For a 1 1/4" bolt hole, what is the appropriate size stub?

The appropriate size stub for a 1 1/4" bolt hole is 1 1/8". This size is selected based on the need for a snug fit that allows for sufficient engagement of the bolt within the hole without excess play. The 1 1/8" dimension is slightly smaller than the bolt hole, ensuring that the stub can fit securely while still accommodating any tolerances needed for proper assembly.

When selecting stub sizes, it is essential to consider the diameter of the bolt and the clearance requirements for installation. Stubs that are too large may lead to difficulties in inserting the bolt, while those that are too small may not provide the necessary support for the joint. By using a 1 1/8" stub for a 1 1/4" hole, you achieve an optimal balance between security and accessibility for fastening.
