In the past there were studs available in the 5F series which had grommets attached.
This is the second way of installing the 5F series studs besides using a retaining washer.
These versions are no longer available, atleast not in their pre-assembled condition.

It is still possible to obtain the same mechanism but for that you need to buy also the grommet next to the stud.
Let us explain how you can identify the correct stud and grommet product number that is replacing the old combined product.

Firstly we would like to explain to you the old part number.
The old part number has 4 parts, 3 of them are divided by dashes and 2 letters at the end.

The first part is to identify the head style. There are 2 codes:

  • 5S34      Slotted recess head style
  • 5S54      Cross recess head style

The second part reflects the dashlength of the stud. This number is linked to the total thickness that needs to be clamped. Be advised that this number also contains the grommet!

The third part is the number showing which grommet is used. There are 4 different numbers that are used for the grommet: 5, 6, 9 and 11.
Each of them is used for a certain panel thickness. These numbers are still used in the new product codes for the seperate grommets.
However you need to pay close attention! The grommets have changed, and now have a bigger rim that is 4 times larger than before. In the old part number the grommet size was already included in the stud length number. It was 1 dashlength longer then when not using a grommet. As the grommet is larger, the stud length number needs to be increased by 3!
The alternative solution is to opt for a different quarter turn setup.
Namely to have the use of the grommet removed. The correct studlength is then obtained by deducting 1 from the stud length.

The last part are the 2 letters at the end of the product code. These are showing which material the stud is made of. There are 2 possible values

  • AA       steel / cadmium plated
  • BB       stainless steel

The new stud part numbers, are made to reflect both style and material grade.
The star is to be replaced by the dashlenght number of the stud.

  •  V5S5-*AGV          Slotted recess head style in steel/zinc plating, CrVI free
  • V5S35-*BP            Slotted recess head style in stainless steel
  • V5S21-*AGV        Cross recess head style in steel/zinc plating, CrVI free
  • 5S15-*                    Cross recess head style in stainless steel

The part number of the grommet has changed to 5S72-*-1AA, with on the star the grommet identification number.

For example: 5S34-8-5AA = V5S5-11AGV + 5S72-5-1AA

5S34    V5S5     slotted head
8           11            dashlength
5           5              grommet type 5
AA        AGV      material grade (to be found on new stud)

Please find enclosed the general table showing which are the combinations of stud and grommet replacing the old references. The star takes the place of the dash length.
