Loctite 577 Medium Strength Threadlocker

Loctite 577 is designed for the locking and sealing of metal threaded pipes and fittings. Particularly suitable for use on stainless steel without the need for surface activation. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. - Loctite 577 provides robust curing performance. It not only works on active metals (e.g. brass, copper) but also on passive substrates such as stainless steel and plated surfaces. The thixotropic nature of Loctite 577 reduces the migration of liquid product after application to the substrate.
