Park Tool Medium Strength Threadlocker TLR-1

Threadlockers lock threaded assemblies and keep them from loosening.

Park Tool AP-1 Adhesive Primer must be used to prep all components,
fasteners and carbon fiber surfaces prior to the application of Park Tool
threadlockers or retaining compound. 
Failure to do so could result in permanently bonded parts.

• Compatible with steel and aluminum,
• oil tolerant,
• not recommended for titanium threads.

NOTE: Some painted surfaces can be sensitive to threadlockers,
retaining compounds and primers. Test first on an inconspicuous area
to see if it causes a stain or discoloration. Clean off any excess
from painted surfaces immediately.
