Fredsert threaded inserts feature a unique external thread profile to deliver a combination of friction fit and material compression to reliably lock in place, while also providing an airtight, watertight seal. The Fredsert was designed to resist vibration, tensile loading, and shear loading in the most demanding heavy-duty applications. The patented geometry allows the insert to be quickly and easily removed and replaced using the same standard equipment. Fredserts are available in a variety of materials, including titanium and stainless steel.
