What it is

The 4uantum Oil Resistant Threadlocker Pen (Removable) is a blue, medium-strength thread adhesive for airsoft fasteners you still want to be able to take apart. Upon curing it leaves a gripping material on the thread so screws will not shake loose over time.

Locks but lets go

The blue label indicates medium bond strength that is removable by standard hand tools, so it is ideal for parts which need to be frequently removed for tuning or maintenance. There is no need for heat to break the bond.

Oil resistant

Like the rest of the range, the formula is oil resistant and holds its grip even near the oiled and greased assemblies around a gearbox or gas system.

Clean application

The click pen packaging conveniently dispenses a perfectly sized drop for most airsoft fasteners with no sticky fingers. Wipe the tip after use. Browse more maintenance essentials in our airsoft accessories range, or book our Kent repair service for a full service.

Frequently asked questions

How is the blue version different from the red?

The blue label indicates medium bond strength that is removable with standard hand tools, whereas the red permanent version needs heat to break. Blue is for parts you revisit.

When should I use removable threadlocker?

Use it on parts which need to be frequently removed for tuning or maintenance, such as motor grip screws, stock fixings or optic mount screws you adjust often.

Do I need heat to remove it?

No. Medium-strength blue threadlocker releases with standard hand tools, so you can strip and rebuild without a soldering iron or heat gun.

Is it safe around oil and grease?

Yes. The oil-resistant formula keeps its grip even around the lubricated assemblies found inside an airsoft gearbox or near a gas system.

How much should I use per screw?

One click gives a single, correctly sized drop for most airsoft threads. Avoid pressing continuously, and wipe the tip after use to keep the applicator clean.
