Swing Bolts (Big & Small)

Key Details

  • Design and mechanism
  • A swing bolt consists of a threaded rod with an "eye" or hinge at one end and threads for a nut at the other.
  • The hinged end is permanently mounted to the tank's flange using a pin. This allows the bolt to swing freely away from the manlid opening.
  • To secure the lid, the bolt is swung into position over the manlid clamp and tightened with a hand nut. This compresses the manlid gasket to create a high-integrity, leak-proof seal.
  • Key functions and advantages
  • Rapid access: The hinged design allows for quick and easy opening and closing of the manlid, which is essential for loading, unloading, cleaning, and inspection.
  • Secure sealing: When tightened, the swing bolts apply even and consistent pressure across the manlid, ensuring a robust and reliable seal with the gasket. This is critical for preventing leaks of dangerous or contaminating cargo.
  • Reduced wear and tear: The swinging mechanism reduces friction and wear on the components compared to bolts that must be fully inserted and removed. This extends the life of both the bolts and the manlid.

Product Overview

Swing bolts are specialized, pivoting fasteners used to secure the manlid (access hatch) of an ISO tank container. Their unique design allows them to be quickly swung open for access or tightened down to create a pressure-tight seal with the manlid gasket, making them crucial for both safety and operational efficiency.
