Thread Repair Inserts NEO tools M12, kit 10 pcs (MPN 11-909)

NEO tools thread repair inserts for M12 threads, kit of 10 pieces is designed to restore damaged or worn internal M12 threads to original dimensions and provide a reliable threaded connection for bolts and fasteners. The kit contains multiple helical inserts sized for M12 applications and is intended for use in metal and alloy components where thread reinforcement or repair is required. The inserts are compatible with standard M12 bolts and are suitable for repetitive assembly-disassembly cycles in maintenance, automotive, industrial and DIY environments.

Advantages

The repair inserts restore thread integrity without the need to replace the parent component, reducing downtime and material waste. Their helical coil design distributes load across the parent material, improving joint strength and resistance to wear. The kit format of 10 pieces provides a ready supply for multiple repairs and small projects. Inserts are corrosion-resistant and compatible with common fastening practices, allowing secure torque transfer and repeatable connections.

Suitable for

• Repairing stripped or damaged M12 internal threads in steel and non-ferrous alloys
• Reinforcing threaded holes subjected to frequent assembly and disassembly
• Automotive repairs such as engine components, brackets and housings
• Industrial maintenance of machinery, frames and fixtures
• DIY and workshop projects requiring reliable M12 threaded connections

Key specifications

• Thread size: M12
• Quantity: 10 inserts per kit
• Type: helical coil/threaded insert for repair and reinforcement
• Material compatibility: suitable for use in steel and common metal alloys
• Intended use: internal thread restoration and reinforcement

How to use

Drill out the damaged thread to the recommended drill size for the M12 insert, then use the provided threading tool to tap the insert thread. Install the helical insert into the tapped hole using the installation tool or driver, ensuring the insert sits flush with or slightly below the component surface as specified. Break off the tang if present after full seating, and verify the restored thread by fitting an M12 bolt to confirm correct engagement and torque retention. Follow standard safety practices and use appropriate cutting fluids when drilling and tapping.

Usage recommendations

For best results, match insert material and size to the parent material and operating conditions. Pre-clean the hole of debris and corrosion before installation. When repairing high-stress or critical components, verify specifications and torque values specified for the application and consider professional evaluation for safety-critical repairs.
