M6x1.0 Thread Repair kit #1610

Pricy but the best thread repair out there.

I think this is the first review I have ever left on Amazon. However, I am so pleased with the Time-Sert product I had to leave a review. I am a small time Porsche collector and have always collected air cooled cars. Recently, however, the price of the water cooled 911's (996) have reached a point that I thought it was time to add one to the fold. After buying a 1999 911 the first step was to change the oil and drop the sump plate to look for IMSB and timing chain guide debris. You can imagine my disappointment when the head of one of the M6 bolts holding the sump plate broke off! Apparently, this is a common issue. The engine (being in the rear of the car and somewhat low) sometimes bottoms out on bumps, curbs, etc. Even if the sump plate doesn't crack, the bolts will stress fracture and beak on removal. (BTW...the oil in sump plate was very clean. So, there was some good news in all this). Anyway, after dropping the sump plate there was just a little bit of the bolt protruding from the bottom of M96 engine's aluminum block. Trying vice-grips to remove the bolt did nothing. There wasn't enough bolt to grab. Next, I tried JBWelding a nut to the protruding bolt. That was useless. Lastly, I tried drilling out the bolt with a left handed drill bit (hoping that the left handed drilling action would unscrew the bolt). No luck, there. At this point, I had run out of "easy" options. I knew I was going to have to either drill out the bolt with a larger drill bit and retap for a larger bolt or try a Time-Sert and/or Helicoil. After researching my options, I settled on the Time-Sert. Using Amazon Prime the kit arrived in two days. After arrival I watched the videos on YouTube (again) and went through the process in my mind. It was with some trepidation I approached the car knowing that a used engine (not rebuilt) is $7500 to $10K for these cars. My anxiety level was high. However, once I got going it was really quite easy. The whole process took 30 minutes from start to finish with me taking numerous breaks to verify my work and plan the next step. The payoff came at the end when the time-sert was in and I offered the sump plate back up to the car. The bolt went in easily and torqued down to the required 10 N-m with no issue. Success! I found the kit was pretty complete. I did add the following to help me: Oatey 30200 Clear Cutting Oil for the drill and tapping. Time-Sert Tap Guide part # 36105 (VERY useful for making sure the tap was perpendicular to the block). Lisle L170500 Tap socket set for driving the tap and insertion tool. Based on this experience, I know I have a new tool in my arsenal should I break another bolt!

The quality is top notch. I had stripped threads inside my engine block, and wasn't able to tap larger threads. This time sert kit saved my engine block, and I've very confident in the repair. I also used it on plastic threads for my radiator, and for the upper radiator mounts. So far, I've used 5 inserts and I feel like I've gotten my money's worth. I highly recommend it to anyone

I've been using these for years, though primarily in larger sizes (M12, M10 and M8) for common aluminum parts where the threads strip out of them after repeated use (or after the previous parts hanger overtightened the snot out of something) on various German cars I work on. This time it was my fault. Supplier had send me the incorrect bolts for injector hold downs in a PD style VW diesel. I knew they were incorrect and went for it anyway, pulled threads from 2 out of 4 bolt holes. Even with the longer original bolts those two wouldn't tighten down. So, emergency order of this thread repair kit AND a set of the 12 mm long inserts on a Saturday night, and they were here Monday afternoon thanks to Amazon shipping. Time-serts never fail to impress me. Quality repair, relatively easy to do and they last. I cannot describe how much higher I rate these over heli-coils. Not even a contest. 5 star product and 5 star fast shipping from Amazon even when ordered on a weekend.

This is one of the few unique tools out that that actually works as its supposed to. The instructions are clear and easy to follow for a first timer. I found that using in on a vintage UJM was far better than helicoil or tapping a whole new thread for a bigger bolt. I will say that the price point is a bit high for what you get. The tool can only be used on one specific size and only comes with 5 inserts. This means that if you only have a one off fix, at $70+ a kit, I might just be cheaper to buy a whole new part. It also means that it can get extremely expensive having to repair multiple sizes. In the end, the fix is solid. And if I come across an issue again, this will my first go to. I just hope its the very same size i had already bought....

Top and i mean TOP NOTCH!!!!!!! This brand should be on every mechanics and diy persons desk! Let's get these guys out there so the price comes down:) I need more! :) I have an "older" set of m8 bought in 2013 and the drill bit is still RAZOR SHARP!!!! As you can see, I still keep the "old' m8 drill bit in the sheath!!
