Figuring Size of Rivet
To use a semi-tubular rivet, choose the shank size to fit the hole
in the assembly and choose the head style that fits your application
(the bigger the head the stronger the rivet, but more expensive).

of sizes.
To figure the length, add the assembly thickness to the clinch
allowance from the table below. This number can be rounded to the
nearest 1/64" or 1/32". Typically a longer rivet would
be better than a shorter rivet.
Hole Style - Taper or Straight
New Jersey Rivet Company can produce straight hole and tapered
hole semi-tubular rivets. Tapered hole rivets give better
support during the clinching of the rivet due to the fact that the
sidewall increases in thickness as you clinch the rivet. This
means that the rivet is less likely to collapse during the clinching
of the rivet.
