When using a Gasket or Interposed Sheet, the hole should be sufficiently larger than the outer diameter of the stud retainer to allow free entry of the retainer
* An oversized panel hole allows the stud to float which can compensate for panel-to-support misalignment. Do not use with 1219-R snap ring retainers.
9906-RS HAND TOOL is used to push the retainer over a Tapered Mandrel (included) and over the cam end of the stud until it reaches the undercut. Once the retainer reaches the undercut, it snaps back to its original size and prevents the stud from coming out of the panel.
Any flat block may be used to support the Ring Head, Knurled Head, and Tamper Resist Studs while the retainer is attached.

In this case, the 127H Half Grommet Retainer is flattened against the underside of the panel and can cause a gap between the panel containing the stud and the support containing the receptacle. Dimpling the support will allow the panel and support to come into direct contact by allowing the retainer to fit in the dimple. See S-Spring Receptacle Dimpling Tool. |
1271 Retainer wall thickness is absorbed by gasket, interposed panel, or by dimpled support. |
Underside of panel hole is counter bored to depth equal to 1271 Retainer wall thickness. |
* If application requires, size hole +.005/+.010 larger then Dim. A Note: Dimpled panels require dimpled supports. |
