64PCS Thread Repair Kit with M13 M15 M17 M20 x 1.5 Metric Sizes - Heavy-Duty Steel Leak-Proof Inserts for Oil Pan/Sump Drain Plugs (Car & Motorcycle Stripped Thread Fix)

How to Use Remove the Damaged Drain Screw: Carefully disassemble the worn or stripped oil drain screw from the sump, gearbox, or differential. Select the Right Tap: Choose a tap one size larger than the original thread. For instance, if the initial oil drain hole diameter is M14, use an M15 tap to create a new thread. Enlarge the Thread Hole: Secure the tap in a tap wrench and gradually expand the diameter of the oil drain hole, ensuring a smooth, precise fit for the new thread. Install the New Drain Plug: Slide a copper washer onto the new drain plug, then insert and tighten it into the newly tapped hole to restore a leak-proof seal.
