Our threadlockers are manufactured to provide specific viscosities, strengths, and cure speeds to meet any application requirement. These anaerobic adhesives prevent vibration loosening, while locking and sealing threaded assemblies and metal parts. They have excellent resistance to extremely harsh environments. H.B. Fuller’s threadlocker products are used in a wide range of assembly applications – from delicate electronic devices to heavy industrial equipment. They distribute the load on a fastener over the entire engagement length of the assembly, greatly reducing or completely eliminating fastener and material fatigue. They protect threaded areas by preventing rust and corrosion. These products significantly reduce production cost while enhancing the reliability of the finished product.
