Stud Panel Preparation
for All Studs Except Flush Head and Ring Head

Note: Support Preparation is covered under Receptacle Installation

Stud Panel Preparation With 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.

for 1219-R, 127P, 127H,
and 1219-24 		Gasket or Interposed Sheet

The hole should be sufficiently larger than the outer diameter of the stud retainer in order to allow free entry of the retainer.

Oversize Panel Hole
For 127P and 127H 		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.

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

  1. Place the retainer on mandrel as shown.
  2. Align ring or spring ends so that they will miss the stud cam.
  3. Place mandrel in end of stud cam.
  4. Place tool over mandrel
  5. Push retainer until it is seated in stud undercut.

9906-RS HAND TOOL: Spreads the inside diameter of retainers over stud shanks and then pushes them into stud undercuts.

9902-1-1 BLOCK: Nests stud heads during installation. (Any flat block may be used for 122J-R ring head studs.)

The installation of any of these retainers requires two tools.

The 9906-RS-xxx-BB 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 9902-1-1xxx-BB Side C is used to support the stud and panel while the retainer is attached.

Installation of the 127H Half Grommet Retainer requires two tools.

The 9916-5-1xxx-BB is used to flatten the grommet against the panel while the 9902-1-1xxx-BB Side C is used to support the stud and 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.

The triple-x (xxx) in the tool part number stands for the stud size number: i.e., 3, 4, 5, or 7 (for 65).

Stud Panel Preparation With 1271 Full Grommet

Full Grommet being Absorbed by gasket

1271 Retainer wall thickness is absorbed by gasket, interposed panel, or by dimpled support.

Oval Head Stud using a 1271 Full Grommet Retainer
Installation of a 1271 Full Grommet Retainer is a multi-step process and requires several different tools.
  1. A 9916-1-1xxx-BB is used to set the grommet in the hole while a 9902-2-1xxx-BB is used to support the panel and grommet for the set operation.
  2. A 9916-3-1xxx-BB is used to clinch the grommet around the stud while a 9902-1-1xxx-BB Side C is used to support the stud and panel.

Installation of a 127S-A Thick Panel Grommet Retainer is a multi-step process and requires several different tools.
  1. A 9906-A-xxx-BB is used to flare the grommet away from the stud while the 9902-1-1xxx-BB is used to support the panel, stud, and grommet.
  2. A 9916-3-1xxx-BB is used to clinch the grommet while a 9902-1-1xxx-BB is used to support the panel, stud, and grommet.
