If you're looking for an insert that can repair the stripped or damaged threads of your equipment, Keyserts by Recoil are the perfect product for you. These specialty inserts install easily into a variety of materials, from aluminum and cold rolled steel to magnesium. Once installed, the Recoil Keysert provides a new thread with a key-locking mechanism that restricts torsion or vibration-induced rotations. Keyserts are ideal for trucks, small engines, molds, RVs and other machinery. However, we highly recommend that you avoid using these inserts with softer, more brittle materials like plastic. Our Keyserts are available in thinwall, heavy-duty, solid and extra heavy-duty styles to accommodate your specific needs. When you're ready to order, shop Bay Supply's Recoil Keysert selection below!
