Product Description
Custom Engraved Patterns CNC Nuts M2.5 M3 Round Brass Nuts For Through
Round brass nuts with custom engraved patterns for through nuts, featuring CNC precision machining for superior quality and performance.
Applications in New Energy Vehicles
Specifically designed for electronic control and battery pack systems in new energy vehicles, including:
- Lock nuts for battery pack housings
- Motor fixing nuts
- Electronic control box cover nuts
- Wiring harness bracket fastening nuts
- Water cooling plate sealing nuts
CNC Production & Processing Features
- Non-standard thin, special-shaped, or short cylindrical structures
- Integrated machining of foolproof positioning grooves, sealing surfaces, insulation sections, and knurled anti-slip profiles
- Multiple material support including aluminum alloy, stainless steel, and copper alloy
- Surface treatments: anodizing (aluminum) and passivation (stainless steel) for enhanced insulation and corrosion resistance
- Precisely manufactured internal threads for miniature bolts with strict tolerance control
- Compact design supporting space-efficient layouts in battery packs and electronic control boxes
- Excellent waterproof and dustproof sealing meeting IP67 or higher protection standards
- Smooth assembly with bolts, ensuring long-term reliability without corrosion, overheating, or loosening
Common CNC Machining Solutions
Aluminum Alloy Machining
Special aluminum taps with increased cutting fluid supply and controlled cutting speed prevent adhesion and burrs, ensuring smooth internal threads.
Sealing Surface Machining
Fine milling of sealing surfaces with surface roughness controlled to Ra ≤ 1.6 μm for tight fitting with seals and preventing liquid leakage.
Foolproof Structure Machining
Strict machining of positioning grooves per drawings ensures precise matching with mating parts, avoiding assembly errors.
Insulation Section Machining
Precision turning controls insulation layer thickness and integrity, preventing damage during internal threading.
