Use thread insert tools to install helical threads into a drilled hole or repair a stripped screw or bolt thread. Since a threaded insert is as strong or stronger than the original, it can extend the life of structures and machinery. A mandrel and nosepiece is usually included, and you can purchase additional fittings depending on the project. Grainger has everything you need for thread repair, including prewinders and extraction tools. Shop today!
