Can I use 7/8 instead of 22mm?
The short answer is: it depends. The choice between using a 78mm or 22mm diameter component can have important implications, and should be carefully considered based on the specific requirements of your project. In this article, we'll explore the key factors to take into account when making this decision.
Understanding the Differences
The 22mm and 78mm diameters refer to common sizes used for various components, such as switches, buttons, and other hardware. The primary difference between the two is the physical size and the corresponding space requirements within the design.
A 22mm component is generally smaller and more compact, making it suitable for applications with limited space or where a more discreet appearance is desired. Conversely, a 78mm component is larger and may be better suited for applications where visibility, ease of use, or accessibility are more important factors.
Factors to Consider
When deciding between a 78mm or 22mm component, you should consider the following factors:
- Physical Space: Evaluate the available space in your design and determine which size will fit best without compromising other components or the overall layout.
- Visibility and Accessibility: Consider whether the larger 78mm size would improve visibility and make the component easier to interact with, especially for users with dexterity or visual impairments.
- Aesthetics and Design: Assess how the different sizes would impact the overall aesthetic and design of your product. The larger 78mm component may be more visually prominent, which could be desirable or undesirable depending on your design goals.
- Compatibility and Interoperability: Ensure that the chosen component size is compatible with any existing or planned systems, interfaces, or enclosures in your design.
- Cost and Availability: Consider the cost and availability of the different component sizes, as this may be a factor in your decision-making process.
Ultimately, the decision to use a 78mm or 22mm component will depend on the specific requirements and constraints of your project. It's important to carefully evaluate the trade-offs and choose the size that best meets your design goals and user needs.
What's equivalent to a 22mm socket?
A 22mm socket is a metric size, and its closest equivalent in standard (SAE) sockets is 7/8 inch. While the 7/8" socket may fit, it's a very close approximation, as 22mm is equal to about 0.866 inches, while 7/8 inch is exactly 0.875 inches.
Key comparisons
- 22mm vs. 7/8 inch: A 22mm socket is slightly smaller than a 7/8" socket, so the 7/8" socket might feel a bit loose on a 22mm fastener, or the 22mm socket might be a very snug fit on a 7/8" fastener.
- Precision: For best results, it's recommended to use the correct measurement (metric or standard) for the fastener you are working with.
- Interchangeability: Due to the close proximity in size, these sockets are often used interchangeably in situations where precision is not critical, notes PEHEL Hydraulic.
Is 7/8 of an inch equal to 22 mm?
No, 7/87 / 87/8 inch is not the exact same as $22$mm, but they are very close and often used interchangeably for certain applications. Specifically, 7/87 / 87/8 inch is approximately $22.23$mm, while $22$mm is equal to approximately 0.8660.8660.866 inches.
| Measurement | Decimal Value |
|---|---|
| 7/87 / 87/8 inch | 0.8750.8750.875 inches |
| $22$mm | 0.8660.8660.866 inches |

- In practice: For many applications, like lug nuts, a 7/87 / 87/8 inch socket can be used on a $22$mm nut, though it may be slightly loose, and a $22$mm socket may be snug on a 7/87 / 87/8 inch nut.
- Best practice: If exact fit is critical, using the precise tool for the job is recommended, as the slight difference could be an issue in some cases.
Can I use a 7/8 instead of 22mm?
Yes, a 7/8 inch socket will fit a 22mm lug nut, although it may be slightly loose because 7/8 inch (22.2322.2322.23 mm) is marginally larger than 22mm (0.230.230.23 mm difference). Using the correct 22mm socket is ideal to prevent stripping the nut, especially if there is any corrosion.
- Why it fits: 7/87 / 87/8 inch is approximately 22.2322.2322.23 mm, which is only a small difference from 22mm.
- Potential issues: The slight looseness of the 7/8" socket could cause it to strip the lug nut, especially if the nut is already worn or damaged.
- Best practice: It is always best to use the 22mm socket if you have it to ensure the most secure and precise fit and to avoid damaging the lug nut.
- Alternative: If a 22mm socket is unavailable, a 7/8" socket will likely work, but be prepared for it to be a bit loose.
What size is closest to 22 mm?
The closest standard size to 22mm is 7/8 inch. While 22mm is exactly 0.8660.8660.866 inches, the 7/8 inch standard is 0.8750.8750.875 inches, making it the closest fractional size and a common alternative for tools like wrenches and sockets.
- Conversion: 22mm is equal to approximately 0.8660.8660.866 inches.
- Standard Size: 7/8 inch is equal to 0.8750.8750.875 inches.
- Proximity: 7/8 inch is the closest standard fractional size, with only a small difference of about 0.0090.0090.009 inches.
- Interchangeability: While 7/8 inch tools may fit a 22mm fastener, a 22mm tool might be a snugger fit on a 7/8 inch fastener, as shown in this Amazon.com forum, says this Amazon.com forum.
