Ordering Process
Inquiry & Requirement Review
Buyers send drawings, samples, or specifications, and our team reviews technical details, materials, and application requirements.
Technical Evaluation & Quotation
We evaluate production feasibility, confirm processes and tolerances, and provide a clear quotation with lead time.
Sample Development & Approval
If required, we produce trial samples or prototypes for testing and confirmation before mass production.
Order Confirmation & Production
After sample approval, the order is confirmed and scheduled for in-house production under strict quality control.
Quality Inspection & Packaging
All products undergo inspection to ensure consistency, accuracy, and safe packaging for international shipment.
Delivery & After-Sales Support
We arrange shipment and provide ongoing support for any technical or quality-related inquiries after delivery.
Large-Caliber Precise Pressure Adjustment
The M14 large thread specification is adapted to the heavy-duty presser foot spring of 7200 models, and the pressure adjustment accuracy reaches ±2N, which can accurately match the pressure needs of multiple materials such as cotton linen, denim and leather.
Long-Stroke Compatibility
The effective adjustment stroke of the screw reaches 15mm, which can fully adapt to the long-stroke presser foot spring of 7200 models and meet the pressure compensation needs of ultra-thick materials ≤8mm.
Stable Force Transmission
The screw rod is nickel-plated for rust prevention, and the end in contact with the spring is processed with arc chamfering to avoid local wear of the spring and ensure uniform pressure transmission. The presser adjusting screw enables accurate pressure tuning for diverse fabrics.

Surface Treatment Methods of Pressure Adjustment Screw & Nut
Anodizing
Predominantly used on aluminum, anodizing thickens the substrate's natural oxide layer. This makes the surface more resistant to wear and corrosion, while also helping to dissipate heat. As a result, anodizing is a top choice for aerospace and electronics applications.
Electroplating
Electroplating deposits a thin layer of metal—such as nickel, chromium, silver, or cadmium—onto the surface of a part using an electric current. This enhances corrosion and wear resistance while also improving heat performance. Electroplating is widely used in aerospace, electronics, and automotive applications for both functional and aesthetic benefits.
Chemical Conversion Coating (Chem-Film)
Chem-film coatings offer corrosion resistance without adding significant thickness. These coatings are ideal for applications where electrical conductivity must be maintained while still protecting the metal from environmental damage.
Electroless Nickel Plating
Electroless nickel provides a uniform, highly corrosion-resistant coating even on complex geometries. High-phosphorus variants offer excellent chemical and heat resistance, making them popular in oil and gas, defense, and chemical processing industries.
Passivation
The passivation process removes contaminants and enhances the natural oxide layer on stainless steel, improving corrosion resistance without altering the dimension or appearance of the part.
