Loctite 2343777 Penetrating Lubricant

This 400 ml aerosol spray delivers mineral-oil-based penetrating lubricant for freeing seized fasteners and displacing moisture. It operates reliably between -38 °F and 113 °F and carries a flash point of 58 °F. The formulation contains 8 percent VOC content and is not rated for NSF certification.

Mechanics tackling rusted bolts

Technicians who need a product approved for food-processing environments should look elsewhere because this lubricant is not NSF rated. Buyers requiring a VOC-compliant formula for all 50 states will also need a different product since this one does not meet that standard.

Workshop consumable for general maintenance

The aerosol can fits standard tool-chest storage and requires no additional dispensing equipment. Its flammable Category 2 classification means it must be kept away from ignition sources during use and storage. The mineral oil base leaves a residual film that helps protect exposed metal surfaces after application.

Questions about this item

Does the Loctite 2343777 aerosol can work with standard spray nozzles, or do I need a specific attachment?

The 400 ml aerosol can uses a standard built-in nozzle; no separate attachment is required to apply the penetrating lubricant.

Can I use this mineral-oil penetrating lubricant on older fasteners that have been treated with other oils or greases?

Yes, the mineral-oil formula penetrates through existing residues on older hardware without adverse reaction.

How can I confirm the spray is performing correctly after I apply it to a seized bolt?

The lubricant should creep into threads within minutes, and the flash point of 58 Degrees F indicates normal flammability for a mineral-oil aerosol.
