Permatex High-Strength Red Threadlocker

Permatex high-strength red threadlocker is an OEM-specified formula that works on heavy-duty applications from 3/8 in. to 1 in. (10mm to 25mm). Especially well-suited for permanently locking studs and press fits, it adds 3,000 psi holding power to slip and press-fit assemblies. Replace your set screws and snap rings while locking them against vibration loosening with Permatex high-strength red threadlocker. It is also available in a gel formula that provides "liquid-reliability" without drips, globs, mess, or waste.
