E-Z Lok EK51210 Metric Helical Threaded Insert Kit, High-Quality 304 Stainless Steel, M16-1.5 Thread Size, 16 mm Installed Length (Pack of 5) Review

A few things you should know. The right drill makes all the difference. Not just the right size (yup), but when drilling metal, don't waste forever on the wrong drill bit. Get something for metal. The other element is the thread lock.

Bought to fix stripped threads in oil pan. The kit came with the wrong faucet. Probably M14-1.5, complete with tap M14-1.25. If you compare the supplied threaded inserts with the tap, you will notice that they have different pitches. Totally useless and a huge waste of valuable garage time.

I've used the smaller EZ-Lok kits (smaller threads) successfully, but this larger 14MX1.5 kit had a poorly made tap that wouldn't start even with the right one Oil drain hole in the Crankcase of my VW. Upon closer inspection, the initial threads on the flutes of the tap appeared dull. I tested it on a 3/8 piece of aluminum and was able to run the faucet but it gouged the hole pretty hard. If I had continued I would have ruined the crankcase. I had to return the set but did not receive another…

it works really great - if you follow 3 simple steps (1 - drilling, 2 - tapping, 3 - insert assembly) with the tools included in the same set, it's enough what he says he will do. I have a road bike and therefore require constant maintenance and the need to frequently remove certain parts (seat, fairings, etc.) to perform this maintenance. Since the chassis is aluminum, you almost expect the threads on the screws holding these parts to snap at some point. I have already done 3 frame repairs on…

Good: The tap and the tool worked great and are of good quality. Terrible: The spiral coils in my kit were the wrong size. I ended up buying more from Helicoil for a little over $10 a box. These were smaller than what I received in this kit which ended up fitting properly. I spent hours installing the wrong size coil spools that kept breaking shanks after barely putting them in, which were shipped in my kit. This was annoying and also delayed my work of sending the correct sizes. I wanted to…

I almost did it worse with this set. I still give 5 stars because it was my mistake. I've never used either of these before so after watching a few YouTube videos I figured I knew exactly how to do it! What can go wrong? Well, for some stupid reason, while screwing the coil, one of the cables jumped.! So when I started tightening that bolt, oh my god. It was a damn hard job cleaning everything up. I rethreaded and the next time I actually checked the loops, the same thing happened! After 2 more

I ordered the economy kit M14-1.5 (Length 1.5D/21mm) but like the other reviewer I received a kit that was a kit in a different size included. Mine was marked as ordered but included parts for a 1/2-20 (1D/14mm) kit which I identified both by the tap print and compared to the screw to be installed and the picture of the thread pitch of Bolt Depot fasteners. PDF tools (be sure to print at 100% scaling). Please note that you have to stretch the spools to measure according to the pitch pattern…
