302 Series Threaded Self-Tapping Insert M14 *2.0 * 1D Wire Thread Insert

Use

Self-tapping threaded inserts are self-tapping threaded inserts with slots or holes. Slotted self-tapping threaded inserts are recommended for most applications. On some materials, this threaded sleeve provides the perfect specific thread lock function. If it still does not work, it is generally recommended to use the 307/308 type, which has made a major breakthrough in the difficulty of material cutting. This product not only has a thick wall, but also has three circular holes with cutting ability scattered on the wall. The 307/308 product is especially suitable for the case where the material thickness is not too wide.

Generally, there is no need to install self-tapping screw sleeves for products that are not required. However, some important connection parts need to be installed due to high tensile requirements or special design. Self-tapping screw sleeves are produced and tested in strict accordance with the ISO/TS16949 quality system. The application of self-tapping screw sleeves almost runs through the entire metal and plastic processing industry. The products have long been used in the automobile industry, civil and commercial vehicle engines, transmissions, and aviation. Industry, rail car industry, etc., its quality has never been questioned.

Introduce

The self-tapping thread insert installation does not need to be threaded in advance. It can be directly screwed into the specific hole reserved for the base material with the installation tool. The same screw as the original can also be used for the female thread of the broken tooth. It is economical and beautiful. For new products It can also increase the thread strength. Self-tapping thread insert are now widely used in the automotive industry, rail car industry, shipbuilding industry, household appliances, construction machinery, office machinery, electronic products, engineering plastics, high-end modular furniture, aluminum die-casting and other industries. The classification of self-tapping screws generally includes iron teeth. Wooden teeth F refers to the head type, generally countersunk heads, A generally refers to the A type teeth, which is the pointed tail teeth, and B generally refers to the B type teeth, which is the flat tail teeth.

Materials

The materials used in domestic self-tapping screw sleeves are generally carbon steel and stainless steel, and the material is 45 or 40Cr steel.

1. Carbon steel 1215: Color-plated zinc, suitable for surface carburizing heat treatment on aluminum alloy, copper alloy, plastic and other substrates with low engineering strength.

2. Stainless steel SUS303 (304, 316, 316L): suitable for surface passivation treatment on products with higher strength such as cast iron.
