Press-fit threaded inserts are precision-engineered components designed to create durable internal threads in thermoplastics, composites, and soft metals. These inserts are installed by pressing them into a pre-drilled hole slightly smaller than the insert’s outer diameter, generating an interference fit that holds the insert in place without adhesives or thermal bonding.
Manufactured with knurled, grooved, or diamond-patterned exteriors, press-fit inserts resist axial and rotational forces, ensuring long-term thread reliability even under repeated torque loads. They are commonly used in plastic enclosures, structural components, and 3D-printed parts where metal threads are needed to improve strength and longevity.
