How to Properly Install Spring Clips
From a structural perspective, the elastic clip fastening system primarily consists of spring clips, helical spikes, gauge blocks, under-rail pads, plain washers, embedded sleeves, and shoulder-bearing sleepers embedded within prestressed reinforced concrete. In addition, to adjust the track height, it also includes height-adjustment shims. So, what is the installation sequence for elastic clip fasteners? We will briefly outline the installation sequence for elastic clip fasteners.

1. Household Waste: Waste stainless steel items and appliances that have been used in daily life and are now discarded (scrap materials). Most of the scrap stainless steel imported into China from Japan and South Korea falls into this category and can only be recycled as furnace feedstock. Kitchen equipment and tableware are primarily made from SUS304 and 430 steels. In the food-processing industry, the main products include food-processing machinery and containers—such as equipment for grain processing, beer and beverage production, dairy processing, and quick-freezing and refrigeration—and these typically use 304, 321, 1Cr13, and antibacterial ferritic stainless steels. 2. Industrial Waste: Scrap generated during industrial manufacturing processes, such as cut-offs and punchings.

Mercedes-Benz Recalls Seven S-Class Vehicles Due to Non-Compliant Bolt Torque
Recently, Mercedes-Benz (China) Automobile Sales Co., Ltd., in accordance with the Regulations on the Administration of Recalls of Defective Automotive Products and the Measures for the Implementation of the Regulations on the Administration of Recalls of Defective Automotive Products, filed a recall plan with the State Administration for Market Regulation. Effective immediately, the company is recalling a total of seven imported S-Class vehicles manufactured between June 6, 2018, and August 21, 2018. In vehicles within the scope of this recall, the torque of the fastening bolts for the trim panels on the A-pillar, B-pillar, and C-pillar may not meet the specified requirements. In the event of a collision that triggers the side curtain airbags, improperly installed trim panels could come into contact with the vehicle…

Why can Japan’s never-loosening nuts not be replicated even when their principle is made public?
There’s a saying that strikes a nerve among Chinese people: “Even with the principles and blueprints in hand, you still can’t make Japan’s ‘never-loosening nut’!” However, I can say with absolute confidence that if the blueprints really existed, Chinese engineers would certainly be able to produce such a nut. Many self-media outlets online, in their quest for attention, resort to sensationalist headlines that seem designed to undermine public confidence. Yet this particular nut is not only beyond the reach of Chinese manufacturers—it’s also something that even the Japanese themselves, or Germans—who likewise boast a deep-rooted manufacturing tradition—have been unable to replicate. So what exactly is the secret behind the Hardlock nut that makes it so impossible to copy? It all began when a Japanese engineer named Katsuhiko Wakabayashi attended a trade show as an employee of his company. There, he brought back several samples, one of which caught his eye: a locknut designed to prevent loosening by using a stainless-steel wire clip. The design was intricate and the price high. Drawing on the quintessential Japanese spirit of craftsmanship, Wakabayashi couldn’t stop wondering: “Couldn’t we make something simpler and cheaper?” In 1961, he finally devised a new type of locknut, which he called the “U-nut.” The U-nut’s anti-loosening mechanism relies on an elastic compression between a friction plate integrated into the nut and the threads of the bolt, effectively preventing relative rotation between the nut and bolt and thus securing the joint. Wakabayashi went on to found his own company, Fuji Precision Works, to manufacture and market this innovative nut. It quickly gained a strong foothold in the market, and Wakabayashi himself was so confident in his design that he boldly advertised it as “the nut that never loosens.” But soon after, some customers complained that the U-nut was coming loose on excavators and pile drivers. Determined to uphold his claim of “never loosening,” Wakabayashi left the company he had founded and devoted himself to finding ways to improve the design. In 1973, while passing by the Sumiyoshi Taisha Shrine near his home in Sumiyoshi Ward, Osaka, Wakabayashi looked up at the towering gate at the entrance and suddenly had an epiphany: “If we drive in a wedge, it won’t come loose!” Inspired by the principle of driving in a wedge, he then designed a structure that combined a hammer, a wedge, and the nut into a single unit.
