Z SK30615 Threaded Stainless Installed Review

I love these ingenious tools. I have several different sizes now and they save $$$$ compared to buying replacements with the threads stripped or crossed. I used this on my Mercury outboard to repair a stripped bolt hole. As long as you know the size and thread count of the screw you want to install, the kit will do the rest. With the right size drill bit, bit, and tool, the repair takes just 15 minutes. I will continue to buy them for these occasions! No complaints!
