What are Cheese Head Screws?<\/strong><\/h3>\n

A Cheese Head Screw is a type of machine screw or self-tapping screw characterized by its distinctive head style. The head is cylindrical with a flat top and a flat bearing surface underneath, featuring a slightly rounded chamfer at the edge where the head meets the shaft. The height of the head is approximately half of its diameter, giving it a low-profile, “cheese-wheel” appearance, which is where it gets its name.<\/p>\n

The primary function of this head style is to provide a higher bearing surface and a larger head diameter compared to a pan head, while maintaining a lower profile than a fillister head. Cheese Head Screws offer a good compromise between clearance and the ability to apply higher torque without the driver camming out, typically using a cross recess (Phillips or Pozi drive) or a slotted drive.<\/p>\n

Materials<\/strong><\/h3>\n

Cheese head screws are manufactured from a variety of materials to suit different environmental and strength requirements:<\/p>\n

    \n
  • \n

    Steel (Low Carbon Steel):<\/strong>\u00a0The most common and economical material. Offers good strength for general-purpose applications.<\/p>\n<\/li>\n

  • \n

    Stainless Steel (Grades 304 and 316):<\/strong>\u00a0Provides excellent corrosion resistance. Grade 316 offers superior resistance to salts and chemicals, making it ideal for marine and food-grade applications.<\/p>\n<\/li>\n

  • \n

    Brass:<\/strong>\u00a0Offers good corrosion resistance, especially in marine environments, and is non-magnetic and electrically conductive.<\/p>\n<\/li>\n

  • \n

    Aluminum:<\/strong>\u00a0Used for its very light weight and good corrosion resistance. It is softer and weaker than steel.<\/p>\n<\/li>\n

  • \n

    Nylon \/ Plastic:<\/strong>\u00a0Used in non-conductive, non-magnetic, and lightweight applications where corrosion is not a concern.<\/p>\n<\/li>\n<\/ul>\n

    Surface Treatments<\/strong><\/h3>\n

    Surface treatments of Cheese Head Screws are applied to enhance corrosion resistance, appearance, and sometimes lubricity.<\/p>\n

      \n
    • \n

      Zinc Plating (Electroplating):<\/strong>\u00a0The most common finish for steel screws. Provides a shiny silver appearance and good corrosion resistance. Often followed by a clear or blue chromate conversion coating for enhanced protection (creating a finish known as “clear zinc” or “blue zinc”).<\/p>\n<\/li>\n

    • \n

      Black Oxide:<\/strong>\u00a0Provides a matte black finish that offers mild corrosion resistance and reduces light glare. It is a conversion coating, not a plating.<\/p>\n<\/li>\n

    • \n

      Nickel Plating:<\/strong>\u00a0Offers a hard, smooth, and corrosion-resistant surface with a shiny silver appearance.<\/p>\n<\/li>\n

    • \n

      Phosphate Coating:<\/strong>\u00a0Mainly used as a base for paint or oil retention, providing good corrosion resistance when oiled.<\/p>\n<\/li>\n

    • \n

      Passivation:<\/strong>\u00a0A chemical process for stainless steel that removes free iron from the surface, enhancing its natural corrosion resistance without altering its appearance significantly.<\/p>\n<\/li>\n<\/ul>\n

      • \n

        Head Diameter:<\/strong>\u00a0Larger than most pan heads, providing a greater bearing surface.<\/p>\n<\/li>\n

      • \n

        Standards:<\/strong>\u00a0Can be manufactured to various international standards like ISO (International), DIN (German), or ANSI\/ASME (American).<\/p>\n<\/li>\n<\/ul>\n

        Application Fields of Cheese Head Screws<\/strong><\/h3>\n

        Cheese head screws are versatile and used in many industries where a low-profile head with good torque capability is needed:<\/p>\n

          \n
        • \n

          Electronics & Electrical Enclosures:<\/strong>\u00a0Securing panels and components in computers, control boxes, and appliances.<\/p>\n<\/li>\n

        • \n

          Automotive Interiors:<\/strong>\u00a0Assembling interior trim panels, dashboards, and electrical components where a low-profile head is desirable.<\/p>\n<\/li>\n

        • \n

          General Manufacturing & Machinery:<\/strong>\u00a0Used in a wide array of products for general assembly.<\/p>\n<\/li>\n

        • \n

          Furniture Assembly:<\/strong>\u00a0Particularly in older or industrial-style furniture.<\/p>\n<\/li>\n

        • \n

          Plastics Assembly:<\/strong>\u00a0Self-tapping cheese head screws are often used to join plastic components.<\/p>\n<\/li>\n<\/ul>\n

          \n

          An Excellent Case: Securing an Automotive Dashboard Control Unit<\/strong><\/h3>\n

          Scenario:<\/strong>\u00a0An automotive engineer is designing the mounting for a critical electronic control unit (ECU) behind the dashboard of a new car model. This ECU must be securely fastened to a metal bracket to prevent vibration-induced failure, but space is extremely limited. The screw head must not protrude too far to avoid interfering with other dashboard components. The assembly will be done on a fast-moving production line, requiring a drive system that allows for efficient installation.<\/p>\n

          The Problem:<\/strong>\u00a0Using a standard\u00a0pan head screw<\/strong>\u00a0might protrude too much and cause interference. A\u00a0flat head (countersunk) screw<\/strong>\u00a0would be flush but requires a precise conical hole, which adds cost and complexity to the bracket and doesn’t handle vibrational loosening as well. The screw needs to be installable quickly with a power driver.<\/p>\n

          The Solution:<\/strong>\u00a0The engineer specifies\u00a0Phillips drive, cheese head screws<\/strong>\u00a0(e.g., M5 x 16mm) made from\u00a0stainless steel (A2-70 grade)<\/strong>\u00a0with a\u00a0blue zinc chromate finish<\/strong>\u00a0for corrosion resistance.<\/p>\n

            \n

            Why it Works Perfectly:<\/strong><\/p>\n

              \n
            1. \n

              Low Profile:<\/strong>\u00a0The cheese head’s lower height provides the necessary clearance in the tight space behind the dashboard, preventing interference with overlying components.<\/p>\n<\/li>\n

            2. \n

              High Torque & Secure Drive:<\/strong>\u00a0The Phillips drive allows for rapid installation on the assembly line. The larger head diameter and deeper drive recess compared to a pan head provide a greater bearing surface and reduce the risk of the driver bit camming out and stripping the head during high-torque installation.<\/p>\n<\/li>\n

            3. \n

              Vibration Resistance:<\/strong>\u00a0The wide, flat bearing surface under the head distributes clamp load evenly and, when used with a split lock washer, effectively resists loosening from vehicle vibration.<\/p>\n<\/li>\n

            4. \n

              Durability:<\/strong>\u00a0The stainless steel material and zinc plating ensure the screw will not corrode from humidity or temperature changes inside the vehicle over its 15+ year lifespan.<\/p>\n<\/li>\n<\/ol>\n<\/li>\n<\/ul>\n

              Outcome:<\/strong>\u00a0The ECU is mounted securely and reliably for the entire life of the vehicle. The production line achieves fast and error-free installation with minimal stripped screw heads, reducing assembly time and cost. This simple, cost-effective component choice ensures the critical electronic unit functions perfectly without failure due to a loose mount, directly contributing to the vehicle’s quality and reliability.<\/p>","protected":false},"excerpt":{"rendered":"
