• Electronics & Instrumentation: For manual adjustment in test equipment, communication devices, audio gear, and industrial control panels.
• Medical Devices: In diagnostic tools, surgical instruments, and lab machinery, where sterile, corrosion-resistant, and manually operable fasteners are critical.
• Industrial Machinery & Automation: As manual adjustment screws in fixtures, jigs, and machinery components requiring tool-free tightening.
• Consumer Electronics & 3C Products: In custom enclosures, audio systems, and wearable devices for aesthetic and functional assembly.
• Custom Furniture & DIY Projects: For bespoke hardware, cabinetry, and creative engineering prototypes requiring precise manual fastening.

· Production Process Introduction

1. Raw Material Sourcing: Procure certified metal rods (aluminum, brass, carbon steel) with uniform mechanical properties and composition.
2. Precision CNC Machining: Utilize multi-axis CNC lathes to shape the screw bodies, machine precision threads, and create knurled surfaces with exacting grip and dimensional consistency.
3. Surface Treatment: Apply plating (Nickel, Black Oxide), anodization, or polishing to enhance corrosion resistance, wear protection, and aesthetic quality.
4. Deburring & Quality Inspection: Remove machining burrs and conduct dimensional CMM scans, thread integrity tests, and visual audits to ensure compliance with strict industry standards.
5. Packaging Preparation: Individually wrap each screw in anti-scratch film; organize in partitioned trays or labeled boxes to prevent abrasion and enable easy inventory management.

· Packaging and Shipping Methods

• Packaging: Each screw is protected with anti-scratch film and packed in partitioned trays or labeled boxes. For bulk orders, components are secured in custom foam-lined containers to avoid contact and damage.
• Shipping: We offer flexible logistics options including Express Delivery (DHL/FedEx/UPS), Air Freight, and Sea Freight. Shipping methods are tailored to order volume, delivery timeline, and destination, with full tracking and damage insurance.
