O processo de encabeçamento a frio é um dos novos processos para a maquinagem sob pressão com menos ou nenhum corte
metal. É um método de processamento que utiliza a deformação plástica do metal sob a ação de
forças externas e, com a ajuda de moldes, redistribui e transfere o volume de metal para formar
as peças ou os espaços em branco necessários. O processo de encabeçamento a frio é o mais adequado para a produção de
elementos de fixação, tais como cavilhas, parafusos, porcas, rebites, cavilhas, 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:
-
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.
-
-
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).
-
-
O-Ring (Optional in Some Kits)
-
A rubber or silicone ring for additional sealing, commonly found in certain European or high-performance vehicles.
-
-
Spare Parts (In Some Kits)
-
Multiple washers or plugs for future oil changes.
-
Some kits include oversized plugs for repairing stripped oil pan threads.
-
Aplicações comuns:
-
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.
