80-Piece M8x1.25 Helicoil Threaded Insert Set – Stainless Steel 304, Various Lengths (1D To 3D) For Thread Repair

About This Product

If you've ever stripped a thread in aluminum, magnesium, or soft metal, you know what a pain it is to fix.
This helicoil set gives you 80 stainless steel inserts in M8x1.

25, with a range of lengths from 1D to 3D – that's 20 pieces of each 1D, 1.
5D, and 2D, plus 10 each of 2.

5D and 3D.

Plenty to handle repairs on engine blocks, equipment housings, or any soft material that needs a strong, durable thread.

Made from 304 stainless steel, these inserts are corrosion-resistant and strong.

Once installed, they create a thread that's actually stronger than the original, especially in softer metals.
The coil design distributes load evenly across the threads, absorbs vibration, and prevents screws from backing out – great for applications with high safety requirements.

They also help if you need to frequently disassemble and reassemble parts, since they're more wear-resistant than plain threads.

Installation is pretty straightforward if you have the right tap and tool (not included).
They're a lifesaver for saving expensive parts that would otherwise be scrap.
Good kit to have in any workshop or garage.
