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). Click here for a chart 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.
