Customer Questions & Answers

  • Question: What are 5/16"-18 x 5/16" set screws used for?

    Answer: 5/16"-18 x 5/16" set screws are primarily used to secure objects within a larger assembly by fitting into an unthreaded hole or onto a threaded rod. The cup point design allows for a secure grip on the mated surface, ensuring minimal movement or rotation. These screws are perfect for applications in machinery, furniture, and automotive parts where stability is crucial.
  • Question: What materials are these set screws made from?

    Answer: These set screws are made from alloy steel, known for its strength and durability. The zinc plating provides additional protection against corrosion, making them suitable for various environments, including outdoor settings. This combination of materials ensures that the screws can withstand substantial force while resisting wear, making them ideal for heavy-duty applications.
  • Question: How do I determine the correct length of a set screw for my project?

    Answer: The length of a set screw should be selected based on the application requirements and the thickness of the materials it will connect. For effective grip, the screw should extend sufficiently into the receiving part, but not so long that it protrudes excessively. A 5/16" length is suitable for many industrial and woodworking applications where securing components is vital.
  • Question: Can I use these set screws in non-metal applications?

    Answer: Yes, while 5/16"-18 set screws are typically utilized in metal applications, they can also be used in conjunction with plastic or wood components. However, care should be taken to ensure that the material can hold the set screw securely. For softer materials like wood, pre-drilling is recommended to prevent splitting.
  • Question: Are these set screws resistant to rust?

    Answer: Yes, these set screws feature a zinc plating that provides a layer of protection against rust and corrosion. This makes them suitable for applications in humid or moist environments. It's essential to note, however, that while zinc plating aids in rust resistance, prolonged exposure to harsh conditions may still require consideration of different materials or additional coatings.
  • Question: What tools do I need to install 5/16" set screws?

    Answer: To install 5/16" set screws, you typically need a hex key or Allen wrench that matches the hex socket on the top of the screws. Additionally, a screwdriver may be required for positioning. Having pliers or wrenches can be beneficial for applying the necessary torque without damaging the screw or surrounding materials.
  • Question: Are these screws suitable for high-torque applications?

    Answer: Yes, these alloy steel set screws are designed to withstand high-torque applications due to their robust construction and threading. When securely tightened, they offer reliable performance and can prevent loosening, making them ideal for machinery and equipment where maintaining alignment and stability is essential.
  • Question: What is the significance of the 'cup point' design?

    Answer: The 'cup point' design of set screws helps in providing a concentrated point of contact with the mated surface, enhancing grip and stability. This design minimizes the risk of slippage and is particularly useful in securing axles or gears, where vibration can lead to loosening. It creates a permanent or semi-permanent bond between components.
  • Question: Can I find these set screws in bulk if I need more than a 100 pack?

    Answer: Yes, many suppliers provide bulk purchasing options for set screws, making it convenient for industrial applications or large-scale projects. Buying in larger quantities can often lead to cost savings and ensures you have an adequate supply for ongoing or future projects.
  • Question: Where can I buy 5/16"-18 x 5/16" set screws, cup point, alloy steel, zinc plated, 100 pack?

    Answer: You can find 5/16"-18 x 5/16" set screws, cup point, alloy steel, zinc plated, 100 pack on Ubuy in Brunei. Ubuy provides a convenient online platform for sourcing high-quality hardware, ensuring a reliable shopping experience with extensive product variety.
