Stud Panel Preparation

Hex Recess, and Wing Head Studs

Note: Support Preparation is covered under Receptacle Installation

Stud Panel Preparation for 1219-R, 127P, 127H, and 1219-24

The drawings below all show the stud retainer being absorbed by either a counterbore in the panel, or by the space created through use of a gasket or interposed sheet between the panel and support. If neither option is feasible, the retainer thickness can also be absorbed by either the support or the receptacle when utilizing a 1219-L, 1218-P, 1219-QC4 or 1219-PS receptacle.

When using a Gasket or Interposed Sheet, the hole in the gasket or interposed sheet 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 an oversized panel hole with the 1219-R snap ring retainers.

1219-R, 127P, and 1219-24 Retainer Installation

The 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.

The 9902-1-1 BLOCK Side C is used to support the stud and panel while the retainer is attached.

1. Place the stud head in the block for support and place the stud through the panel.

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.
