An oil plug screw kit is a collection of components designed to secure the oil drain plug in a vehicle’s oil pan, ensuring a leak-free seal during oil changes. Here’s an overview of its typical features and contents:

Components of an Oil Plug Screw Kit:

1. Drain Plug (Bolt)

   • The threaded screw that inserts into the oil pan’s drain hole.

   • Made from durable materials like steel, aluminum, or brass.

   • Some feature a magnetic tip to capture metal debris from the oil.

   • Head types: Hex head (standard), Allen key, or square drive for easy installation.

2. Crush Washer (Sealing Washer/Gasket)

   • A soft metal (aluminum, copper, or composite) washer that deforms slightly when tightened to create a tight seal.

   • Prevents leaks and reduces the risk of over-tightening the plug.

   • Usually single-use (should be replaced with each oil change).

3. O-Ring (Optional in Some Kits)

   • A rubber or silicone ring for additional sealing, commonly found in certain European or high-performance vehicles.

4. Spare Parts (In Some Kits)

   • Multiple washers or plugs for future oil changes.

   • Some kits include oversized plugs for repairing stripped oil pan threads.

常見應用：

• Cars, trucks, SUVs – Standard oil changes.

• Motorcycles, ATVs – Smaller plug sizes.

• Heavy machinery, marine engines – Heavy-duty or corrosion-resistant variants.

Why Use an Oil Plug Kit?

• Prevents leaks caused by worn or damaged plugs/washers.

• Protects oil pan threads from stripping due to improper sealing.

• Convenient – Includes all necessary components in one package.
