Knurled Anti-Rotation Design Hex Injection Molded Insert Nut
,Through-hole Structure Knurled Embedded Nut
,Precision Machining CNC Nuts
Situo Hardware specializes in custom manufacturing of hex injection molded insert nuts, through-hole knurled embedded nuts and plastic housing pre-insert fasteners. Adopting precision turning and cold forging forming process, these knurled insert nuts are designed for injection molding pre-burying assembly.
The outer knurling structure delivers excellent anti-rotation and anti-pullout performance, effectively solving nut loosening and falling off issues during plastic shell use. Widely applied in smart home housings, electronic enclosures, instrument plastic parts, automotive plastic components, communication equipment casings and other injection molding scenarios. We support non-standard customization of size, thread and material, with short lead time for samples.
- Knurled Anti-Rotation Design: Outer pineapple/straight knurl increases bonding force with plastic base, prevents spinning and pull-out under torque load.
- Through-hole Structure: Full through thread for bolt penetration, convenient assembly and connection, suitable for through installation requirements.
- Precision Machining: Uniform thread, smooth inner wall, stable tolerance, good interchangeability for mass injection molding production.
- Multiple Material Options: Brass, SUS303, SUS304 stainless steel optional, corrosion-resistant for different working environments.
- Custom Service: Custom thread specification, outer diameter, length, knurl style according to drawings or samples, small batch trial order acceptable.
- Smart home plastic housings
- Electronic equipment & instrument shells
- Automotive interior plastic parts
- Communication device enclosures
- PCB plastic brackets
- Consumer electronics injection molded components
