Sold by the dozen, the Arizona glue-on Z Nock uses a snap-on design for a positive string fit, resulting in a smooth release from the bowstring. The Z Nock has a large finger pinch area, allowing you to nock your arrows quickly and easily. The angled throat design keeps the nock on the bowstring at any string angle and the thin base blends perfectly to the arrow shaft. Available in 11/32, 5/16, 9/32 and 1/4 sizes in a selection of colours.
