About this item
- Thread Size: M12x1.75 Metric; Effective Length (After Installation): 1.5D = 18mm; Drilling Diameter (Drill diameter before tapping): 12.4mm; Material: 304 Stainless Steel; Color: Silver Tone; Packing List: 20Pcs x Wire Screw Sleeves. Crafted from 304 stainless steel, the thread insert boasts exceptional hardness, good corrosion, rust and oxidation resistance, ensuring long-lasting usage.
- Advantages: The thread repair kit has a certain elasticity and vibration resistance, which can make the load on the thread more uniform and eliminate the pitch deviation between the screw and the screw hole; the thread is deep and clear, not easy to loosen, fall off or deform, which greatly improves the strength and stability of the threaded connection and extends the service life of the equipment.
- Application: Threaded sleeves are commonly used in mechanical equipment and engineering machinery, which are the first choice for thread repair and overhaul across various industries including aviation, semiconductor equipment, automobiles, steam turbines, electronic communications, computers, lamps, molds and radiators.
- Instruction: 1. Drill a hole using the specified drill bit size. 2. Use a ST tap to create threads, ensuring the tap size matches the bolt. 3. Place the thread insert onto the installation tool and adjust the height of the tube. 4. Lightly push the insert into the hole until the end of the insert is 1/4 to 1/2 inch above the surface of the hole. 5. Use a cross-cutting tool to break off the excess insert at the marked line.
- Note: Before use, make sure the screw insert matches the threaded hole. Avoid over-tightening the screw insert during use to avoid damaging or loosening the thread.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
