Permatex Red Threadlocker

Permatex's high-strength Red Threadlocker is a potent solution that prevents hardware loosening, eliminating the need for costly Nylock nuts or lock washers. This adhesive-style thread treatment securely locks and seals threaded parts, guarding against vibration-induced loosening and corrosion for lasting durability. The "red" formula offers maximum strength, ideal for larger nut and bolt applications from 3/8" to 1" (10mm to 25mm). For smaller fasteners or less demanding conditions, consider using Permatex's medium-duty Blue Threadlocker.
