Thereof, How do you measure a screw hole?
If you have to buy the nuts too, then that’s easy to match the bolts when you find them. You can measure the hole with a tape measure, as long as you are VERY accurate. Measure at the widest part of the circle and get it to the closest millimeter if you can.
Also to know is, What size hole do you drill for a number 10 screw?

Also, How big should a pilot hole be for a screw?
For most hardwoods, the pilot hole should be at least as large as the screw’s minor diameter. If the screw has deep threads, or the wood is very hard, the pilot hole should be another 1/64-in. larger than the minor diameter. For softer woods, the pilot hole can be 1/64-in.

What is the diameter of a #6 screw?
Do you drill a hole the same size as the screw?
If you are creating a pilot hole for a nail, the right drill bit is slightly smaller than the nail’s shank. If you are creating a pilot hole for a screw, the drill bit should be the same size as the body of the screw—not including the threads.
What is a #6 screw?
This means it’s a #6 diameter, with 32 threads per inch (almost double the normal thread count as a standard wood screw) and an inch and a half long. When the middle number is absent (6 x 1 1/2″), the screw has the “normal” number of threads per inch for that size and type of screw (for #6 wood screws that’s 18).
Should a drill bit be the same size as the screw?
The drill bit should be the same size as the shaft of the screw without accounting for the threads. To do this, simply line up a screw side by side with the drill bit. If they’re the same size, then you’re good to go. You can also look for the measurements labeled on most bits and screws.

What size hole do I drill for a 10 sheet metal screw?
Your pilot-hole drill-bit size will depend on the size of your sheet-metal screw. A size-4 screw should have a pilot-hole drill size of 3/32 inches; size 6, 7/64 inches; size 8, 1/8 inches; size 10, 9/64 inches; size 12, 5/32 inches; size 14-1/4 inches, 3/16 inches; and 5/16 inches, 1/4 inches.
How much smaller should a drill bit be than the screw?
If you are creating a pilot hole for a nail, the right drill bit is slightly smaller than the nail’s shank. If you are creating a pilot hole for a screw, the drill bit should be the same size as the body of the screw—not including the threads.
What is the diameter of a #6 machine screw?
How do you know what size hole to drill?
Hold the shaft of the drill bit up in front of the screw. You should only be able to see the threads of the screw (and maybe a bit of the screw). If you can’t see the threads the drill bit is too big. If you can see too much of the screw, the bit is too small.
