Rack bolt screws are made from various materials, each chosen to enhance performance in specific applications.
Mild steel is commonly used for rack bolt screws due to its affordability and ease of manufacturing, providing adequate strength for many general-purpose applications. However, it can be susceptible to corrosion, so it is often coated with protective finishes.
Stainless steel is popular for its excellent corrosion resistance and strength, making it ideal for moist or harsh environments. It’s also preferred in food processing and medical equipment for its hygienic properties.
Plastic rack bolt screws are used where electrical insulation or chemical resistance is needed. They are lightweight and suitable for low-stress environments, although not as strong as metal screws.
Applying various finishes can significantly enhance the durability and performance of rack bolt screws.
Zinc plating coats screws with a thin layer of zinc, enhancing their corrosion resistance, making them suitable for indoor use where exposure to moisture or chemicals is minimal.
Hot dip galvanizing involves dipping screws into molten zinc, creating a thick, durable protective layer. These screws are highly resistant to corrosion, ideal for outdoor or moist environments.
Nickel plating provides a hard, smooth finish that enhances both appearance and durability, offering excellent resistance to corrosion and wear for decorative and functional applications.
Rack bolt screws come in various thread types, each designed for specific applications.
10-32 threads, with a diameter of 3/16 inches and 32 threads per inch, are commonly used in server racks and audio racks, providing a strong hold for electronic components.
12-24 threads, slightly less than 7/32 inches in diameter with 24 threads per inch, are often used in pre-threaded racks, balancing strength and ease of installation.
M6 threads are metric screws with a 6 mm diameter, commonly used in server racks from manufacturers like HP. Their metric sizing makes them versatile for international equipment.
Rack bolt screws have various head types, each offering specific benefits for installation and use.
Hex heads provide a secure grip for tools, making them easy to tighten and loosen. They are commonly used where a strong, tight fit is needed.
Other head types include flat heads, pan heads, and round heads, each designed for specific uses. Flat heads are good for countersinking, pan heads offer a low profile, and round heads provide a traditional look with easy tool access.
Rack bolt screws can be partially or fully threaded, each offering different benefits.
Partially threaded screws have a smooth shank near the head, providing extra strength and alignment for connected parts. They are useful where precise positioning is crucial.
Fully threaded screws have threads along the entire length, providing a strong hold throughout. They are ideal for applications needing maximum grip and security, such as heavy-duty data center installations.
Rack bolt screws are essential for installing sanitary fittings like wall-mounted wash basins and commodes. They provide structural support to ensure these fixtures are securely attached to walls.

Below are answers to some frequently asked questions:
A rack bolt screw is a hybrid fastener that combines characteristics of both bolts and screws. Unlike a standard screw, which typically threads into a material to hold it in place, a rack bolt screw is designed for applications requiring high strength and stability, similar to bolts. It has a threaded shaft like a screw but often engages with a rack or a series of teeth, providing a secure and stable connection. This makes it ideal for precise, heavy-duty applications, such as in sanitary fixtures, data centers, and security fittings. In contrast, a regular screw is a versatile fastener used for a wide range of lighter tasks and can create its own threads in softer materials or screw into pre-drilled holes.
Rack bolt screws are commonly made from materials such as mild steel, stainless steel, and plastic. Mild steel is often used for its high strength and durability, with finishes like zinc plating or hot dip galvanizing to enhance corrosion resistance. Stainless steel, available in grades such as SS202 and SS304, is chosen for its excellent corrosion resistance, making it ideal for applications exposed to moisture, such as sanitary fittings. Plastic rack bolt screws are used where non-conductivity or lightweight properties are needed.
To choose the right thread type for your application, you need to consider the specific requirements of the equipment and the environment in which the rack bolt screw will be used. For data center and server rack applications, the common thread types are 10-32, 12-24, and M6.
Ensure the thread type matches the pre-threaded holes in your server racks or other fixtures. Additionally, consider the material and finish of the screws to ensure they provide the necessary corrosion resistance and durability for your specific environment.
Rack bolt screws are generally not recommended for outdoor applications. Although they can be durable and may have coatings like nickel or zinc plating to enhance their resistance to corrosion, these coatings are not typically sufficient for the harsh conditions encountered outdoors. Outdoor environments expose screws to elements such as rain, temperature fluctuations, and UV radiation, which can degrade standard coatings quickly. For outdoor use, screws made from materials like stainless steel, especially those labeled as "316" or "A4," or those with heavy-duty coatings such as galvanized or ceramic, are more suitable due to their superior corrosion resistance and ability to withstand environmental stressors.
The benefits of using rack bolt screws in data centers include providing secure and stable attachment of equipment to server racks, ensuring proper organization and functionality. They facilitate the easy installation and removal of servers, network switches, and other IT equipment, enhancing efficiency. Additionally, rack bolt screws are available in various thread types, such as 10-32, 12-24, and M6, which ensures compatibility with different equipment. Their durable construction helps to maintain the integrity and security of the mounted devices, even in environments with significant vibration or movement.
To ensure the security of your door or window with rack bolts, install them in a concealed manner, typically morticed into the frame. Use a thumb turn or a splined key to operate them. Position the bolts at the top and bottom of the door or window for added security. Ensure they are made of durable materials like solid brass and match the correct size for your frame. Regularly check and maintain the bolts to keep them in good working condition.
