The brass threaded insert M4 is designed to create durable, precise and mechanically strong internal threads in plastic components. The inserts are typically installed by heat-setting using a soldering iron or by press-fitting, ensuring firm anchoring inside the material.
Thanks to the knurled exterior, they offer excellent pull-out resistance even under repeated tightening. They are ideal for functional prototypes, structural components, electronics enclosures and small assembly parts.
