Steel thread inserts can effectivelyimprove screw connection, greatly improving the reliability. Used in all kinds of low strength materials, thread inserts can largely improve the wear resistance performance of screw connection, and avoid thread damage.Features:Steelthread inserts used in low strength materials such as aluminum, magnesium, 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, eliminate pitch and tooth deviation betweenscrew and screw hole, and absorb vibration, thus increasing the screw thread connection strength and fatigue resistance.It can prevent screw from getting loose,especially used for products requiring high coefficient of insurance.Easyto 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.Specification:Material: Stainless steel 304M5*0.8*1 D, 100pcs;M5*0.8*1.5 D, 100pcs;M5*0.8*2 D, 100pcs;M5*0.8*2.5 D, 100pcs;M5*0.8*3 D, 100pcs;Weight: 24g~79g / 0.8oz~2.8oz (approx.)Package list:1 set * Threaded InsertsNote:Installed length= #D means # x diameter, for example, M5*0.8*1 Dhas installed length = 1D = 1 x 5 = 5mm.
