National Exhibition and Convention Center(Shanghai)
2024 CHINESE HIGH-END FASTENER TECHNOLOGY FORUM

High-end fasteners are a business card of "Made in China", and the neck sticking problem of the key parts of heavy weapons in many large countries has always been the focus of attention. In recent years, the localization rate of domestic key components has been increasing and can be "top", but some high-end fasteners still rely on imports, and there is still a gap between domestic fasteners and "good use". As the industry accelerates the intelligent and digital transformation, the technical problems of high-end fasteners are put in front of enterprises again, which need to be solved urgently.

On March 20-22, the 14th Fastener Expo Shanghai will be grandly opened at the National Convention and Exhibition Center. At the same time, nearly 20 technical forums were held, including the theme exchange meeting of China High-end Fastener Technology Conference . The conference will mainly discuss the topic of fastener installation and failure, tightening installation and fastener relaxation application solutions, and the sharing of fastener application solutions in the terminal industry. 

Agenda of the meeting
March 20-22, 2024
Day 1
Day 2
Day 3

Background Information 

Currently, there are a wide variety of anti-loosening fasteners on the market. How do manufacturers promote their products? How do users choose appropriate anti-loosening fasteners? This invitational tournament comprehensively evaluates the anti-loosening fasteners by evaluating anti-loosening performance, installation convenience, reusability and other indicators of the anti-loosening fasteners, so as to provide an evaluation basis for manufacturers and users.

Participants 

A variety of products with anti-loosening capability, unlimited in form, with specifications of M10(preferred), or M16, grade 10.9; If special tooling and special assembly tools are required, please provide them together; Note: Special gaskets (with equipment) and supporting bolts (10.9 galvanized bolts) are provided by the organizer.

Test method

The anti-loosening tournament will be carried out on the closed-loop control fastener transverse vibration test machine of our center, which is in accordance with the requirements of ISO 16130-2015. The measured fasteners will be tightened on the test device to generate a certain clamping force. With the help of the testing machine, alternating transverse displacement is generated between the two metal plates that are clamped to reduce or even completely lose the clamping force. The clamping force value will be recorded continuously during the test. The slower the clamping force is reduced, the better the anti-loosening performance will be. The faster the clamping force decreases, the worse the anti-loosening performance will be.

Test condition

Installation method: The installation process shall be provided by the participants or the pre-tightening force shall be installed according to 75% guaranteed load of 10.9 bolts (75% of the yield strength of the bolts for stainless steel products). Apply oil to the bolt threads. Test plan: Constant amplitude: 0.5mm (M10), 0.8mm (M16); Vibration frequency: 12.5Hz; 1500 vibration cycles; Test temperature: room temperature. (The live broadcast test is only conducted once, and if there are any objections to the test results, another test can be conducted, with the higher value of the two test results.). Note: If the bolt breaks or bites during the test, it will be treated as an invalid test.
