good value for money

I've never done anything like this on my old Harley so I approached this project with care. I had to tap and insert the Helicoil into the front cylinder head to fix an engine stabilizer bracket. After watching a few videos I slowly and carefully went through the whole process and the repair was completed successfully. Now the screw is tightened to the required specification. I am confident that this solution will withstand high temperatures and vibration.

Pros
  • Item is a 3/8-16 thread repair kit
Cons
  • Hard to tell

Saves bacon as intended

As usual with any HeliCoil setup, it saved a day for my project. Mine wasn't as advertised. The installation tool was better than the diamond handle style. It came with a straight bar with a mounting hook on one end and a square drive on the other. Put a square drive in a wrench, crescent wrench, vice or whatever and screw it in. I recommend buying a good cobalt tip for this and dedicating it to the HeliCoil kit.

Pros
  • Easy to use
Cons
  • Definitely a bad product

Spirals - good economical threaded inserts

Spiral coils - good economical threaded inserts. This kit does not come with a drill like most, but you will need a standard size drill and you probably already have one. There are two ways to install a spiral coil in a threaded hole made with the included tap. With this kit, you thread the insert onto a threaded insert tool (as opposed to a tool with a shouldered steel shank). The installation tool in this set has a small advantage as it makes it easier to install the insert when you need it…

Pros
  • For repairing threaded holes
Cons
  • Some nuances

Small Block Chevy 350 Starter Bolt Hole Attachment

The starter bolt hole was cracked and loose. drilled out Hit with a whale crane. Used line oil. Did it for a long time! I would do 1/4 turn, 1/2 turn, full turn if not too much resistance then remove the faucet, clean and re-grease. I used a 1/4" spool because I wanted to read blogs and the starter bolt threads are twice the length of the spiral spool so I wanted it to be more centered. I used Red Lock Tit on the spool. we go for the night We'll see if it works tomorrow or not. Tomorrow comes I

Pros
  • Includes 12 Bits, Full Instructions, Heli-Coil Tap and Installation Tool
Cons
  • Mystery
