Nuts N’ Bolts® 431


Nuts N’ Bolts® 431 is a wicking anaerobic used for preassembled equipment and structures where penetration into fastener connection points is required. This product allows very simple preventive maintenance by permitting thread locking without dismantling equipment. The product “wicks” into voids by capillary action. Use Nuts N’ Bolts® 431 to seal pores or pinhole porosity in welded seams, tanks, castings, or metal parts. The cured adhesive is a thermoset plastic suitable for temperatures up to 400ºF (204ºC), and exposure to most solvents.
