Features: Steel thread inserts used in low strength materials such as aluminum, can avoid thread damage and get a good connection performance, to enhance connection strength and improve connection condition Used for parts that requires frequent removing, it can greatly improve service life and wear-resistance of screw thread Because of a certain-elasticity, thread insert can even the load distribution on each thread, eliminates pitch and tooth deviation between screw and screw hole, and absorb vibration, thus increasing the screw thread connection strength and fatigue resista It can prevent screw from getting loose,especially used for products requiring high coefficient of insurances Easy to maintenance, install a thread insert into a damage screw hole, then the screw hole can be used as normal, in order to avoid workpiece loss Notice: 1.Actual color may be slightly different from the image due to different light effect 2.Please allow 1-3cm deviation due to manual measurement Description: Material: Stainless steel 304 Size: M8(inner diameter) x 1.25(installed pitch) x 2D(installed length=2*8mm=16mm) Outer Diameter: 9.9mm(Min.); 10.1mm(Maxium.)
