## Questions & Answers

**Q: Anyone try this kit to repair side post battery terminals?**
A: Kit worked great.  I will buy another set if I need it

**Q: What’s the installed thread length of the inserts? Specifically 5/16-18**
A: Did not measure the insert length, but most inserts are approx 1/2" long in this size range. It only has to be as long as the diameter of the boat to be full strength.  So if it is a 5/16 insert the insert needs to be at least 5/16 long. These are. But the tool is junk, I suggest buying a name brand US. Made tool.

**Q: will this work on .9 thread?**
A: This kit is for 5mm .

**Q: If the thread id of the helicoil is m8x1.25, so what is the od of that helicoil?**
A: You purchase the kit you need depending on the thread type you are attempting to repair.

    It Fixed What I Needed Fixed
  

*by J***N on Reviewed in the United States on 4 November 2024*

After I incompetently NUKED the threaded brass threads on a LiFePO4 battery (while POORLY attempting to hook the batteries in series, resulting in welding a brass bolt into the cable lugs...PLASMA!!), I debated between installing a "Helicoil" type repair such as offered by this kit , versus expanding the bolt used from M8 to M10 via drilling/tapping the hole larger.I've still got the M10 tap on order from a large online seller beginning with E and ending with AY.  That should show up...ummm....sometime.  Being the impatient male of the species, I ordered this kit via overnight Prime delivery.I decided to try a thread insert repair, for the FIRST TIME.It did the job.  I used Tapmagic threading/cutting fluid as a lubricant, took my time, and worked the tap in & out to remove chips.  No broken taps, no (OK, only just a couple) unhappy words.Minor grumbles: - The kit does not include the dinky hex wrench needed to loosen the setscrew on the tool used to insert the repair thread.  Not absolutely necessary, but still handy. - After inserting (screwing in) the threaded insert, the insert GRABBED onto the tool, making it a royal pain to extract.  Brute force won out.I chose to use a generic red Loctite-style thread locker to secure the thread repair insert into the repair area.  Probably not necessary, but such is life.

    Advertised correctly, no scam
  

*by D***C on Reviewed in the United States on 17 November 2024*

It's a solid kit and the inserts fit nicely both to the O.D. thread and to the I.D. thread. I would recommend this kit. Only reason I didn't give it 5 stars is because there is no threaded guide for starting the inserts straight. Though I had no issues,  I have with other inserts in the past.
