Understanding #10-24 Screw Size
The #10-24 screw size is a standardized measurement that indicates two key features: the diameter and the thread count. The “#10” refers to the screw’s diameter, which is approximately 0.19 inches, while “24” signifies that there are 24 threads per inch (TPI). This combination makes #10-24 screws versatile and compatible with various nuts and pre-threaded holes.
Types of #10-24 Screws
Stainless Steel Screws
Stainless steel #10-24 screws, particularly those made from 18-8 (304) grade stainless steel, are known for their durability and corrosion resistance. These screws are ideal for applications in harsh environments, making them suitable for outdoor use and in industries like automotive and aerospace.
Zinc-Plated Screws
Zinc-plated #10-24 screws offer moderate corrosion resistance and are commonly used in general assembly applications. Their attractive finish makes them a popular choice for projects where aesthetics are essential. They are often seen in electrical enclosures and furniture assembly.
Brass Screws
Brass #10-24 screws are primarily used in decorative applications. They are non-magnetic and resistant to corrosion, which makes them suitable for electrical connections. However, their mechanical strength is lower compared to stainless steel and zinc-plated options.
Plastic Screws
Though less common, plastic #10-24 screws are used in lightweight applications. They provide a non-conductive fastening solution ideal for electronics and other sensitive equipment.
Head Styles of #10-24 Screws
Phillips Pan Head
The Phillips pan head design offers a larger bearing surface and a finished appearance. This head style is commonly used in various applications, providing a secure grip for a Phillips screwdriver.
Phillips Flat Head
Flat head screws are designed to sit flush with the surface. They are ideal for applications requiring a smooth finish, such as in cabinetry and trim work.
Hex Head
Hex head screws offer a robust fastening solution, particularly in applications requiring high torque. They are often used in machinery and automotive assemblies.
Applications of #10-24 Screws
Machinery and Equipment Assembly
The robust nature of #10-24 screws makes them ideal for fastening metal parts in machinery and equipment. Their strength ensures secure connections, which is crucial for operational safety.
Electronics
In electronics, #10-24 screws are used for securing components within devices. Their non-corrosive properties, especially in stainless steel and brass materials, enhance the longevity of electronic products.
Home Improvement
Home improvement projects often utilize #10-24 screws for assembling furniture, cabinetry, and fixtures. The variety of materials and head styles available makes them versatile for different applications.
Outdoor Applications
Zinc-plated and stainless steel #10-24 screws are commonly used in outdoor applications due to their corrosion resistance. They are used in fencing, decking, and other outdoor structures where exposure to the elements is common.
Technical Features of #10-24 Screws
| Feature | Value |
|---|---|
| Diameter | 0.19 inches |
| Threads per Inch (TPI) | 24 |
| Standard Head Size | Varies by head style |
| Material Options | Stainless Steel, Zinc-Plated Steel, Brass, Plastic |
| Common Drive Types | Phillips, Hex |
