Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. lt 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 drain bolt, also known as an oil drain bolt, is a critical component in machinery, engines, and other mechanical systems that use oil for lubrication or cooling. It is typically located at the lowest point of an oil reservoir or sump, allowing for the controlled drainage of used or contaminated oil during maintenance or oil changes.
Key features of an oil drain bolt include:
-
Material: Often made from metals like steel, aluminum, or stainless steel to resist corrosion and provide strength under pressure.
-
Sealing Mechanism: The screw typically has an integrated sealing surface or uses an o-ring or gasket to ensure a leak-proof seal once it’s tightened.
-
Design: It may come with a hexagonal or square head to allow for tightening or loosening with a wrench. Some designs include a built-in valve or a drain hole for controlled oil release.
-
Applications: Commonly used in automotive engines, machinery, industrial equipment, or any system requiring oil lubrication or fluid containment.
-
Sizes and Thread Types: Available in various sizes and thread types to match the specific design requirements of the system.
-
Purpose: To securely close oil compartments or fluid reservoirs while preventing dirt or debris from entering. It may also be designed for easier inspection or fluid changes.
