Threadlocker for bolts up to one inch

J-B Weld 24236 Perma-Lock is a medium-strength blue threadlocker supplied in a 1.22 fl oz bottle. It secures threaded fasteners against vibration loosening while still allowing disassembly with hand tools. The formula suits general-purpose maintenance and assembly tasks where removable locking is required. Operating range spans 0 to 300 degrees Fahrenheit for broad environmental tolerance.

Bottle format and solvent clean-up

The liquid dispenses directly from the bottle for precise application on threads up to one inch in diameter. Excess material can be removed with solvent before full cure, simplifying rework and cleanup. Full cure is achieved in one day at room temperature, after which the bond reaches rated strength. The product complies with OSHA 29 CFR 1910.1200 hazard communication requirements.

Medium strength for removable assemblies

Medium locking strength targets fasteners that must stay tight under vibration yet be removed without heat or heavy equipment. It is not intended for permanent locking or for structural bonds requiring high-strength retention. Buyers needing permanent threadlocking or higher breakaway torque should select a different grade. Flash point is 212 degrees Fahrenheit for safe handling.

Questions about this item

Will the 1.22 fl oz bottle last through multiple maintenance cycles on 1 in fasteners?

The 36 mL bottle treats many assemblies; each application uses only a few drops on threads up to 1 in diameter.

At what temperature does the bond start to lose strength during continuous operation?

Maximum operating temperature is 300 °F; above that the medium-strength bond can degrade.

Does the cured adhesive produce fumes or require extra ventilation when equipment runs all day?

Once fully cured in 1 day it is inert; flash point is 212 °F and clean-up uses solvent only before cure.
