We connect and make motions smooth with the help of hinges. Imagine a world without them, any of the mechanical operations at our home wouldn’t be possible, especially when turning something is involved. Now you understand how important they are in our reality. Let’s dive a bit deep into the subject and grasp everything there’s present about them well. Keep reading lovely people 😊
1. Butt Hinges

- Explanation: It is a type of hinge with a pair of identical leaves and also known as a mortise hinge. Like some other types of hinges, they typically feature a larger knuckle and when the butt hinge is closed, with their wide knuckle, the two leaves will sit flush with each other.
- Working: They work like any other hinges and they make a limited angle of rotation between two objects. Whereas one leaf is connected to the rotating object and the other is connected to the fixed object. The knuckle between the two leaves helps open the rotating object by pulling it away from the fixed object. Threaded fasteners like screws are used to fix the hinges and the knuckle, probably need a pin and it may generally be fixed or it can be removable.
2. Concealed Hinges
- Explanation: Also known as cabinet hinges or cupboard hinges, and they are mainly used in every kitchen cupboard and elsewhere around the house. Invisible, hidden and European hinges- used on entry and interior doors, cabinets and furniture and they have been around for a long time.
- Full Overlay Concealed Hinges: It is used by most of the kitchen manufacturers because it completely hides/conceals the cabinet that the door end is attached to. When you look at it, it will have a straight arm and it allows the edge of the cabinet to be completely in line with the cupboard door edge. The system is fully adjustable using 3 little screws, which allows the door frame to be totally concealed and fit together snuggly and all desired angles will be finally acquirable.
- Half Overlay Concealed Hinges: It allows for a door to be mounted either side of a central carcass panel and they are very similar to the full overlay hinge. By leaving the other half exposed, the half overlay will have a bend in the arm which allows the cupboard door edge to cover half the side panel, probably seen when we compare the operation of half overlay with full overlays. They are mainly used in bedroom wardrobes and in kitchens as well.
- Inset Concealed Hinges: The hinge is visually very different and they have a large crank in the arm, which helps the cupboard door to be set inside or inset, which allows the cabinet frame showing the outer edge of the cupboard fully. You mainly see these styled hinges, only on traditional solid wood furniture because they nicely expose the wooden frame and they are also used with glass doors such as kitchen display cabinets.
- Blind Corner Hinges: This style of hinge is used when there’s only an inside fascia and no 90-degree cabinet end to fix to. To fix the mounting plant and hinge, a minimum distance of around 71 mm is required from the inside edge of the fascia.
- Bi-Fold Corner Hinge: Where the first door is attached to the cabinet inside panel with a one-hundred-and-seventy-degree hinge and the second door is attached to the first door with Bi-Fold hinge, and this style of hinge is used for double door corner cabinets. It is commonly seen in kitchen corner cabinets fitted with Carousels.
3. Continuous (Piano) Hinges

- Due to its length and is used in applications with extended dimensions. The hinge is mainly two same-sized leaves joined together by a pin and this type of hinge minimizes stress and distributes weight evenly on the component it is attached to.
- By the original purpose, the actual name comes and is to secure a piano lid to the piano itself. They are designed to cover the entire length of the operator, ranging commonly from automotives and specialty vehicles to marine.
- When the budgets are tight, these hinges are perfect because they have very low cost and they are appealing to the eyes as well. Compared to other hinges, these are highly durable too.
- They work better in high wear and tear situations reasonably due to excessive use and when the door is constantly opened and closed, it dissipates the pressure created equally. It creates a smooth and even pivot action in the overall structure along the door and panel’s length.
4. Pivot Hinges
- Explanation: It differs from other hinges because the pivot point is usually not centered but is at times actually out of the door frame or quite close to the door frame. Since it stays vertical in both positions when installed at right angles to the door, the L-shaped hinges open freely and in a more efficient manner. They are strong enough for commercial use and are usually designed for single-action doors.
- Pivot hinges are used to separate rooms or big living areas which keeps the space open and breezy, mainly in the entryways. Because of its stunning focal point which provides a seamless, contemporary entrance, it is also a popular choice for modern front doors.
- Since they are sufficiently strong enough to hold the weight with rather small frames because the glass doors, which mainly are the frameless ones, are fitted well with pivot hinges. To the innovative, modern appearance of frameless glass, the basic design of pivot hinges is indeed similar.
- Where doors are more than just functional parts, designers and architects use pivot hinges in unique installations. As an example, pivot hinges can be mainly used to mount doors that, rotate around a central or offset axis that produce a dramatic effect
5. Strap Hinges
- Explanation: It is mainly defined by its size and shape and is a mechanical hinge-based bearing. These hinges consist of the same features as other hinges and they have two leaves, a set of knuckles and a single pin. The shape is long and triangular, quite opposite of the other hinges which are short and rectangular. They are designed to use on ropes or straps and they are applicable also in gates and doors. Because they are long, they offer greater support for the structure or workpieces with which they are used.
- They are available in different lengths, like some measure 4 inches long and others measure between 6 to 12. Depending on the application, the ideal length may vary. A very common thought is, you need longer strap hinges to secure heavy workpieces and for lighter workpieces, a shorter length may suffice.
- The performance of the strap hinge may be affected by the material with which the hinge is made because it should be strong and durable for heavy applications. So that the steel strap hinges are popular among workers around the world since they have superior strength.
- In the modern world, it is easy to find strap hinges with zinc finish because the zinc protects the strap from corrosion and rusting early on. Zinc absorbs the moisture and the water particles are unable to reach the strap surface, which eventually helps in longer performance with lesser degradation in many years of time.
6. T-Hinges
- Explanation: They are designed to be fitted to ledge and brace doors and the style of the hinge helps distribute the weight of the door and prevents from putting too much strain on the actual hinge. The size of the standard internal doors, with a width between 26 to 32 inches will require an 18-inch T hinges.
- Unless the doors are really heavy, a pair of T-hinges would do fine because there’s a very little difference in strength between 12-, 15- and 18-inch hinges. Imagine you used 3 hinges for your door, the top one will be in tension, the bottom one will be in compression and the middle hinge will be mostly redundant. If the door is really heavy, go for a 4-hinge solution.
7. Double-Action Spring Hinges
- These are designed for use with a door and are spring-loaded mechanical bearings. The hinges allow a limited angle of rotation, meaning you can rotate or pull the door open and the enclosed spring will automatically close the door as well. It works mainly this way: the enclosed spring will stretch to create tension, because you opened the door; and that action reflects in the spring door hinge, it will then use this tension to pull the door back to its actual or original, closed position.
- They work by leveraging two springs, and most in the market operate that way. A typical variety has two barrels and the springs are enclosed in them. The barrels are mostly located on each side and within each barrel is a wire spring; while allowing for an omnidirectional swinging action, these springs create tension to automatically close the door.
