Do all knobs use the same size screw? The short answer is no. The size of the screw you need for a knob depends on several factors, including the type of knob, its size, and the material it is made from.
For example, cabinet knobs typically come with M4 or M5 size screws, with M4 being the most common. If the knob is made from a softer material, such as resin or ceramic, an M4 screw is usually sufficient. However, if the knob is made from a harder material, such as metal, an M5 screw may be required to provide more support.
In addition, the length of the screw is important and can vary by manufacturer. For interior door knobs, #8-32 screws are commonly used, but the length can differ depending on the thickness of the door. It's recommended to measure the door thickness and add 1/4 to determine the appropriate screw length.

Cabinet knobs come with M4 and M5 screws, with M4 being the most common
Cabinet knobs typically come with M4 and M5 screws, with M4 being the most common size. M4 screws have a 4mm thread and are suitable for most cabinet handles and knobs. They are available in a range of lengths, from 8mm to 55mm, to accommodate different door thicknesses. M5 screws, on the other hand, are less common and tend to be used for heavier knobs or those requiring longer screws.
While there is no universal standard for cabinet knob screw diameters, M4 screws are the most prevalent, and it is rare to encounter issues with screw diameters not matching. Most new knobs or hinges will come with screws that fit the standard knob screw holes. However, it is always a good idea to bring an old screw to the store when purchasing new knobs to ensure a perfect match.
The length of the screw required depends on the thickness of the cabinet door or drawer. The general rule is to measure the door thickness and add a quarter of an inch for the screw to fit securely into the knob. It is recommended to not use a screw more than three-eighths of an inch longer, as it may not screw in far enough. Some hardware may even come with two sets of screws to accommodate different door thicknesses.
When replacing cabinet knobs, it is essential to consider the length and diameter of the screws. While most knobs come with standard M4 screws, there may be variations in screw length, and in some cases, the diameter may be larger, requiring you to drill larger holes in the cabinets. Therefore, it is advisable to have the old screws or knobs with you when purchasing new ones to ensure compatibility.

M4 screws are used for knobs made from softer materials like resin or ceramic
When it comes to knobs, it's important to select the right type and size of screw to ensure a secure fit. While there is no universal screw size that fits all knobs, M4 screws are commonly used for knobs made from softer materials like resin or ceramic.
M4 screws have a diameter of 4mm and are often used for smaller knobs or those made from softer materials. The smaller thread size of M4 screws means they can be easily inserted into materials like resin or ceramic without the need for extensive drilling or the risk of cracking. This makes them a popular choice for knobs made from these materials.
Resin knobs, for example, are known for their lightweight and decorative designs. By using M4 screws, manufacturers can ensure that the knob is securely attached without compromising the integrity of the resin. Similarly, ceramic knobs, which are often used for their aesthetic appeal, can be installed with M4 screws to avoid any damage to the ceramic material during the installation process.
Additionally, M4 screws are widely available and can be found at most hardware stores or online retailers. They are also commonly used in various applications beyond knobs, making them a versatile option for hobbyists and professionals alike. It's always a good idea to check the specific requirements of your knob before purchasing screws, as the length and thread type may vary slightly depending on the knob's design.

M5 screws are used for knobs made from harder materials like metal
When it comes to screws for knobs, it's important to note that while the diameter of the screw holes in knobs is generally standard, the length of the screws can vary depending on the application. The most common screw size for knobs is the #8-32 screw, which has a diameter of approximately 0.16 inches or 4 mm. This is the standard size that comes with most new knobs and hinges, and it typically fits without any issues.
However, in some cases, the screw size may differ, especially if the knobs are heavier or made from harder materials like metal. In such cases, M5 screws are often used. M5 screws have a diameter of 5 mm, which is larger than the standard #8-32 screw. If you're replacing old knobs with new ones that require M5 screws, you may need to drill out larger holes in your cabinets or furniture to accommodate the larger screw size.
The length of the screw also plays a crucial role. The standard length for screws provided with knobs is typically 1 inch. However, if you're using these screws for drawers instead of doors, they may be too short. In such cases, you can measure the thickness of your drawer front and add 1/4 inch to determine the appropriate screw length. It's important not to use a screw that is more than 3/8 inch longer, as it may not screw in properly.
When dealing with knobs made from harder materials like metal, M5 screws are often the preferred choice due to their larger diameter and ability to provide a more secure hold. It's always a good idea to check the screw size required for your specific knob application and ensure that the screws you purchase are of the appropriate length and diameter.

#8 or #10 screws are recommended for cabinets
When installing cabinet knobs, it is important to use the right type and size of screws to ensure a secure fit. While there is no standard screw size for cabinet knobs, #8 or #10 screws are commonly recommended for this purpose. These screws typically have a larger diameter head, providing a greater contact surface between the screw and the cabinet, resulting in increased holding power.
The specific screw size required may vary depending on factors such as the weight of the knob, the type of cabinet material, and the thickness of the cabinet door or drawer front. It is always a good idea to measure the thickness of your cabinet door or drawer front and select a screw that is long enough to provide adequate support. For example, if your cabinet door is 3/4" thick, you may need a 1" screw that leaves about 1/4" for screwing into the knob.
When choosing screws for cabinet knobs, it is also important to consider the thread size. Most hardware manufactured in the last 20 years uses an 8-32 thread size. However, it is always best to check the specific requirements of your cabinet knobs and select screws that match those specifications.
Additionally, it is worth noting that some handmade or unusual cabinet knobs may require bigger diameter screws and holes. In such cases, it is essential to pre-drill the holes to ensure a proper fit. Taking the old knob or the new one to a hardware store can help you find the exact screws you need.

#8-32 screws are commonly used for doorknobs
When replacing a doorknob, it is important to note that the length of the screw is also important and can vary by manufacturer. If you are unable to find the exact screw that fits your doorknob, it is recommended to take the knob to a hardware store to find a matching screw. It is also important to ensure that the replacement screw is not too long, as it may bottom out before the handle is tightened.
#8-32 screws are typically available in various lengths and materials, such as zinc and stainless steel. They are commonly used for knobs and pulls, and the length of the screw will depend on the thickness of the door or drawer.
While #8-32 is the most common size, there may be some variations in screw sizes for doorknobs, especially for older or antique doorknobs. In such cases, it may be necessary to adjust the size of the hole or find a suitable replacement knob.
