Hydraulic Bolt

Item Name Code (INC) 67769

Bolts: Federal Supply Class: FSC 5306; NATO Supply Classification Class: NSC 5306
Hardware and Abrasives: Federal Supply Group: FSG 53; NATO Supply Classification Group: NSG 53
Item Hits: 7

A fastener used for clamping a joint assembly. It is designed to be inserted and removed by hand and has sufficient clearance to avoid the risk of seizure. Using portable tool, a pre-determined hydraulic pressure is applied which stretches the bolt along its axis, leaving the nut only requiring rotation to take up the axial stretch in the bolt. On release of hydraulic pressure a high axial load is achieved.

Additional Information for Hydraulic Bolt

Hydraulic bolts are a type of bolt that is specifically designed for use in hydraulic systems. They are used to secure hydraulic components together, such as pumps, valves, and cylinders.

Hydraulic bolts are typically made from high-strength materials, such as steel, to withstand the high pressures and forces that are present in hydraulic systems. They are often coated or plated to provide corrosion resistance and improve their durability.

One of the key features of hydraulic bolts is their ability to provide a leak-free connection. They are designed with a sealing mechanism, such as an O-ring or a washer, that creates a tight seal between the bolt and the mating surface. This helps to prevent hydraulic fluid from leaking out of the system.

In addition to their sealing capabilities, hydraulic bolts also have other features that make them suitable for use in hydraulic systems. They often have a larger head size and a longer shank length compared to standard bolts, which provides increased strength and stability. They may also have a flange or a shoulder to provide additional support and prevent the bolt from loosening under high vibrations or dynamic loads.

Overall, hydraulic bolts are an essential component in hydraulic systems, as they provide a secure and leak-free connection between hydraulic components. They are designed to withstand the unique demands of hydraulic systems and ensure the reliable operation of the system.
