Wheel Stud/Nut Bolting & Residual Torque Verification

ZIPPTORK has been working for decades on the development of various assembly technologies, such as

the bolting of thread fasteners, the riveting or squeezing of solid or hollow rivets, the blind riveting of blind rivets

or rivet nuts and HUCK type bolts, etc., with an emphasis on the intelligence of the related products.

The bolting control technology is an important development target for ZIPPTORK, mainly for torque control

of thread fasteners, bolt load (clamping force) control and monitoring of bolted joint status. The portfolio brings

together key equipment such as torque testers for the calibration, verification and simulation of tool torque

capability before assembly, monitoring or controlling the tightening torque and bolt load (clamping force) during

assembly, and residual torque detection after bolted, and continuous monitoring of the bolted joint status, either

immediately or periodically, to ensure the highest reliability of the assembled equipment, all under one system

with a complete patented layout.

With the advent of the smart factory, ZIPPTORK is an essential source of technological and engineering

information to help you make Industry 4.0 a reality.

ZIPPTORK Bolting Technology

ZIPPTORK not only provides a full range of intelligent solutions for bolting operations in various industries but

also provides control of bolt load (clamping force) during the bolting process for applications that require precise

control of the clamping force of thread fasteners and monitoring the bolted joint status for abnormalities, such as

high-pressure vessels, precision transmission or transportation facilities, or high-risk equipment for nuclear power

and wind power. It also remotely monitors the bolted joint status after bolting and collecting and uploading relevant

data.

It is the best alternative to the ultrasonic bolting technology commonly used in the industry, as it can be used

with any brand and different structural designs of torque tools. Through this cost-effective solution, we can help the

industry to realise the Industry 4.0 plan and further improve the productivity and competitiveness of the industry.

Bolt Load Control Series

To meet the industrial development trend of Industry 4.0, our company has introduced a full range of patented products

related to bolt-tightening technology, which provides a cost-effective solution for the industry. Bolting of threaded fasteners is

affected by many factors, such as the softness of the material of the fasteners (bolts, nuts and washers) and the surface

roughness of the fasteners to be tightened, the influence of bruises or oil contamination on the threads during the process, and

the difference in the structure and quality of the tools used, all of which make it difficult to control accurately and effectively.

Furthermore, for the most crucial purpose of bolting works ~ the clamping force applied to the bolted joint, most of the

industry can only control the clamping pressure of the bolt load by ultrasonic sensing & bolting technology. Some applications

even require monitoring the bolted joint status after bolted and real-time notification when abnormal conditions occur. For this

purpose, ZIPPTORK has developed a series of bolt load control technologies to provide the ultimate solution for threaded

fastener tightening works, fully meeting the requirements of the Industrial Internet of Things(IIoT) applications.

Sensing Bolt & patented anti-vibration Sensing Washer for bolt load control & monitoring

It is ideal for all bolt-tightening operations requiring precise clamping force control and monitoring of the bolted joint status at

any time. The patented anti-loosening design and ease of use make it more advantageous than the conventional ultrasonic

sensing & bolting technology in mainstream applications as a great cost-effective alternative.

Patented Bolt Load Transducer

It can be used with any brand, type, or design of manual, pneumatic or electric torque tools to directly control and display the

corresponding clamping force generated on the bolted joint by the applied torque at the time and can collect relevant data. It

overturns the traditional method of controlling the bolting torque with torque tools. It directly measures the clamping force

induced in the bolted joint instead, effectively improving the quality of bolting operations. A new era of “Bolt Load Wrench” is to

come! For more product-related information and operation videos, please visit the following website - www.zipptork.com

Bolt Load Control of Threaded Fasteners

The Ultimate Solution of Bolting Technology

1. What is different from past products or current market products?

Currently, the following methods are commonly used to test the clamping force in the market:

• Ultrasonic inspection method - This inspection method is time-consuming, labor-intensive and expensive.

• Wired sensor bolt - This test method is wired, challenging to achieve wirelessly, and expensive.

• Load cell This inspection method is wired, challenging to achieve wirelessly, and expensive.

• The clamping force control is only for the sensor to connect to the PLC or other display device by wired; the layout of the bolt

load sensor of these methods is laborious and time-consuming, and the clamping force sensor does not have any anti-

loosening design and does not have the bolting sequence control function.

2. Our company has been in the field of pneumatic tools for more than 40 years and has been dedicated to research and

development of bolting technology for decades. However, in the area of bolting operation, torque control is not the most

accurate technology, but bolt load (clamping force) control is the ultimate and most precise method; since the bolt load sensor

is more expensive than the torque sensor, the market is still dominated by torque control. In recent years, customers' demand

for bolting work and data recording has been increasing, and there is an urgent demand for clamping force control in the

market. Therefore, our company has spared no effort to innovate and break through in research and development to make the

best and ultimate clamping force control and monitoring for thread fasteners.

Sensing Washer with functions of anti-loosening for controlling bolt load and monitoring the bolted joint status

The Ultimate Solution of Bolting Technology

3. Due to the difficulty in mass production of the wireless bolt load sensor, the Sensing Bolt developed by our company at the beginning is hard

to improve the yield rate and reduce the cost. With our efforts, we have finally developed a new generation of Sensing Washers to replace the

Sensing Bolts, which have the following advantages:

• The Sensing Washer is suitable for both wireless communication and wired connection.

• The wireless Sensing Washer is ideal for small magnetic field interference fields - such as the automotive industry, oil mining industry, etc.;

the wired induction spacer is suitable for large magnetic field interference fields, including the construction and bridge industry, aerospace

industry, etc.

• Low production cost and high yield rate

• Anti-loosening design (the sensing bolt itself does not have an anti-loosening plan) - this anti-loosening design is patented.

• In practice, it is easy to carry, install, and operate.

• Higher accuracy and stability than sensing bolts, with dynamic bolt load control accuracy of ±10% and static bolt load control

accuracy of±5%.

• No need to use special or custom-made bolts. Use available bolts and sensing washers to achieve the following functions:

During the bolting process:

- The bolting sequence can be controlled with our innovative controller and tag.

- Bolt load control

- Torque equivalent for reference

After bolted, combined with Industry 4.0-IoT:

- Bolted joint ( bolt load-clamping force) monitoring

- Torque equivalent display

- Clamping force, torque equivalent abnormal alarm

- Applicable tools: Any brand of manual, pneumatic and electric torque tools (static, impact, hydraulic pulse)

- Application: Construction, oil, mining, automotive, aerospace, etc., where clamping force monitoring is required.

- Applicable environment: High magnetic field interference environment, lightning strike environment...etc.

- The application can be used not only with our self-developed controller to achieve the clamping force and bolting sequence control

but also as a stand-alone device. The detailed application structure is attached.
