M3*18*5.3MM Brass Knurled Injection Molding Nut OD=5.3MM

The M3×18×5.3mm Brass Knurled Injection Molding Nut is a high-strength threaded insert engineered for thermoplastic embedding applications. Designed with a knurled outer surface, this insert ensures excellent torque and pull-out resistance when installed into plastic components. It is made from precision-machined brass, offering excellent wear and corrosion resistance while maintaining structural integrity under frequent use.

The M3 internal thread accommodates standard metric screws, while the 18mm length and 5.3mm outer diameter provide a secure fit in a variety of molded or 3D-printed plastic housings. This makes the insert ideal for products requiring strong, reusable threads in softer plastic materials.
