For years, gunsmiths have turned to Loctite for securing screws and other threaded parts on their projects. Each formula has unique features that make it perfect for various applications around the shop. Green Threadlocker (290) features a low viscosity threadlocking liquid that wicks along threads of pre-assembled fasteners. For fasteners from #2 to 1/2". Localized heat is necessary for disassembly once 290 has been applied.
This threadlocker will wick the entire length of any thread it is applied to, and due to it's low viscosity it may wick beyond the fastener to which it is applied. Take care in the use of this item, as it may cause parts to become locked together which were not intended, and it requires heat to remove.
