Description
Through Hole Brass Knurled Insert Nut, Anti-Rotation Embedded Pre-Insert Nut for Plastic Injection Molding Custom Machining
Product Overview

Through Hole Brass Knurled Insert Nut is a widely used embedded fastener designed for plastic injection molding and hot press embedding. Manufactured from high-purity H59/H62 brass, the nut features full through-hole internal thread and outer knurl texture to provide strong anti-rotation and anti-pullout performance. After being pre-inserted into plastic parts, the knurled outer wall tightly locks with the plastic material to avoid loosening, spinning or falling off during long-term assembly and vibration. The full through-hole thread allows full penetration bolt installation, suitable for thick plastic parts, multi-layer assembly and through-fastening scenarios. Standard sizes M3/M4/M5/M6 are in stock, and fully non-standard custom machining is available according to drawings and samples.

Key Features
  • Full Through Hole Design: Complete through thread supports penetrating bolt installation, suitable for thick plastic shells and through-assembly structure.
  • Knurled Anti-Rotation Structure: Outer knurl increases combination force with plastic, effectively preventing nut spinning and pull-out.
  • High-Quality Brass Material: H59/H62 brass offers corrosion resistance, oxidation resistance and stable thread hardness, no rust for long-term indoor and outdoor use.
  • Precision Thread Machining: Smooth and standard thread pitch ensures repeated disassembly without slipping or thread damage.
  • Dual Installation Methods: Support injection molding pre-embedding and hot press embedding for different production processes.
  • Full Customization: Custom outer diameter, length, thread pitch and knurl shape for special plastic structure requirements.

Frequently Asked Questions
Q: What is a through hole brass insert nut used for?
A: It is an embedded fastener pre-buried in plastic injection parts, providing durable internal thread connection for through-hole assembly and multi-layer fastening.
Q: What is the difference between through hole and blind hole insert nut?
A: The through-hole type has full penetrating thread, suitable for penetrating bolt installation; blind hole type is closed bottom for anti-glue and shallow installation.
Q: Can you customize special sizes?
A: Yes, we support custom outer diameter, length, thread and knurl pattern based on drawings or samples.
Q: Is brass insert nut better than steel nut for plastic parts?
A: Brass has better anti-rust performance, smoother thread and no stuck risk, more suitable for long-term plastic product use.
