Anaerobic adhesives, sometimes referred to as threadlockers, are one-part formulations that cure in the absence of air, filling gaps between components. Ideal for mechanical fastening, they're common for locking applications like screws, nuts, bolts, or shafts. In addition to tight bonds, they also have sealant properties and can protect bolted assemblies from liquid and gas corrosion. Ellsworth Adhesives offers a wide range of anearobic adhesives from manufacturers like Henkel Loctite, Permabond, ResinLab, and HB Fuller.
