Dutux Knurled Brass Inserts (DBI-050) are precision-engineered threaded inserts designed to provide strong internal threads in plastic, wood, thermoplastics, and composite materials. Their knurled outer surface enhances grip, prevents rotation, and improves pull-out resistance when installed in molded or drilled components. Manufactured from high-quality free-cutting brass, these inserts offer excellent machinability, corrosion resistance, and long service life. Widely used in plastic molding, electrical components, furniture fittings, and automotive assemblies, they ensure reliable threaded fastening. Dutux manufactures these inserts in various shapes, knurling patterns, and thread standards, with custom designs available as per customer drawings or technical specifications.
