The Lisle 58650 Magnetic Drain Plug Set is a five piece replacement kit designed for use with the Lisle 58850 Oil Pan Plug Rethreading Kit. Each plug features a 5/8-18 oversize thread that matches the new threads created after rethreading a damaged oil pan. The magnetic tip captures metal shavings to help protect the engine, and each plug includes a gasket to ensure a tight, leak free seal.
