Permabond AA001130250B0101, LM113 Anaerobic Threadlocker, 250mL Bottle, Case of 4
Permabond AA001130250B0101, LM113 Anaerobic Threadlocker, 250mL Bottle, Case of 4
Permabond LM113 is a purple, low-strength anaerobic threadlocker for small metal screws, bolts and hydraulic fittings that may require disassembly. Its medium-viscosity, thixotropic formulation stays in the application area and cures between close-fitting metal parts in the absence of air. This listing supplies four 250 mL bottles, SKU AA001130250B0101.
Best Uses / Applications
- Locking small threaded metal fasteners against vibration loosening.
- Serviceable assemblies where controlled off-torque and easier disassembly are important.
- Metal hydraulic fittings suited to the grade's thread-size, gap and fluid-compatibility limits.
- Industrial assembly and maintenance using steel, cadmium, zinc and other plated fasteners.
Key Features
- Low cured strength for easy disassembly.
- Thixotropic viscosity helps prevent adhesive running away from the application area.
- Prevents vibration loosening and provides corrosion protection within the threads.
- Lubricates threads for easier assembly.
- Full cure at room temperature; no mixing required.
- Permabond's June 2026 TDS identifies the formulation as PFAS free and 100% solids.

These are typical manufacturer data, not guaranteed assembly specifications. Cure depends on substrate, gap and temperature. Copper alloys accelerate cure; oxidized or passivated surfaces such as stainless steel can slow it. Permabond identifies A905, ASC10 or heat as options for reducing cure time.
Threadlocker vs. Thread Sealant
| Selection point | LM113 threadlocker | Purpose-formulated thread sealant |
|---|---|---|
| Primary selection goal | Prevent loosening of small metal fasteners while allowing disassembly. | Prevent fluid or gas leakage through threaded pipe connections. |
| Key variables | Required off-torque, thread size, gap, substrate and cure conditions. | Joint size, gap, fluid, pressure, service temperature and required approvals. |
| Overlap | Cured material can fill thread leak paths, but application suitability must be verified. | Many anaerobic sealants also resist fitting loosening. |
| Important limit | Do not assume a universal pipe-sealing or pressure rating. | Choose the specific grade for the joint and service conditions. |
Permabond's Threadlockers vs. Thread Sealant comparison explains why locking and sealing overlap, and why formulation and joint conditions matter more than the label alone.
Application Guidance
- Use clean, dry, grease-free metal surfaces. Permabond recommends a suitable solvent-based cleaner such as acetone or isopropanol.
- Keep the bottle tip from touching metal during dispensing.
- For through holes, apply a bead across the contact length of the threads. For blind holes, apply several drops down the threads to the bottom of the hole.
- Assemble and torque as required, then allow the appropriate cure time.
- Replace the bottle lid to avoid contamination.
Handling strength is not full cure or confirmation that a fitting is ready for pressure service. LM113 is not recommended for oxygen, oxygen-rich systems or other strong oxidizers. It may adversely affect some thermoplastics; verify compatibility before use. Consult the SDS and validate the application before production.
Chemical-Resistance Reference
After 340 hours of immersion at 75°C, the TDS reports strength retention of 100% in water, butyl alcohol, hydrocarbon test fluid and JP5 jet fuel; 99% in toluene, motor oil and ethylene glycol; and 93% in JP4 jet fuel. These test conditions do not establish blanket compatibility or a pressure rating for every assembly.

Frequently Asked Questions
Is LM113 removable?
LM113 is a low-strength grade intended for small threaded fasteners and fittings that may require disassembly. Actual removal torque depends on the joint and cure conditions.
What is included in this listing?
SKU AA001130250B0101 supplies a case of four 250 mL bottles.
How long does it take to cure?
Typical handling strength is reached in 15 minutes and full strength in 24 hours on M10 steel at 23°C. Other metals, gaps and temperatures change cure speed.
What thread size and gap can it handle?
The TDS lists a maximum thread size of M20, nominally ¾ inch, and a maximum gap fill of 0.15 mm.
Can LM113 replace a pipe thread sealant?
Not automatically. Threadlockers and sealants have overlapping functions, but the joint size, gap, fluid, pressure and temperature must suit the specific grade. Verify the proposed application with Permabond.
Does it work on stainless steel?
Passivated stainless steel can slow cure. Permabond identifies A905 or ASC10 activators, or heat, as options to reduce cure time; validate the complete process for your assembly.
How should it be stored?
Store at 5–25°C and replace the lid to avoid contamination. Do not let the dispensing tip touch metal surfaces during use.
Is it suitable for oxygen systems or plastics?
It is not recommended for oxygen, oxygen-rich systems or strong oxidizers. Some thermoplastics can be adversely affected, so compatibility must be checked before use.
