Easy way to fix a costly issue
I the fix the kick stand on my motorcycle with this kit. It would have cost me over $80 to by a new kick stand and I got this kit for 1/4 that. Time will tell how well it works.

Saved me massive headache with my bicycle
Had to create a new thread on an electrical bike. This tool saved me massive headaches. Worked like a charm!

This is a complete kit that will get the job done.
A complete kit that gets the job done. Be aware that the coils themselves are short. They worked OK for my application, but I would have liked to have longer/deeper coils.

Great product and way easy to use.
E-Z is right! I’ve used many differty types and brands of thread inserts and this is by far the easiest. Two tips, use a very very small dab of blue thread lock to hold in the insert permanently and remember you have to supply your own tap wrench to hold the supplied tap. Great product, made light work of a sometimes troublesome fix.
