The threaded inserts are made of high-quality stainless steel material. It forms a reliable internal thread after installation and insertion. The tail handle can be disconnected and installed at the cutout (preset disconnection point). Its tensile strength value is minimum 1400N/mm², Vickers hardness is minimum 425HV0,2, and surface finish is 2,5μm. Suzhou Renn wire thread sleeves have obvious advantages compared with traditional threads: wear resistance, high tensile strength, low thread friction, good surface quality, and excellent anti-corrosion and heat resistance.
Many soft materials, such as aluminum alloy, plastic, wood, etc., cannot reach the strength of the product's threaded holes and are very easy to damage and slip. There are also some materials that are used in very special environments and can easily cause damage to the product's threaded holes. Rust and corrosion, such as shipbuilding industry, aerospace, rail transit, etc. When the product's threaded hole encounters the above problems, the traditional approach is to re-select a larger drill bit to enlarge the hole, then tap, and finally assemble a larger screw. Such a solution is not only cumbersome but also treats the symptoms rather than the root cause. In fact, you only need to use a larger drill bit to enlarge and tap the hole, and then install a stainless steel threaded sheath inside. This solution can not only assemble the screws of the original specifications, but also avoid the need for repeated installation in later use. There is a problem with thread damage.
No matter where, stainless steel thread sheaths can be used to increase the thread strength of its products or improve the performance of threaded holes, especially in the machinery industry, automobile industry, medicine, electronics industry, aerospace and other industries, stainless steel thread sheaths All played an important role. Through thread reinforcement, the wear of the nut thread can be eliminated under normal friction. It increases the possibility of developing large-scale structural parts into lightweight and micro-structures. And by increasing the thread strength, the stability of product performance and quality is ensured.
