In combination with a bow having a riser with a generally flat sided cut-away part having an internally threaded passage extending through it, an arrow rest spacer has a shaft with a channel extending axially from the outer end of the shaft, the channel being open at the outer end of the shaft and along at least one axial side of the shaft. A wall of the channel is thicker at an inner part of the channel than it is at the outer end of the channel, to form a shallower channel area in the inner part. The shaft is proportioned to fit closely but slideably in the threaded passage. The shaft is made of a material that is rigid enough to support the arrow rest in use, but elastic enough to permit a threaded plug to form threads in it as it is screwed in, and to expand as the plug moves into the shallower part of the channel. Preferrably, the bow passage is internally threaded, and an externally threaded plug, the threads of which are of the same pitch as the internal threads of the threaded passage, is of a diameter to be received into the channel at its outer end and at the same time to engage the threads of the passage.
