For mandrel or mandrel follower spring selection, follow instructions above.

To find the correct part number of a mandrel for a particular application, read the instructions below after you have gathered the following 
information as per example alongside.  Answers for the example are shown in 

grey italic.

•

Subtract the minimum hole size recommended (AS REC.) in the fastener datasheet from the actual application hole size.

-example: 0.005.

•

Turn to the page with the ‘Mandrel Selection’ table for your fastener, selecting either the imperial or the metric dimensions table 
(pages 17-21). 

-example: page 17.

•

Staring with the ‘Standard Mandrel - Green’ section, find your fastener size in the left-hand column.

•

If you selected a nose jaw which place you fastener, you should now be able to find a line within your fastener section with the same ‘Ref
No.’ as that from the ‘Nose Jaw Selection’ table.

-example: 5.

This is your line ‘Ref. No.’ in which you will find both your mandrel and

mandrel follower spring part number. This line continues into the second half of the table for the ‘2nd’ and ‘3rd’ oversize mandrels.

•

Scan along the line to the ‘hole size’ columns and select which ever is the nearest or equal  to the figure calculated in step one. You may
now read the mandrel part number next to the ‘hole size’. 

-example: 07150-06104

For Chobert

®

and Grovit

®

only, most mandrels are also available in a ‘short reach’ version (see illustration on page 20). Short reach

mandrels are used to minimise the possibility of the mandrel head contacting a read obstruction. This would result in the underside of the
fastener head not seating properly on the application surface, causing a lack on clench in the joint.

•

Whichever size mandrel you settle on, you will also need to check the  ‘P’ figure against that mandrel is adequate. ‘P’ is the clearance
required for the mandrel head at the back of the application IN ADDITION to the length of the fastener protruding through the application,
as shown in the illustration on page 20.

•

You may now read the corresponding mandrel follower spring part number in the right-hand column of the table.

-example: 07150-06804

.

In all cases, satisfactory clenching of the joint should be assessed particularly if the size of the hole in your application is very close to the next
oversize hole condition, when it will be safe to select the greater size of mandrel to obtain a higher clench. REMEMBER that this will increase
the broach load and reduce the mandrel life.
