Park Tool High Strength Threadlocker TLR-2

Park Tool TLR-2 High Strength Threadlocker is a good option for securing troublesome threaded assemblies found on a bicycle, such as fasteners with poor fitment or loose tolerances. TLR-2 semi-permanently bonds threads for a secure, long-lasting fit. TLR-2 is oil tolerant and compatible with steel and aluminum threads.

NOTICE: When retaining compound or threadlocker is used on carbon fiber frames or components, adhesive primer such as Park Tool AP-1 must first be applied to all component, fastener and frame surfaces. Failure to do so could result in permanently bonded parts.

CAUTION: 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.
