M12x1.25 Metric Thread Repair Kit, 15mm One-Piece Inserts (10PCS)

- 【VERIFY THE SIZE BEFORE ORDERING】This M12x1.25 Metric kit comes with 15mm 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.
- 【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
- 【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

Select a product to estimate shipping.How do I choose the correct size?
Match the bolt diameter and thread pitch you need to restore, then confirm the insert length, usable hole depth, wall thickness, and tool access. The listed size is the finished internal thread; drilling dimensions are different.
How much hole depth and clearance do I need?
You need enough depth for drilling, tapping, the insert, and chip clearance, plus straight access for each tool. Measure the component before ordering. Blind or restricted holes may require a different repair method.
Can I use these inserts with another tap or repair system?
Use the supplied drill, tap, counterbore, driver, and inserts as a matched system. Tools or inserts from another system may use different outside threads, diameters, or seating geometry.
Does the kit include a tap handle and how is threadlocker used?
A tap handle is not included. Choose a handle that fits the supplied tap. Two threadlockers are included; apply and cure them according to the threadlocker manufacturer's directions and your application requirements.
Why is the outside diameter (OD) of the tap the same as the OD of the stainless steel insert?
The tap cuts the internal threads for the insert's mounting hole. Those threads must mate exactly with the insert's external threads, so the tap's OD must equal the insert's external thread OD to ensure proper installation and a secure fit.
