Semi Tubular rivets are set by deforming the hole
formed in the end of the shank of the rivet. This can be done using
a hand held punch or in high volume applications, fully automatically
using a purpose built riveting machine. The correct specification
of the rivet is the key to a successful application. The table below
indicates the main dimensions and gives a guide to specifying the
length of the rivet.

Example:
3mm diameter rivet to fix a combined thickness of 12mm in steel
would require a rivet 12mm underhead plus 2.06mm riveting allowance
giving a length of 14.06mm. We would be happy to advise
you directly either by Telephone, Fax or e-mail.
