I need help identifying a bolt thread. The hardware store is closed and the only tool I have is a ruler.

1. Measure the diameter of the bolt. This will give you an idea of the size of the bolt, which can help you identify the thread.

2. Count the number of threads per inch. You can do this by measuring the distance between two threads and then dividing that by the overall length of the bolt. This will give you the number of threads per inch.

3. Look for any markings or branding on the bolt that could give you additional information about the type of thread.

4. Check the pitch of the threads. The pitch is the distance between two threads and is usually measured in millimeters. To measure the pitch, you can use a ruler to measure the distance between two threads, then divide that number by the number of threads per inch.

5. Look for other physical characteristics of the bolt. For example, some bolts have a square or hexagonal head, while others have a rounded head. This information can help you identify the thread.

6. Use online resources to help identify the thread. There are several websites and forums dedicated to hardware and tools that can provide information about different bolt threads.

7. If all else fails, bring the bolt to a hardware store when it reopens and ask for assistance from a knowledgeable employee.

Is it possible to do without ruler?

Yes, it is possible to identify a bolt thread without a ruler. You can use a thread gauge, which is a tool specifically designed for measuring threads. If you don't have a thread gauge, you can try using a caliper or a micrometer, which are both tools that can measure small distances. Additionally, you can try using a magnifying glass to get a closer look at the threads and look for any markings or branding that could give you additional information.
