Self Tapping Thread Insert 302 Nut M3 - M12 For Various Materials

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.

Self-tapping screws are generally classified iron teeth, finger F is a wood-type teeth, usually countersunk head, generally refers to a type A A dental tip end banquet i.e., B-type B generally refers teeth, i.e. flat end banquet.

Parameter

Adventages

● Quick and simple installation process

● Extensive stock of METRIC, UNC, UNF inserts

● Large variety of materials and coating options

● Special lengths and diameter pitch combinations available to order

● A wide range of tooling options available

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.

Application

It is widely used in aerospace components, locomotive, high-voltage electrical appliances, automotive power, wind power, nuclear power, communication and electrical industries. It is used in aluminum, magnesium, copper alloy, plastic, plexiglass, plywood, steel, cast steel and cast iron to make it more tough and firm.
