The I shape Hexagonal nut is a standard hex nut with a larger bearing surface, providing improved load distribution. It is used with hex bolts for secure fastening.
This nut is manufactured to metric standards and is compatible with all common bolts in The part assembly.
The 1 shape hex nut is a standard hexagonal nut with a fine thread pitch, offering precise clamping and resistance to loosening.
It is commonly used in critical connections where vibration is high, ensuring the integrity of The part.
The Stainless bellows assemby(400mm) is a flexible, corrugated stainless steel tube that absorbs thermal expansion and vibration. It is 400 mm in length.
This assembly provides a durable, leak‑free connection that can withstand high temperatures and pressure, making it ideal for The part.
The Straight joint(M26/M22) is a union that connects two tubes with M26 and M22 threads. It provides a straight‑through flow path with minimal pressure drop.
Made from corrosion‑resistant steel, this joint ensures a secure, leak‑tight connection in The part.
The Angle bracket is an L‑shaped mounting support that secures tubes and hoses to the chassis. It provides a stable mounting point for the air supply lines.
Manufactured from high‑strength steel, the angle bracket ensures that all components of The part remain properly positioned.
The Flat washer is a plain circular disc that distributes load under a bolt head or nut. It prevents surface damage and ensures even clamping pressure.
Used throughout The part, the flat washer enhances joint integrity and reduces the risk of loosening.
The Washer is a general‑purpose flat ring used as a spacer or load distributor. It is available in various sizes to suit different bolt diameters.
This washer is an essential auxiliary component for The part, ensuring proper fastening and alignment.
