Engine oil drain plug

The oil drain screw, also known as oil plug screw, oil discharge screw or fuel tank drain screw, is a fastener used to discharge excess oil from equipment. It is usually installed on engines, gearboxes, hydraulic systems or other equipment that requires oil discharge. The main function of the oil drain screw is to conveniently discharge the used oil inside the equipment during maintenance, servicing or oil replacement.

Product Description:

Material: Oil drain screws are usually made of high-strength steel, such as carbon steel, stainless steel, etc., to ensure sufficient strength and corrosion resistance during use.

Size: Oil drain screws come in a variety of sizes to meet the needs of different equipment. Common thread specifications include M6, M8, M10, M12, etc., with different lengths as well.

Design: Oil drain screws are usually cylindrical in design, with an internal thread at one end for connection to the oil plug hole of the equipment. The other end is equipped with a hexagonal head or a head of other shapes, facilitating tightening or loosening with a wrench or socket.

Sealing Performance: Oil drain screws need to have good sealing performance to prevent oil leakage when discharging oil. Therefore, gaskets or sealing rings are usually used during installation to improve the sealing effect.

Surface Treatment: To enhance the corrosion resistance and appearance of oil drain screws, surface treatment is usually carried out, such as galvanizing, chrome plating, painting, etc.

Application Scenarios: Oil drain screws are widely used for oil discharge in various equipment such as automobiles, motorcycles, construction machinery, agricultural machinery, ships and so on.

In conclusion, the oil drain screw is an important fastener that plays a key role in the maintenance and oil replacement of equipment. When selecting an oil drain screw, the appropriate size, material and design should be chosen according to the specific needs of the equipment.
