THREAD LOCKERS

When it comes to thread lockers, there are books, charts, graphs, mil specs, test reports, and enough data to make your head spin. We keep it simple with a basic selection that seems to meet the needs of most of our customers. Here is what we carry and the manufacturers descriptions of applications.

Permatex Medium Strength Blue

This is an all-purpose strength threadlocker. Ideal for all nut and bolt applications ranging from ¼” thru 1” diameter. It locks and seals while preventing parts from loosening due to vibration. It also protects threads from corrosion. Removable with hand tools for easy disassembly.

Other suggested applications: machine tools, presses, pumps, compressors, mounting bolts, and gear boxes.

Permatex Permanent Strength Red

This is a permanent, high strength product that is applied to fasteners 3/8” to 1” in size. It is designed for securing parts that must withstand heavy shock, vibration, or extreme chemical or environmental conditions. Localized heating and hand tools are required to separate parts.
