FAQ

Selection-related

Q1: What are the dimensions and strength grade range of the SCREW screws? How to select them accurately?

A1: The dimensions cover all specifications from M3 to M64, divided into three categories: precision (M3-M12), general (M14-M36), and heavy load (M39-M64); the strength grades are 4.8-12.9, with 4.8 grade suitable for light load, 8.8 grade for general use, and 10.9-12.9 grades suitable for heavy load. The selection can be made based on the application industry, force conditions, and environmental factors.

Q2: What are the differences in application scenarios for carbon steel, stainless steel, and alloy steel screws?

A2: Carbon steel has high cost performance and is suitable for indoor dry ordinary scenarios; stainless steel is corrosion-resistant and suitable for humid, outdoor, and coastal environments; alloy steel is high-strength and anti-fatigue, suitable for heavy-load, high-vibration industrial scenarios (such as construction machinery, rail transit).

Technical-related

Q3: What are the advantages of the SCREW screw's anti-loosening design and which scenarios are suitable for it?

A3: It adopts multiple anti-loosening schemes to resist vibration and impact that may cause loosening, reducing maintenance costs, and suitable for vibrating scenarios such as automobiles, rail transit, and mechanical equipment.

Q4: What are the precautions for using high-strength (10.9/12.9 grade) screws?

A4: The pre-tightening force needs to be controlled to avoid overload and fracture; after electroplating, hydrogen needs to be completely removed, and outdoor use requires an anti-corrosion coating to prevent stress corrosion.

Procurement and Customization-related

Q5: Are there regular-sized screws available in stock? How long is the delivery cycle?

A5: Regular-sized screws with specifications from M3 to M64, strength grades from 4.8 to 12.9, and common materials and surface treatments are available in stock. Orders will be shipped within 1-3 working days.

Q6: Can non-standard-sized screws be customized? What is the process and cycle?

A6: Customization is possible. Personalized requirements such as size, strength, and material can be provided; the process: provide parameters → engineer evaluation → quote and sample production → confirmation of production, with a cycle of 5-10 working days.

Industry and Environment Adaptation-related

Q8: Which core industries are the SCREW screws suitable for? Are there dedicated solutions?

A8: It is suitable for six industries: automotive manufacturing, home appliances and electronics, building steel structures, mechanical equipment, new energy, and rail transit. Dedicated adaptation solutions are provided for each industry's working conditions.

Q9: Are there special protections for outdoor/high-temperature environment usage of screws?

A9: There are dedicated protections: outdoor use stainless steel + hot-dip galvanizing/anti-corrosion; for high temperature (≤500℃), use heat-resistant alloy steel + high-temperature coating; for low temperature (≤-70℃), use low-temperature-specific materials.

 Installation and Maintenance-related

Q10: What are the key precautions for screw installation?

A10: ① Clean the bolts and connection parts of impurities and oil stains; ② Control the tightening torque; ③ For vibration scenarios, pair with anti-loosening accessories; ④ Before assembling stainless steel screws, apply a dedicated lubricant.

Q11: How to extend the service life of screws and what are the daily maintenance precautions?

A11: ① Select matching usage environments; ② Regularly check the tightening status, replace damaged parts in time; ③ Regularly perform anti-corrosion maintenance for outdoor screws; ④ Avoid overloading use.
