· Product Overview
These multi-color anodized aluminum knurled disc nuts are vibrant, user-friendly fasteners designed for tool-free manual adjustment and fastening. Crafted from high-strength 6061-T6 aluminum alloy and finished with durable anode oxidation (available in red, white, gold, blue, and black), they feature a circular disc shape, internal full-length threads, and an outer knurled texture (for non-slip hand grip). Blending functional performance (secure clamping force) with eye-catching aesthetics, these nuts eliminate the need for tools while adding a customized touch to assemblies—making them perfect for hobby projects, custom equipment, and aesthetic-focused builds.
· Core Specifications
- Material: 6061-T6 Aluminum Alloy (Anodized)Offers lightweight rigidity (tensile strength ≥290 MPa), corrosion resistance (via anodization), and excellent color retention.
- Manufacturing Standard: ISO 9001-Certified Precision CNC Machining + Anode Oxidation Process
- Key Processes: CNC turning (disc shape + internal threads + outer knurling) → Anode oxidation (vibrant color coating) → Deburring (smooth edges for safe handling).
- Key Parameters:
- Thread Type: Metric (M3–M6; customizable to UNC standards)
- Standard Dimensions: Diameter = 20mm, Thickness = 5mm (customizable)
- Dimensional Tolerance: ±0.02mm (ensures tight fit with mating screws)
- Load Capacity: Up to 15kg per nut
- Color Options: Red, White, Gold, Blue, Black (custom colors available).
· Application Scenarios
These colorful knurled disc nuts are widely used in:
- 3D Printing Equipment: Adjusting bed leveling knobs, tightening extruder components, or securing frame parts (adds custom styling to builds).
- RC & Hobby Models: Fastening body panels, adjusting suspension joints, or decorating custom model vehicles (tool-free operation simplifies tweaks).
- DIY & Handmade Projects: Building custom workbenches, furniture fixtures, or workshop jigs (vibrant colors match personalized designs).
- Electronic Enclosures: Securing enclosure panels, positioning PCB modules, or mounting small sensors (no tools needed for quick adjustments).
- Household Hardware: Manual adjustment of adjustable shelving, cabinet hinges, or folding table locks (sleek appearance complements home decor).
· Production Process Introduction
- Raw Material Preparation: Procure 6061-T6 aluminum bars (metallurgically tested for machinability and strength).
- CNC Turning: Use precision CNC lathes to shape the circular disc, drill/tap internal threads, and machine the outer knurled texture (for enhanced hand grip).
- Anode Oxidation: Submerge machined parts in electrolytic baths to apply durable, color-matched anodized coatings.
- Deburring & Finishing: Remove sharp edges (for safe hand operation) and inspect color uniformity + knurl integrity.
- Quality Inspection: Verify thread accuracy (via thread gauges), conduct CMM scans for dimensional tolerance, and confirm load capacity.
- Sorting: Group nuts by color and thread size for organized inventory.
· Packaging and Shipping Methods
- Packaging: Nuts are sorted by color, wrapped in anti-scratch plastic bags (to preserve anodized finishes), and packed in foam-lined partitioned boxes (prevents knurl damage and color mixing).
- Shipping: Flexible logistics options:
- Express Delivery (DHL/FedEx/UPS: 3–5 business days)
- Air Freight (7–10 business days)
- Sea Freight (20–30 business days)All shipments include full tracking and damage insurance.
