Hinges Technical Information


Advanex can offer a wide range of hinges. This Knowledge Hub post provides more detail on our Hexatorq products.

Temperature Characteristics

Conventional spring coil hinges can, unpredictably, lose their lubrication and seize up, causing significant damage to mating parts. This can often occur in high temperature environments or where continual cycling increases the temperature within the hinge.

The Hexatorq constant torque design, utilising the modern engineered plastic resin, requires no lubrication.

In fact, tests show in elevated temperature application the Hexatorq friction hinges show a predictable drop-off in torque will then return to their pre-set values after a minimal cool down period. This unique concept causes no expense on replacing the damaged hinge or mating parts.

Durability Characteristics

The Hexatorq standard range has undergone extensive in-house life cycle trials and testing to allow confidence in its long term durability.

The combination of stainless steel and plastic resin removes the need for lubrication and creates a product incorporating seizure prevention and high durability levels.

Part Number Creation

Part Number Example: the example below consists of a KATO HEXATORQ hinge with a Torque Rating of 50 Kgf-mm, with a Bracket, Right Hand Mounting and with a Shaft Diameter of 5.0mm and 2 Holes in the Shaft.

Calculating Torque Requirements


The Suretorq range of constant torque hinges has been developed to suit a multitude of applications and provide our customers with a stock range of high quality, stainless steel, positioning hinges.

Research and development have ensured these spring hinges are smaller and thinner than the industry standard offering lightweight alternatives.

Typical products using the Suretorq range of free adjusting hinges are Notebook PCs, Digital Cameras, PDA as well as several Medical and Dental devices.

The Suretorq hinges will hold position at any angle within their working range.

The entire standard range has been fully tested and inspected to provide peace of mind as well as significant savings in development and design costs.

The ST010 – ST040 Series are supplied with left and right hand mountings.

The ST060 and ST080 Range are also available in left and right hand mounting as well as our unique bi-directional mounting.
