4002 SERIES

QUICK OPERATING 1/4-TURN FASTENERS 4002 SERIES

The 4002 Series fasteners utilize a variety of grommets designated to reinforce the panel for added  strength. Certain
4002 series 1/4-turn fasteners are qualified to MIL-F-5591* specifications for sizes 5 and 7.

To Order a Complete Fastening System:

1. Select receptacle to be used. Stud part numbers vary depending upon the specific receptacle used.
2. Select style of stud to be used, then combine thicknesses of panel and frame to determine total thickness, “G”. Find
the specific stud part number adjacent to “G” Total Thickness column with respect to receptacle selected.
3. If you are ordering long studs (-16 or greater), you will need to order a Stud Retaining Ring. Shorter studs (-15 and
under) are self-captivating and do not require retaining rings.
4. A Grommet is required for all 4002 studs except Part Number 40S128. A choice of Flared or Retaining Ring Retained
styles are available.

*Meets the design, physical and performance requirements of MIL-F-5591. However, full mechanical properties testing may
not be performed on each production lot.

Assembly, P/N 40S37-[ ]—130°F.; all others 450°F.

Note: 4002 Series stud assemblies seat nominally flush with mating grommet. For Wing, Bail
Handle or Knurled Knob versions, top side protrusion is nominally equal to mating grommet “B” dimension plus the
height of the wing, handle or knob.

Specifications:

This series utilizes a variety of grommets which must be installed into the top panel. They significantly enhance the
system’s performance. Ultimate tensile strength: 1050 lbs. Working strength: 700 lbs. Stud grip increments: .030 inch.

Panel Preparation and Installation Data

(For Ring Retained Grommets) Plus Flush Grommets

Drill #30 (.1285) pilot hole. Enlarge pilot hole to .478-.473 diameter with hole saw HS-471. “P” maximum panel thickness
varies with grommet selected. Please see Page A-51 for tabulation.
Panels with thicknesses greater than “P” maximum must be back counterbored to a concentric .688 inch diameter with a
remaining material thickness not exceeding “P” maximum.
Note: Hole saws and counterboring tools are available as a convenience in selected
sizes. Please see Page A-55.

Ordering Information/ Stud Dash Number Selection

To Select Stud Dash Number

1. Stud dash number varies with receptacle used. This information must be known before proceeding.
Select receptacle from Pages A-48 through A-50.
2. Determine “G” thickness.
Notes:(a) Increase “G” to allow for thickness of paint or other finishes and for the
compressed thickness of any gasket.
(b) When selecting stud dash number, “G” must be increased for the following “Special” conditions.

“Special” Conditions	Increase “G” Thickness
4002 Series Ejector Spring installed	Add .021 inch
Snap-in Receptacle (P/N 40R 39-1-1AA) installed	Allow .020 inch for receptacle top side protrusion.
40R8 Series Receptacle Shims installed	For each shim used, add an amount equal to “A” max. shim thickness. (See Page a-48)
Plus Flush Grommets installed	For purposes of selecting stud dash number only, add “D” max. protrusion of grommet. (See Pages A-51 and A-52)
40S37 Stud Assembly installed with sealing gaskets	Add .045 inch

3. Locate “G” total thickness in the stud dash number table on the following

4. Then find the corresponding stud dash number in the column designated for the
receptacle
