What can I use instead of a 5/16 drill bit?

5/16 converts to 10/32. Assuming your bit set is that granular, the next larger size is 11/32, and the next smallest size is 9/32. Those aren’t necessarily common sizes, however. The next size up in x/16 would be 6/16, which is 3/8.

What size hole do you drill for a 5/16 lag bolt?

For a 5/16-in. lag bolt, that works out to be about 7/32 in. The unscientific approach that I’ve always used is just lining up drill bits with the threaded part of the lag to find the one that is closest to the minor diameter. When in doubt, err on the smaller side.

How do I know what size my drill bit is?

Typical drill bits have markings somewhere on the shank above the threads. It’s small, but it usually has the drill-bit diameter stamped into the metal; the number is written in fractions. For example, the markings may read: 1/4-inch, 3/6-inch or 25/32.

Should pilot hole be smaller than screw?

As a general rule of thumb, your pilot hole should be slightly smaller than the diameter of your screw. This will remove as much material as possible, which will reduce the likelihood of splitting, but will still leave enough material for the screw’s threads to grip into.

What size are lag bolts?

Typically, lag bolt sizes range from 1/4″ to 3/4″ in diameter, and lengths span from about 1″ to 16″. Although 7/16″ is detailed in the ASME standard, that size is not commonly available. Measure length from under the head to the threaded end of the bolt. The size of the head varies with the size of the lag bolt.
