Riley N. ★★★★★

Fixed three stripped bolt holes in my aluminum engine block last weekend and the stainless steel inserts seated perfectly with the included tooling. The 31-piece kit gave me spare coils and taps, which was handy since I botched the first attempt. Honestly, this saved me from having to drill and tap

Sebastian ★★★★★

Had a stripped thread in my motorcycle brake caliper and this kit saved me from replacing the whole part. The stainless steel coil insert went in smoothly and now the bolt holds tight as new.

Hannah G. ★★★★★

Stripped a critical bolt on my mower and this kit saved me--the stainless insert grabbed perfectly and feels stronger than the original threads.
