Stainless Steel Types Flange Slotted Selftapping Self Tapping Thread Insert
Introduce
Self tapping inserts is a kind of fastener with internal and external thread and cutting hole or groove. There are two kinds of materials: carbon steel and stainless steel. The surface of carbon steel is galvanized (yellow zinc, color zinc and blue zinc), and stainless steel is the natural color of metal.
Feature
- Provide robust internal thread on soft substrate to meet the needs of multiple maintenance and disassembly;
- It can effectively repair the damaged internal thread;
- The self tapping sleeve is used after die casting, injection molding and other manufacturing processes, so the product structure can be simplified and the output can be increased;
- The self tapping sleeve can bear high load, so smaller inserts can be used to make the structural design of the product more compact.
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.
