Customer Questions & Answers

  • Question: What is the specification of M20-2.5 X 50mm shoulder screws?

    Answer: The M20-2.5 X 50mm shoulder screw features a diameter of 20mm, a thread pitch of 2.5mm, and a length of 50mm. Its shoulder measures 24mm in length and adheres to ISO 7379 standards. The class 12.9 steel construction provides high tensile strength, making it suitable for demanding applications. This type of shoulder screw is ideal for use in machinery, electrical equipment, and automotive applications, ensuring secure fastening and reliable performance.
  • Question: What are the common applications for shoulder screws?

    Answer: Shoulder screws are commonly used in applications requiring precise spacing and alignment, such as in automotive assemblies, machinery, and even in furniture construction. The shoulder provides a defined bearing surface, allowing for smooth rotation or sliding of components. For instance, they are often used in jigs or fixtures where components must maintain specific distances from each other. This functionality is key for various engineering and manufacturing processes, ensuring effectiveness in critical assemblies.
  • Question: What does Class 12.9 indicate for shoulder screws?

    Answer: Class 12.9 indicates a high tensile strength rating for shoulder screws, allowing for substantial load-bearing capabilities. This classification ensures the screw can withstand significant forces, making it suitable for heavy-duty applications in industrial settings. The strength and durability of Class 12.9 steel make these screws a preferred choice among engineers and designers for critical components that must endure harsh conditions and mechanical stress.
  • Question: Why choose ISO 7379 standards for shoulder screws?

    Answer: ISO 7379 standards provide specific guidelines for the manufacture and quality of shoulder screws, ensuring uniformity and reliability in their dimensions and performance. By adhering to these standards, users can expect consistent quality, which is crucial in precision applications where components must fit together perfectly. This ensures compliance with international quality standards, which is essential for manufacturers and industries relying on dependable and standardized fasteners in their designs.
  • Question: How do I install M20 shoulder screws?

    Answer: Installing M20 shoulder screws can be done using a hex socket wrench that fits the screw head. First, align the screw in the pre-drilled hole, ensuring the shoulder rests against the surface of the material for optimal support. Gradually tighten the screw until secure but avoid overtightening as this may cause damage. This method is commonly used in assembling machine parts, ensuring rigidity and stability in various engineering contexts.
  • Question: What materials are compatible with M20 shoulder screws?

    Answer: M20 shoulder screws can be used with a variety of materials, including metal, plastics, and wood. Since the shoulder allows for a smooth surface contact, it can be applied in mixed material assemblies, effectively preventing wear and providing a stable joint. For example, in creating machinery with plastic housings, the shoulder screw will maintain firm fastening without risking damage to the softer material, facilitating reliable performance in diverse applications.
  • Question: Can M20 shoulder screws be reused?

    Answer: Yes, M20 shoulder screws can often be reused if they show no signs of damage, such as stripped threads or deformation. When reusing, ensure the mating surfaces are clean and free from debris. This practice is common in prototyping and testing scenarios where components might be frequently disassembled and reassembled. Reusing shoulder screws can contribute to sustainable practices in manufacturing by minimizing waste and reducing the need for additional fasteners.
  • Question: What advantages does a hex socket drive provide?

    Answer: The hex socket drive offers enhanced grip and reduces slippage during installation compared to traditional screwdriver options. This design allows for higher torque to be applied, making it easier to tighten or loosen screws securely. Commonly used in mechanical assembly, the hex socket feature is especially beneficial in confined spaces where access may be limited, providing versatility and efficiency in various applications.
  • Question: Are shoulder screws available in different materials?

    Answer: Yes, shoulder screws are available in various materials, including stainless steel, brass, and nylon, catering to different application needs. Depending on the environment and load requirements, users can select materials that offer corrosion resistance, conductivity, or weight savings. For example, stainless steel shoulder screws are perfect for outdoor applications due to their resistance to corrosion, while nylon screws are ideal for lightweight applications where electrical isolation is needed.
  • Question: Where can I buy 1 pcs M20-2.5 X 50mm Shoulder Screws in Australia?

    Answer: You can purchase 1 pcs M20-2.5 X 50mm Shoulder Screws from Ubuy.
