The 17 in 1716 is the outside diameter in 1/64ths of an inch, so the arrow
is 17/64ths in diam. 5/16 is 20/64th so it is to big, 9/32 is 18/64ths. So
for the 1716 I would get 1/4= 16/64ths, 1816 and 1916 get 9/32,
Any glue on nock will fit the shafts with tapered ends. I do like these
bohning nocks. But it is all personal preference, and application. I prefer
a nock that has a large opening because I use a very thick serving on my
string. I like the large index tab on this nock.
