Product Introduction

Double mesh knurl brass mold-in insert nut adopts cylindrical overall structure. Two rings separate the outer diamond grid knurls to maximize friction with plastic. Made of H59 brass, fully automatic CNC one-piece machining delivers precise, smooth inner threads without burrs or broken teeth. It provides powerful gripping force after injection molding to avoid looseness, thread slipping and falling off. Brass boasts reliable conductivity and rust resistance, resisting long-term oxidation.
