Brass knurling inserts are threaded components that give strength to plastic and soft material assemblies. The knurled surface locks firmly into the base material, preventing slip during use. It keeps screws and bolts tight, even after multiple uses. These brass inserts are widely chosen in plastic molding, electronics, and industrial assemblies.
Brass knurled insert, brass threaded insert, and brass press-fit insert is common in plastic molding, electronics, and industrial assemblies. They keep fasteners stable and extend product life.
Brass knurling inserts come in different types. Each works in a specific way.
They are heated and pressed into plastic. The heat softens the plastic slightly. This makes the insert stay tight. Common in 3D printing and plastic molded parts.
Press-fit inserts are pushed into a hole. The knurled surface grips the material. No heat is needed. Used in industrial assemblies and electronics.
Vibrations embed insert into plastic. Installation is fast. Threads stay secure even after repeated use.
Screws make them expand slightly. Works well in soft plastics. Provides a firm fit that resists loosening
Brass knurling inserts keep screws and bolts tight. Heat-set and press-fit inserts hold threads firmly in plastic and metal.
Brass resists wear and corrosion. It lasts long in electronics, automotive, and industrial parts.
Knurled surfaces are accurately made. Tight tolerances ensure the insert stays secure every time.
Different types make installation simple. Heat-set, press-fit, ultrasonic, and expansion inserts fit easily, even in small parts.
Inserts create strong threads in molded plastic parts. They keep screws secure.
Inserts allow screws to fasten securely to 3D-printed parts. They improve durability and assembly quality.
Brass inserts provide firm threads in dashboards, housings, and interior plastic parts. They withstand vibration.
Inserts make threads strong and keep small plastic devices secure.
Inserts create strong fastening points in machinery and plastic assemblies. Components can be reinstalled without damage.
