ZOMIYU M10 x 1.25 Metric Thread Repair Kit, 14mm One-Piece Solid 304 Stainless Steel Inserts (10 PCS), HSS Drill & Tap, Counterbore, Installation Driver, 2 Threadlockers for Stripped Internal Thread
Main highlights- 【VERIFY THE SIZE BEFORE ORDERING】This M10x1.25 Metric kit comes with 14mm inserts. Match bolt diameter, pitch, insert length, usable hole depth, and wall thickness; the drill and outer tap dimensions differ from the finished internal thread
- 【USE THE MATCHED COMPONENTS】Includes 10 solid 304 stainless inserts, 1 HSS drill bit, 1 HSS tap, 1 counterbore tool, 1 installation driver, and 2 threadlockers. Use the supplied tools and inserts together; parts from other insert systems may not interchange.
- 【Pro Tip】Apply threadlocker to screw threads before installation to prevent bushing from loosening during future removal. Over-counterboring may cause oil leakage. Check depth frequently during operation
- 【Durable Solid Steel Construction】Upgrade from flimsy wire coils! Our one-piece solid 304 stainless steel inserts provide a far more robust and permanent repair. They resist corrosion, prevent thread misalignment, and won’t unravel, offering a definitive solution for high-stress applications
- 【CONTROL THE COUNTERBORE DEPTH】The counterbore creates the recessed seat that allows the insert to finish slightly below the mating surface. A shallow cut can leave the insert proud, while excessive depth can reduce support. A tap handle is not included; confirm tool access before work
- 【CHECK THE APPLICATION FIRST】Intended for stripped internal threads in suitable aluminum, cast iron, steel, and similar components with enough surrounding material and drilling access. Verify the repair requirements for engines, transmission housings, ATV/UTV components, motorcycles, and high-precision bicycle frames
