Permabond LM113 Threadlocker, 50ml Bottle

Description

Permabond LM113 Threadlocker is a medium-viscosity, low-strength thread sealant built for small fasteners such as screws, bolts, and hydraulic fittings that a technician needs to take apart again later. The thixotropic formula stays where it is applied instead of running off the threads before cure, and it sets reliably on steel, cadmium, zinc, and other plated fastener finishes.

Where Permabond LM113 Threadlocker Is Used

This grade fits assemblies where vibration loosening is a real risk but a full-strength, permanent threadlocker would make future disassembly a problem. Instrument panels, small hydraulic fittings, adjustment screws, and other fasteners that see periodic maintenance are common applications. Because the cure is low-strength by design, technicians can back the fastener out with ordinary hand tools rather than needing heat or a breaker bar to free it.

How Permabond LM113 Threadlocker Holds Up

Once cured at room temperature, the bond resists vibration loosening while keeping off-torque controlled and predictable, so removal torque does not creep up over time in service. The formula also lubricates the threads during assembly, which speeds up runs on a production line, and it adds a layer of corrosion protection between mating threads. Permabond formulates LM113 at 100 percent solids with no solvent to flash off, which supports consistent cure behavior from bottle to bottle.

Choosing Between Permabond Threadlocker Grades

Permabond offers threadlockers across a strength range, and LM113 sits at the low end specifically so a fastener can be serviced again without heat or specialty tools. A higher-strength grade makes sense on a fastener that should never be touched again, such as a structural bolt buried inside an assembly, but that same strength turns routine maintenance into a real chore on access panels, adjustment screws, and small hydraulic fittings that get opened periodically. Matching grade to service frequency, not just to fastener size, keeps a maintenance schedule realistic instead of fighting the threadlocker every time a panel comes off.
