50Pcs M3 Thread Repair Kit, M3x2D Helical Insert Kit, Stainless Steel Coiled Wire Screw Thread Inserts for Restoring Damaged Wires in Steel, Iron, Aluminum

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 performance of screw connection, and avoid thread damage.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.1.Used for parts that requires frequent removing, it can greatly improve service life.2.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.3.It can prevent screw from getting loose,especially used for products requiring high coefficient of insurance.4.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: M3(inner diameter) x 2D(installed length=2x3mm=6mm)Quantity: 50pcsWeight: 80g(approx.)Package Includes:50 x Threaded Inserts1 x Installation Tool (M3)1 x Dedicated Tap (ST3)1 x Tang Breaker1 x Drill Bit

• Package Content: The package includes 50pcs M3x2D coiled wire helical screw inserts, 1pcs M3 installation tool, 1pcs ST3 dedicated tap, 1pcs tang breaker and 1pcs drill bit. Just embed helical insert kit into damaged screw hole, avoiding scrapping workpiece
• Elasticity Design: The elastic M3 thread repair kit balances load distribution of each thread and eliminates pitch or tooth pitch deviation between screw and screw hole. Helical insert kit absorbs vibration energy and improves anti fatigue of threaded connection
• Prevent Loosening: Coiled wire helical screw inserts can continuously maintain pretightening force between threads, effectively preventing screws from loosening. Coiled wire helical screw thread inserts are suitable for instruments with high safety requirements
• Wide Application: M3 thread repair kit is used in the low strength materials such as aluminum and in components that require frequent disassembly. Helical insert kit avoids thread damage and improves the connection status, extending service life of threads
• Stainless Steel: M3 thread repair kit is made of stainless steel without burrs, which reduces friction loss between screw and thread. Helical insert kit has high hardness and withstands extrusion force when screws are tightened, preventing dents in it
