M4 Self - Tapping Thread Inserts Type Of 307 308 Stainless Steel Thread 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.
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.
