Socket Head Cap Screws

Socket head cap screws are a type of fastener known for their cylindrical head and internal hexagonal drive, which allows for easy tightening with a hex key or Allen wrench. Here are some key features and specifications of socket head cap screws:

  1. High Strength: Typically made from high-strength materials like alloy steel, these screws can handle significant loads and are ideal for demanding applications.
  2. Compact Design: The socket head design provides a lower profile compared to traditional hex heads, making them suitable for applications with limited space.
  3. Ease of Use: The internal hex drive allows for better torque application and can be used in tighter spaces where a traditional wrench may not fit.
  4. Versatile Applications: Commonly used in machinery, automotive, aerospace, and construction industries due to their strength and reliability.
  5. Variety of Finishes: Available in various finishes, such as black oxide, zinc plating, or plain, to provide different levels of corrosion resistance and aesthetic appeal.
  1. Material: Usually made from alloy steel (e.g., AISI 4140 or 4130), stainless steel (e.g., A2 or A4), or other materials based on application requirements.
  2. Diameter: Available in a range of diameters, commonly from 1/4 inch up to several inches.
  3. Length: Offered in various lengths, typically specified in increments.
  4. Thread Types: Can be coarse or fine threads, depending on the application.
  5. Head Height: The height of the head can vary, affecting the overall design and fit.
