok® nuts and wiring.

Oil Tolerant Threadlock

Our 3M oil tolerant threadlock range is suitable for general-purpose use and provides excellent vibration, corrosion and shock resistance.

Key Features

This medium-strength thixtropic compound is designed to cure and seal threaded assemblies as well as prevent vibration loosening and leakage for a wide range of applications.

It is engineered to provide different strengths, temperatures, nut/bolt sizes and is suitable for most medium and coarse-threaded screws, nuts and bolts. It is oil tolerant to help secure as-received parts and its thixotropic properties prevent run-off, dripping or migration of the adhesive product when applied on parts.

Product Use

This product is removable with hand tools and is typically used on mounting bolts and housing screws. It has a number of other uses including locking, vibration dampening, threadlocking, sealing, adhering, gluing and bonding.

Low Strength Threadlock

Our low-strength threadlock products are formulated to prevent vibration loosening and to seal against leaks through threaded components. Ideal for a number of different uses, they are also easy to disassemble and won’t cause damage.

Key Features

This low-strength thixotropic compound is frequently used with light fasteners and provides maximum vibration and shock resistance for threaded parts. Its low removal torque allows for easy disassembly and is therefore especially suitable for use on small threaded parts and on occasions where regular disassembly is envisaged.

The low strength properties of this threadlocker also means that it won’t strip the heads off screws or bolts and therefore won’t cause any damage.

Product Use

Recommended for use on softer, non-ferrous metals such as brass. Ideal for small set screws and most types of small threaded nuts, bolts, screws and hex and slot driven components including key fasteners.
