The Henkel Loctite Threadlocker is an adhesive that permanently locks metal studs, bushings, and large fasteners against loosening from machine vibration. It also strengthens slip and light press fittings. This heavy-duty adhesive is designed for larger metal fasteners 3/8- to 1-inch (9.5 mm to 25 mm) in larger types of power equipment where secured fasteners are mandatory. The adhesive sets in 20 minutes and cures in 24 hours. It comes in a 6-mL tube.
