Stainless Steel Trapezoidal Lead Screw
Suzhou Maitu factory has specialized in the production, sales, and solution services of China Stainless Steel Trapezoidal Lead Screw for 12 years. Trapezoidal lead screws are fundamental mechanical components that convert rotational motion into precise linear motion. The 30°trapezoidal lead screws we manufacture are specifically designed to meet diverse customer requirements, delivering an exceptional balance of capacity, reliability, and cost-effectiveness for a wide range of industrial applications.
A key attribute that sets Suzhou Maitu durable stainless steel trapezoidal lead screws apart is their 30-degree thread angle. Unlike the acute V-threads utilized for fastening applications, trapezoidal screws feature a 30° included flank angle, with both the root and crest aligned parallel to the screw’s central axis. This specialized design—standardized under international frameworks such as ISO metric trapezoidal screw specifications—is engineered specifically for power transmission and load-bearing functions. The term "trapezoidal" originates from the trapezoid-like appearance of the thread profile when observed in cross-section.

Product Highlights
A notable intrinsic property of trapezoidal screws is their self-locking capability. In practical terms, this means that a force exerted on the nut will not induce reverse rotation of the screw. This non-reversible characteristic serves as a vital safety element in equipment like vertical elevators, jacks, and positioning mechanisms. However, self-locking efficiency diminishes as the lead angle increases; consequently, the lead angle is typically restricted to below 5 degrees, and we offer corresponding calculation data to support your evaluation and selection process.
Product Materials
Our Stainless Steel Trapezoidal Lead Screw can be fabricated from a range of materials. Typically, our production in stainless steel is for SS303, SS304 and S316L. For enhanced performance and longevity, the trapezoidal nut is often made from a softer, wear-resistant material like brass, bronze or an engineered polymer. We also provide customized end configurations and nut shape fabrication in accordance with customer-supplied drawings.

FAQs
1. How to choose between SS303, SS304, and S316L stainless steel for my trapezoidal lead screw?
Our technical team will recommend the most suitable grade based on your application scenario: SS303 is ideal for general industrial scenarios with low corrosion requirements and high machinability; SS304 is suitable for medium corrosion environments (e.g., humid workshops); S316L is recommended for strong corrosion scenarios (e.g., chemical plants, marine environments) and high-temperature working conditions, and we provide material certification for each grade.
2. What is the lead time for bulk orders of the products?
For standard specifications and common stainless steel grades (SS303, SS304), the lead time is 10-15 working days; for non-standard customization or special grades (S316L), the lead time is 15-20 working days, and we will optimize the production schedule to ensure on-time delivery and feedback progress daily.
3. Can you support stainless steel trapezoidal lead screws with non-standard parameters?
Yes. We fully support non-standard customization—you only need to provide detailed requirements (major diameter, lead, pitch, start number, end machining, and application scenario), our engineering team will design a suitable scheme, produce samples for your test verification, and carry out bulk production after sample confirmation.
4. Do you provide on-site technical support for the installation and commissioning?
Yes. We provide on-site technical support (subject to negotiation) for large-batch orders or complex application scenarios; our technical personnel will go to your site to guide installation, commissioning, and provide maintenance training, helping you avoid installation errors and ensure the product operates stably.
