Oil plug screw kit

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

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.

Common Applications:

• 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.
