Corrosion Resistant Brass Through Bore Insert Nut is a high-performance embedded threaded fastener specially designed for injection molding and hot melt embedding installation. Made of high-quality brass material, this through-hole insert nut features excellent anti-corrosion, anti-rust and oxidation-resistant properties, far exceeding ordinary iron and steel fasteners.
With standard through bore design and knurled outer surface, the nut can be firmly embedded inside plastic shells and plastic parts during injection molding or hot pressing process. It effectively solves thread loosening, slipping and falling off problems, providing durable and stable threaded connection points for plastic products.
This embedded nut adopts high-purity brass raw material with stable metal characteristics. It will not rust in humid, indoor and conventional working environments, and has great resistance to oxidation and weak chemical corrosion. The brass material owns good toughness and ductility, avoiding cracking and deformation during high-temperature embedding and injection molding processing, ensuring long-term service stability of product structure.
The full through-hole structure realizes full penetration threading, supporting longer screw assembly and deeper locking stroke. It is suitable for thick plastic parts and through-hole assembly scenarios. Compared with blind hole nuts, the through bore design allows smoother assembly, easier cleaning and no residual sundries inside the thread, greatly improving assembly flexibility and qualification rate.
The outer wall is processed with professional knurling technology to form uniform and three-dimensional textured patterns. During injection molding and hot melt embedding, the plastic material can fully wrap the knurled layer. After cooling and shaping, the nut achieves strong anti-rotation and anti-drop performance, which can effectively resist torsion and pulling force, never loose or rotate during long-term use.
Internal threads are processed by precision tapping equipment with standard pitch, complete tooth shape and smooth inner wall without burrs. It perfectly matches standard screws of corresponding specifications, ensuring smooth locking and disassembly. The thread has high wear resistance, maintaining stable fastening effect after repeated assembly and disassembly.
All brass through bore insert nuts are strictly inspected in dimension, thread precision and appearance before delivery to ensure stable product quality. We support standard size batch supply and non-standard customization according to drawings and samples, including special thread specifications, outer diameter, length and knurl styles. Suitable for small batch trial production and large-scale mass procurement, providing reliable embedded fastening solutions for the plastic molding industry.
