Steel Self - Tapping Thread Insert M4 M5 M6 302 Type For Wood Insert
Introduction
Self-tapping threaded sleeves are also called self-tapping threaded sleeves. They are a new type of fastener that enhances the thread strength. Self-tapping threaded sleeves have tooth patterns on the inside and outside. They are embedded in softer materials such as plastic, aluminum alloy cast iron, and copper, which can form relatively High-strength internal threaded holes, self-tapping threaded sleeves (self-tapping braces) can also repair damaged internal threads.Self-tapping screw sets (self-tapping braces) 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.
Use
Self-tapping threaded inserts are self-tapping threaded inserts with slots or holes. Slotted threaded 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 very 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.
Material
The materials used in domestic self-tapping screw sleeves are generally carbon steel and stainless steel.
1. Carbon steel: 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 cast iron and other products with higher strength.
