Hernon Nuts N’ Bolts  423 is a single component anaerobic thread locking material that is particularly suitable for less active substrates such as stainless steel and plated surfaces. Nuts N’ Bolts 423 is thixotropic (becomes a liquid when stirred or shaken) and cures in the absence of air when confined between close fitting metal surfaces. Nuts N’ Bolts 423 can be used at temperatures from -65°F to 300°F. Additionally, Nuts N’ Bolts 423 develops medium strength and conforms to the requirements of ASTM D5363 (AN0321) and MIL-S-46163A (Type II Grade N).
