Tables below left and right and over the next four pages list part numbers of all mandrels and mandrel follower springs available per
fastener or group of fasteners, i.e. for Chobert
While fastener sizes are always shown in their specified units, each table has been produced twice to offer dimensions in imperial units
on the left-hand page then in metric units on the right-hand page. These 'Mandrel Selection' tables cross-reference with the 'Nose Jaw
Selection' tables on pages 14-15 through the 'Ref. Nº' column.
It is the diameter of the head at the end of a mandrel which when pulled through controls the expansion of the fastener body.
While there are different head shapes to suit different types of fasteners (see illustration on page 19), progressive head sizes are
needed to reflect manufacturing tolerances on the diameter of the hole in your application so that the fastener always expands
sufficiently to fill the hole.
Too large a mandrel head would overstress the mandrel and mandrels which fail during use could forcibly exit the tool.
Selection tables are arranged into four 'mandrel size' sections, ranging from 'standard' to '3rd oversize', each being colour coded as
per the end of the mandrel heads themselves.
