50pcs Thread Repair Kit, M4 x 0.7 Stainless Steel Wire Thread Insert Combination Tool Set for Restoring Damaged Wires in Steel M4 x 2D

Description:Steel thread inserts can effectively improve 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: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 between screw 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.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.Specifications:Material: Stainless steelSize: M4(inner diameter) x 2D(installed length=2*4mm=8mm)Quantity: 50pcsWeight: 89g(approx.)Package Includes:50 x Threaded Inserts1 x Installation Tool (M4)1 x Dedicated Tap (ST4)1 x Tang Breaker1 x Drill BitNote:Please note that the main part of this product will be sent randomly, please make sure you don't mind before ordering.
