Stainless Steel 303 / 302 Customized M4 / M5 / M6 / M8 Self Tapping Thread Insert

Introduction

As a self-tapping threaded sleeve with slotted or perforated self-tapping threaded insert, wherein the self-tapping screw-type slotted sleeve is 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. The 307/308 type 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, but some important connection parts need to be installed due to high tensile requirements or special design. Self-tapping threaded sleeve is strictly in accordance with ISO / TS16949 quality system for production and testing of products, self-tapping screw sets almost throughout the application of metal and plastic processing industry, the products have long been used in automotive, residential and commercial vehicle engines, transmissions, air The quality of industry, rail car industry, etc. has never been questioned.

Parameter

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.

For difficult to cut materials, it has larger wall thickness, shallower but sharper external thread. The screw sleeve uses three round holes as cutting edge. The difference between 307 and 308 is the length of the insert.
