Convenient, Portable & Effective

Formulated as wax-like, semi-solid adhesives packaged in a self-feeding stick applicator, Loctite 248 Threadlocker Sticks provide robust cure even on oil-contaminated or inactive metals like stainless steel. Invented by Henkel as a revolutionary method to positively lock and seal threaded fasteners, Loctite threadlocker adhesives are used in a wide range of applications from delicate fuel injection components to heavy-duty transmission and engine assemblies. Specified by automotive OEM’s and approved for use on factory assembly lines, threadlockers work by filling the spaces between threads. The result is a secure, one-piece assembly that will not loosen under stress.

Won’t Drip, Leak or Melt! Perfect For Overhead Applications

These convenient and portable products will not leak or drip when carried in a pocket, stored in a toolbox or used in an overhead application. The sticks are designed and as easy to use as Henkel’s well-known Pritt Sticks for consumers. Loctite 506166 threadlocker sticks deliver the same proven performance as the well-known liquid Loctite threadlockers: they secure threaded assemblies, fill gaps between threads, and prevent loosening, leaks and corrosion.

Removable with Hand Tools

Loctite 506166 Medium Strength Blue Threadlocker Stick is applied to a threaded fastener and can be disassembled using hand tools. This anaerobic adhesive is typically used for machine tools, presses, pumps, compressors, mounting bolts and gear boxes that require maintenance or servicing. The product works on all metals, including passive substrates such as stainless steel, aluminum and plated surfaces. It is proven to be tolerant of minor contamination due to industrial oils, e.g., motor oils, corrosion prevention oils and cutting fluids.
