Door Hinge Bolt

Function: The door hinge bolt allows the door to rotate around it, enabling the door to open and close smoothly. It bears the weight of the door and the force generated during the opening and closing process, ensuring the stability and normal operation of the door.

A door hinge bolt (also called a hinge pin or hinge screw) is a critical hardware component used to secure the hinge leaves of a door to its frame, enabling smooth rotation while providing structural stability. Typically made of durable materials like steel, brass, or stainless steel, it ensures long-term resistance to wear, corrosion, and mechanical stress.

Key Features:

Material: High-strength metals (e.g., zinc-plated steel, stainless steel) for durability.

Design: Cylindrical shaft with a threaded or smooth surface, often topped with a slotted or Phillips head for easy installation.

Function:

Aligns and connects hinge leaves.

Allows pivoting motion for door operation.

Reinforces hinge joints against sagging or misalignment.

Types:

Fixed Hinge Bolts: Permanent pins for standard hinges.

Removable Pins: Allow easy door detachment (common in security hinges).

Threaded Bolts: For adjustable or heavy-duty applications.

Applications:

Residential/commercial doors (wooden, metal, or PVC).

Cabinets, gates, and industrial machinery hinges.

Benefits:

✔ Ensures hinge integrity and door alignment.

✔ Resists shear forces and corrosion.

✔ Easy to replace or maintain.

Note: For optimal performance, hinge bolts should match the hinge size and load requirements. Regular lubrication is recommended to reduce friction.
