BILITOOLS Oil Drain Plug Repair Kit, 84-Piece — M13–M22 Metric Taps, Replacement Plugs & Washers

If a stripped oil drain plug or rounded sump thread is causing leaks or preventing proper sealing, this kit supplies the taps, replacement plugs and sealing washers needed to restore a secure, serviceable drain. The set covers the most common metric sizes (M13, M15, M17, M20, M22) and includes both copper and aluminum crush washers so you can reseal the pan with matching hardware.

How do I know this kit fits my vehicle?

Check the OEM drain plug thread size listed in your vehicle service manual or measure the existing plug. The BILITOOLS kit contains taps and plugs for M13 x 1.25, M13 x 1.5, M15 x 1.5, M17 x 1.5, M20 x 1.5 and M22 x 1.5, covering most passenger cars and light trucks.

• Includes six taps matching common metric drain thread pitches.
• Contains 18 replacement sump plugs in assorted threads and head types.
• Provides 30 copper and 30 aluminum crush washers for proper sealing.
• Works for vehicles with tapped oil pans needing an enlarged or new thread.

What tools and steps are required to repair a stripped drain thread?

Basic hand tools plus the kit’s taps complete most repairs: a ratchet or T-handle for the tap, appropriate sockets for the new plugs, and a torque wrench to tighten to spec. Clean the pan, choose the correct tap size, chase or re-cut the damaged threads, then install a matching replacement plug and fresh washer.

• Use a thread gauge or compare plugs to identify the correct size.
• Hand-turn taps slowly and back out chips to avoid cross-threading.
• Fit a new copper/aluminum washer to the replacement plug for leak-free sealing.
• Finish by torquing the plug to manufacturer specifications.

What components are included and how do they help prevent future leaks?

The kit supplies durable taps to reshape or enlarge damaged threads, a range of replacement sump plugs that match those newly cut threads, and crush washers to create a conforming seal. Replacing worn hardware and reseating with the correct washer reduces the risk of seepage and repeated damage.

• Six high-quality taps sized for the most common metric drain threads.
• 18 replacement sump plugs to match repaired threads and head styles.
• 30 copper and 30 aluminum washers to suit different pan materials and sealing preferences.
• All parts stored in an organized case for easy selection during service.

How durable and reliable are the taps and plugs in this kit?

The taps and plugs are manufactured for workshop use and engineered to withstand multiple service operations when used properly. Using the correct tap size and proper technique helps ensure long-lasting threads and reduces the chance of repeat repairs.

• Taps designed to cut clean threads and resist wear under normal garage use.
• Replacement plugs machined for consistent fit and seating against washers.
• Copper and aluminum washers provided for reliable crush sealing across materials.
