Knurled Brass Insert Nut H62 Brass Embedded Fastener for Plastic Injection

Our custom knurled brass insert nuts are precision manufactured from premium H62 brass, specially designed for embedding into plastic parts via injection molding or ultrasonic installation. Featuring multi-section knurling structure, this fastener delivers excellent anti-rotation and anti-pullout performance, avoiding loosening under torque and vibration.

All products are fully processed by professional CNC turning to guarantee accurate dimensions and standard internal threads. We complete knurling, end cutting, deburring, ultrasonic cleaning and optional passivation for rust resistance.

We are a professional manufacturer offering full OEM and custom service. We can customize size, thread, knurl style and surface treatment according to your drawings or samples. Each cnc machined brass embed nut complies with strict production standards, suitable for long-term mass production.

These knurled brass insert nuts are widely applied for threaded reinforcement of plastic parts across multiple industries:

• Consumer electronics & household appliance plastic housings
• Automotive interior plastic components
• Medical device plastic casings
• Industrial equipment plastic enclosures
• Plastic furniture, daily necessities and assembled products

As a reliable custom manufacturer, we provide one-stop OEM and custom service for brass insert fasteners:

• Custom dimensions: Length, outer diameter and inner hole size per your requirements
• Custom thread specifications: Multiple standard threads and non-standard thread pitches
• Custom knurl design: Different knurl shapes and distribution
• Material selection: H62 brass, lead-free brass and other copper alloys
• Custom surface treatment: Passivation and other anti-corrosion finishes
• Support sample drawing processing, prototype trial and mass production

• Multi-section knurling structure: Greatly enhance friction with plastic, solve the common problems of nut spinning and falling out during use
• High-precision CNC machining: Strict ±0.02mm tolerance, avoid assembly mismatch and thread jamming
• Premium H62 brass material: Good hardness and corrosion resistance, prevent thread wear and damage after repeated disassembly
• Optional passivation: Effectively resist floating rust, solve performance degradation in humid working environment
• Flexible custom service: Customize products according to your design to match special installation and usage scenarios

• Raw material inspection: 100% check H62 brass material before production
• In-process inspection: Real-time dimensional testing during CNC turning and knurling to keep tight tolerance
• Thread full inspection: 100% tested by thread go/no go gauges to ensure qualified thread
• Appearance check: Remove all burrs and surface defects after trimming and cleaning
• Surface treatment inspection: Verify anti-rust effect for passivated products
• Final packaging: Adopt moisture-proof packaging to prevent pollution and rust during transit
