Stainless Steel M5 M6 M8 Self Tapping Slotted Thread Sleeve Screw Threaded 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.
302 type is the most widely used in all self tapping screw sleeve products. Its two slots not only play the role of cutting, but also have a little inward locking force.
Model 303 is a thin-walled version of 302 series, which is mainly used in some plastic or light alloy that cannot have thick wall.
Feature
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.
