Flanged Step Type Hinge Shaft Nut / Bushing Nut

Core Features

Combined Nut and Bushing Function – The component combines the functions of a threaded nut for axial retention and an extended bushing for pivot support . The bushing section provides bearing support for the hinge shaft while the nut secures the assembly axially.

Integrated Flange – A circular flange is formed at the base of the nut, providing a positive stop that controls insertion depth and distributing load across the workpiece. The flange acts as a seal protecting against dust and moisture ingress .

Step Type Configuration – The bushing section features a step or shoulder that engages with the hinge or pivot component, supporting proper alignment. The step geometry provides positive positioning for consistent assembly.

Hexagon Drive Profile – The nut features standard hexagon wrenching surfaces that accept sockets or wrenches for installation . The hexagon profile allows torque application for tightening and removal.

Multi-Function Design – Supports a full range of hinge and pivot components by combining axial retention and bearing support functions into a single component .

Product Characteristics

The component is manufactured with a hexagon nut body, an integrated flange, and an extended bushing section. The bushing extends from the flange with a specified outer diameter and length that engages with the hinge or pivot component. A step or shoulder is formed on the bushing to provide positive positioning relative to the mating component.

Thread dimensions and tolerances follow standard metric or imperial thread profiles. Material composition is controlled to meet specified strength and wear resistance requirements. Carbon steel grades are available for general applications, with material selection affecting strength and durability.

Surface treatment options include zinc plating with various chromate finishes, phosphate coating, and other finishes based on corrosion resistance requirements.

Application Scenarios

Furniture Hinges and Pivot Joints – Used in furniture components where hinge shaft nuts secure pivot connections. The bushing section provides bearing support at the pivot point while the nut retains the shaft axially.

Automotive Hinge and Pivot Assemblies – Applied in vehicle door hinge systems, glove box hinges, and other pivot assemblies where combined retention and bearing support is required.

Industrial Equipment Pivots – Employed in industrial equipment, access panels, and pivot mechanisms where the component provides both shaft retention and bushing support.

Architectural Hardware – Used in door hinges, gate pivots, and building hardware where corrosion resistance and load-bearing capacity are specified.

Customization Options

Specifications and configurations can be adjusted based on application requirements. Thread sizes, bushing diameter, bushing length, flange dimensions, and overall height are customizable. Material grades include carbon steel for general applications and stainless steel for corrosion-resistant requirements. Surface treatments are selectable according to environmental exposure conditions.

Frequently Asked Questions

Q: What is the function of the bushing section on this nut?
A: The extended bushing section provides bearing support for the hinge or pivot shaft, maintaining alignment and reducing wear at the pivot point. The nut function retains the shaft axially while the bushing supports radial loads.

Q: How does the flange contribute to the component's function?
A: The flange provides a positive stop that controls installation depth and protects against dust and moisture ingress . It also distributes load across the workpiece surface.

Q: What is the difference between this component and a separate nut and bushing combination?
A: The combined design integrates axial retention and bearing support functions into a single component, reducing part count, eliminating assembly steps, and ensuring consistent alignment between the nut and bushing sections.

Q: Are these components suitable for load-bearing applications?
A: Yes. The component is designed for hinge and pivot applications where both axial retention and radial support loads are present. Material selection and dimensions should be based on the specific load requirements.

Q: What surface treatments are available?
A: Surface treatments include zinc plating, phosphate coating, and other finishes based on corrosion resistance requirements and environmental exposure conditions.

Installation Considerations

The component should be installed with the bushing section engaging the pivot component and the flange seating against the workpiece surface. The hexagon drive profile allows torque application using standard sockets or wrenches. Torque should be applied according to specified tightening procedures for the thread size and application. The step configuration provides positive positioning relative to the mating component. Thread condition should be inspected before installation; damaged threads may affect assembly integrity. For plated or coated components, coating thickness should be within specified tolerances to maintain thread fit and bushing dimensions. The flange provides dust and moisture protection at the installation interface .
