A thread repair kit for stripped, worn or damaged M6x1 metric coarse threads, so the original-size fastener can be reused. The carded kit holds 12 stainless steel inserts (9.0 mm long), the matching HeliCoil tap (570-6) and an installation tool (3747-6). A 1/4 in drill is needed and is not included.
- Restores stripped, worn or damaged threads to their original size, so the original-size fastener can be reused
- Inserts are precision-formed coils of hard 18-8 stainless steel diamond-shaped wire
- Works in almost any part material, including aluminum, magnesium, cast iron and bronze
- After installation each coil expands against the tapped hole and anchors permanently
- Insert has a notched driving tang for installation and easy removal
- Repaired thread resists thread wear, corrosion, galling, seizing and rust
Warnings
- Drill out the damaged threads with the drill size given on the kit (1/4 in), deep enough for the insert length and the bolt or screw used
- Use the HeliCoil tap supplied in the kit and check the size on its shank; tap deep enough for the insert length and the bolt or screw used
- Wind the insert in with the supplied installation tool until the top coil is 1/4 - 1/2 turn into the tapped thread
- Remove the tang so the bolt can pass fully through the insert: put the square (unchamfered) end of a punch on the tang and strike sharply
