Threaded Insert Locators

Threaded septic tank Inserts Locators are now available in five sizes! 1/4", 3/8", 1/2", 5/8" and 3/4". Polylok's new threaded septic tank inserts locator revolutionizes the installation of all plastic and metal septic tank inserts. Our inserts shear off when the casting is stripped, never leaving an exposed hole or exposed threads. Just thread the locator into the septic tank inserts, then tap the insert into the pre-drilled 3/8" hole and that's it! The hole will self seal allowing you to drill as many holes as needed without compromising form integrity.
