What size stub would be used for a 3/4" bolt hole?

To determine the appropriate size stub for a 3/4" bolt hole, it’s essential to understand that the stub size should accommodate the bolt diameter, enabling a secure fit. Typically, the stub size will be slightly larger than the bolt diameter to ensure there is enough room for the bolt to fit comfortably and allow for any necessary adjustments or tolerances.

In this case, a 3/4" bolt hole, which has a diameter of 0.75 inches, would generally use a stub that slightly exceeds this dimension. The 5/8 size is too small, and while 7/8 is larger than needed, the next step is to note that the correct fit for a 3/4" hole would typically be 1/8" larger to ensure a snug but fitting joint without being overly loose or too tight to work with. The 5/8 stub size does not permit enough clearance for that 3/4 bolt and is therefore not suitable.

This understanding leads to the conclusion that the 7/8 size is the best choice, as it provides adequate allowance for the bolt to be inserted and positioned without hindrance. Thus, the stub size of 7/8 is appropriate for a 3/4
