because of improper fit, interference, or lack of a center
hole.
A flange plate in many cases adds value because it
aids in more effective centering than a collet alone. This
statement is true for many wheels including hub centric
wheels. That is why a flange plate and back cone may be
more accurate and repeatable, regardless of whether the
wheel is lug centric or hub centric.
Using the Pressure Ring and Spacers
Pressure Ring
The pressure ring clips on to the wing nut. It is used in
lieu of the clamping cup.
It may also be used in place of a clamping cup if space is
limited between the wheel and the end of the spindle.
The pressure ring should be used to prevent the wing nut
from directly contacting an adaptor or a collet. It will act
as a bearing to enable higher clamping forces.

Hub Ring Spacers
These spacers are designed to build a larger pocket
when using extra large collets. It also provides a

3.5 Specialized Mounting Conditions
Collet / Flange Plate Mounting
Some wheels may be centered using the lugholes and
center bore with a flange plate and collet. It is important
that a back mounted collet be used to support and center
the wheel when using flange plates.

The correct flange adaptor setup is determined by the
following:
Measure and set the bolt circle diameter and
number of studs to use against the lug holes.
Set the number of lugholes as follows:
A three-lug wheel uses three studs.
A four-lug wheel uses four studs.
A five-lug wheel uses five studs.
A six-lug wheel uses three studs.
A seven-lug wheel uses seven studs.
An eight-lug wheel uses four studs.
Choose the correct taper design of flange studs
to fit the wheel lug seats. The mounting area
of the flange stud must match the design of the
wheel’s lughole seat or depression.
The flange plate must be able to apply pressure to the
center of the wheel while maintaining perpendicularity to
the shaft.
If the lug seats are unevenly machined or
worn, an optional universal flange adaptor with
compressible studs or bolt on lugs may be used
to more accurately mount the wheel with the
collet.
Flange plates are useful when the wheel cannot be
properly centered off the hub bore with a collet alone
