The reamer bolt is a kind of hardware. Its function is to connect the front thread and position the rear thread without thread.

For bolted connections with reamed holes, the diameter of the screw part and the basic size of its hole are the same, that is, a transition fit (not a clearance fit). When there is relative sliding between the connected parts, the bolt itself is relied on to prevent it from moving, so only a small preload is required.
