How to use Loctite 221:
- For best results, clean all surfaces with a solvent. Allow it to dry.
- If using on inactive metal or curing speed is too slow, use an activator spray such as LOCTITE SF 7471 or SF 7649. Allow it to dry.
- Shake before use. Do not allow the tip to touch the surfaces during application. This will prevent the liquid from clogging in the nozzle.
- For thru holes. Apply several drops of the product onto the bolt at the nut engagement area.
- For blind holes. Apply several drops of the product down the internal threads to the bottom of the hole.
- For sealing applications. Apply a 360° bead of product to the leading threads of the male fitting. Leave the first thread free. For bigger threads: adjust product amount accordingly. Apply product on the female threads also.
- Assemble and tighten as required.
