ACME Trapezoidal Screw with Surface Treatment

Customization Services

① Surface Treatment Customization: We provide one-stop customized surface treatment solutions according to customers’ application scenarios and performance requirements, including standard options (black oxidation, zinc plating, nickel plating, nitriding, carburizing, PTFE coating, QPQ) and personalized customization (such as special anti-corrosion coating, high-temperature resistant coating) for special working conditions (strong corrosion, high temperature, high friction). Each surface treatment is strictly tested to ensure it matches the screw’s material and application needs.

② Product Specification Customization: Beyond the standard parameters (major diameter 6.35mm-38.1mm, lead 1.27mm-12.7mm), we support customized design of major diameter, lead, pitch, thread start number, and end machining (such as drilling, tapping, grooving) according to customers’ drawings and equipment requirements.

③ Material Matching Customization: According to the surface treatment type and working load, we customize material matching solutions—for example, matching alloy steel with nitriding/carburizing treatment for high-wear scenarios, and carbon steel with zinc plating/nickel plating for general anti-corrosion needs; we also support customized material selection (stainless steel, brass, PEEK) to adapt to different complex working conditions.

④ OEM & Label Customization: We provide OEM services, including customized packaging, product labeling, and logo printing, to meet the branding needs of global buyers; we also support customized quality inspection standards according to customers’ industry requirements.

⑤ Technical Scheme Customization: Our professional engineering team provides customized technical schemes, including surface treatment selection, material matching, and performance optimization, to solve the pain points of customers in complex industrial scenarios (such as severe corrosion, high load, and long-term transportation).

Product Features

① Specialized 29° ACME Thread Design: Different from the standard 30° metric trapezoidal screw, the 29° included thread angle and wider thread root design effectively reduce stress concentration, the ACME Trapezoidal Screw with Surface Treatment enhances fatigue resistance under repeated loading, and improve load-bearing capacity and stability, making it suitable for heavy-load and high-stress industrial scenarios.

② Targeted Surface Treatment Advantages: Each surface treatment is tailored to specific performance needs—QPQ treatment for superior anti-corrosion and wear resistance, PTFE coating for low friction and chemical resistance, nitriding/carburizing for improved hardness and fatigue resistance, and zinc/nickel plating for cost-effective anti-corrosion and long-distance transportation protection.

③ High Compatibility with American Standards: Standardized according to the American system, the product is fully compatible with American-style equipment and components, avoiding matching problems in global procurement and reducing replacement costs for buyers.

④ Excellent Durability in Complex Conditions: The combination of ACME thread’s inherent strength and advanced surface treatment effectively resists corrosion, wear, and environmental degradation, ensuring stable operation and long service life even in harsh working conditions (high humidity, chemical corrosion, heavy load).

⑤ Precise Transmission Performance: Through advanced thread rolling and CNC machining processes, the thread profile, pitch, and lead accuracy are strictly controlled, ensuring precise and stable power transmission, and matching the efficiency requirements of plastic and bronze nuts (consistent with the parameters table).

Product Advantages

A key built-in advantage of the ACME thread form is its superior fatigue resistance under repeated loading. Thanks to its broader root design—wider than that of the standard trapezoidal profile—it minimizes stress concentration and boosts overall durability. However, when carbon steel serves as the base material, the ACME Trapezoidal Screw with Surface Treatment’s natural strength can take a significant hit from environmental factors like corrosion and wear. This is why advanced surface treatments are a critical post-manufacturing step: by adding a protective layer, they substantially extend the screw’s service life and enhance its operational reliability.

FAQs

1. How do you determine the most suitable surface treatment for my ACME trapezoidal screw based on my application scenario?

Our technical team will conduct a detailed analysis of your application scenario (including working environment, load, temperature, service life requirements, and transportation needs), then recommend the most cost-effective surface treatment solution—for example, recommending PTFE coating for chemical corrosion scenarios, nitriding for high-wear heavy-load scenarios, and QPQ treatment for superior anti-corrosion and wear resistance needs, and provide relevant test reports for verification.

2. What is the lead time for customized ACME trapezoidal screws with special surface treatment?

The lead time depends on the complexity of customization: for standard surface treatment (zinc plating, black oxidation) and standard specifications, the lead time is 7-10 working days; for special surface treatment (QPQ, PTFE coating) and non-standard specifications, the lead time is 10-15 working days; we will optimize the production schedule to ensure on-time delivery and feedback the production progress in real time.

3. Can you provide test reports for the surface treatment performance (such as corrosion resistance, hardness) of ACME trapezoidal screws?

Yes, we can provide detailed surface treatment test reports according to your requirements, including neutral salt spray test reports (for anti-corrosion performance), hardness test reports (for nitriding/carburizing treatment), and friction coefficient test reports (for PTFE coating), all of which are compliant with international industrial standards and ensure product quality is traceable.

4. Do you provide after-sales service for customized ACME Trapezoidal Screw with Surface Treatment, such as maintenance and replacement?

Yes, we provide a 12-month quality guarantee period for all products. We provide long-term after-sales maintenance guidance, including surface treatment maintenance methods and screw service life extension suggestions, to help you reduce operation and maintenance costs.
