Material
Made of 6061 aluminum alloy with black anodized surface treatment (corrosion-resistant, lightweight, and high in hardness).
Process Standard
Compliant with the ISO 9001 quality management system, with thread precision, knurled texture, and surface treatment all meeting industrial-grade requirements.
· Application Scenarios
- Photography Equipment: Quick connection/fixation for tripods, quick-release plates, camera cages, etc.
- Industrial Equipment: “Tool-free” disassembly and assembly for automation equipment, instrument panels.
- DIY Projects: Assembly for furniture, models, chassis (computer/model chassis), and other handmade items.
- Stage Lighting: Quick adjustment and connection of lighting equipment accessories.
· Production Process Introduction
- Raw Material Selection: High-purity 6061 aluminum alloy bars are selected to ensure strength and toughness.
- Precision CNC Machining: The screw and knurled head are integrally formed, with dimensional accuracy reaching ±0.02mm.
- Thread Rolling: The “thread rolling process” (non-cutting) is adopted, making the thread stronger, the surface smoother, and the engagement tighter.
- Anodizing Treatment: Black anodizing not only gives a matte texture but also enhances surface hardness and corrosion resistance, extending the service life.
- Full Inspection Before Delivery: Each batch of products undergoes three inspections: “thread go-no-go gauge, dimensional tolerance, surface quality” to ensure quality.
· Packaging and Shipping Methods
Packaging
- Inner Packaging: Individual packaging for each piece or based on order quantity (10 pieces/bag, 50 pieces/box, etc.) to prevent scratches.
- Outer Packaging: Hard cartons + bubble film for cushioning to avoid deformation during transportation; specifications and quantities are marked on the packaging for easy identification.
Shipping
- Logistics Methods: Support DHL/UPS/FedEx (international express, 2 - 7 days delivery), postal parcels (an economical option for small batches), and sea freight/air freight (for large orders).
