Permabond® HM129 is a high strength medium viscosity anaerobic threadlocker and sealant. This material cures in the absence of air between tight fitting metal parts. Cure is fast and reliable on steel, cadmium, zinc and other plated fasteners. It is used for locking and sealing bolts, nuts and screws that require permanent assembly. When cured, the material prevents loosening and leakage.

*Permabond still recommends carrying out normal surface preparation to ensure consistent results. However, HM129 can provide superior performance compared with other sealing methods where there is presence of oil on surfaces.
