BILITOOLS Helicoil Thread Repair Kit M7x1.0 — Metric M7 Insert Kit with HSS Drill & 304 Stainless Inserts

The BILITOOLS M7x1.0 Helicoil Thread Repair Kit is a complete metric thread restoration set that replaces damaged M7x1.0 internal threads with durable 304 stainless inserts for long-lasting, high-torque repairs.

This compact kit equips mechanics, hobbyists, and tradespeople with the drill, tap, installation tools, and stainless steel coil inserts needed to restore stripped or worn threads in metals, composites, and polymers. All components are organized in a sturdy iron case for easy transport and repeatable results on automotive, plumbing, and general repair tasks.

How does the kit restore stripped M7x1.0 threads?

The kit restores stripped threads by drilling out the damaged thread, tapping a new oversize thread, and inserting a stainless-steel helicoil that provides a fresh, factory-fit internal thread. The included break-off tang system secures the insert and then removes cleanly after installation.

• HSS drill sized for precise hole preparation
• Tap to cut the new thread for the insert
• 304 stainless coil inserts replace the worn threads
• Break pin tool removes the installation tang cleanly
