Keenserts are a specialized type of threaded insert known for their strength and reliability in high-stress applications. The trademark for Keenserts was filed with the United States Patent and Trademark Office on August 1, 1958. These inserts are designed to provide high resistance to torque-out and pull-out loads, making them ideal for situations where fasteners may be repeatedly removed and reassembled.
Keenserts are manufactured by Howmet Aerospace Inc., a company known for its high-performance fastening systems. They are particularly valued in industries such as mechanical engineering, aviation, aerospace, and marine applications where thread stripping and corrosion are concerns. The design of Keenserts includes pre-assembled keys that are driven down through the threads of the parent material to mechanically lock the fasteners into place, providing a secure connection even in challenging environments.
Today, Keenserts remain a preferred solution for thread repair and strengthening in various materials, including ferrous, non-ferrous, and non-metallic substances. Their ability to withstand high torque and temperature makes them a reliable choice for critical applications across multiple industries.
