302 Stainless Steel Nut M3 Self Tapping Thread Insert With Cutting Slot
Information
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.

Feature
1. Enhance connection strength and improve connection conditions. Low-strength materials such as aluminum and magnesium are selected for wire thread inserts, which can avoid slippage and wrong teeth, and obtain excellent connection performance.
2. Wear resistance. Used in frequently disassembled parts, it can greatly improve the service life of threads.
3. Increase the bearing surface. It is used in places where strong connection force is required and the diameter of the screw hole cannot be increased.
4. Anti-loosening. Especially used in the occasions where products such as spacecraft require a high insurance factor.
5. Easy to maintain. Install the damaged screw hole into the steel wire screw sleeve and continue to use it after repair to avoid the possibility of workpiece damage.
