1. Select receptacle
Choose a receptacle from
pages 380-384
2. Select retainer and
accessories
from page 385 and note any
adjustment values
3. Specify stud length
Calculate the total material
thickness (TMT) using the formula
given for the receptacle selected.
Find the range of TMT using the
stud length selection table (left)
using the column (A, B, C, or D)
given for the receptacle selected,
find K
4. Complete the stud part
number
by specifying the head style H,
stud length K, and material M
Example:
For rivet-on with base receptacle
82-35-302-15 use column D
For TMT value calculated as 5.2
(.206), K = 200
For slotted head style in steel
material, completed part number:
82-11-200-16
A complete example can be found on
page 377

1. Select receptacle
Choose a receptacle from
page 388-390
2. Select retainer and
accessories
from page 391 and note any
adjustment values
3. Specify stud length
Calculate the total material
thickness (TMT) using the formula
given for the receptacle selected.
Find the range of TMT using the
stud length selection table (left)
using the column (A, B or C) given
for the receptacle selected, find K
4. Complete the stud part
number
by specifying the head style H,
stud length K, and material M
Example:
For rivet-on with base receptacle
85-35-295-15 use column C
For TMT value calculated as 5.2
(.206), K = 200
For slotted head style in steel
material, completed part number:
85-11-200-16
A complete example can be found on
page 377

NOTE: Adjustment Formula
When using a stud ejector (ejector
spring and wear washer), add 0.8
(.032) to your Outer Panel Thickness
or Total Material Thickness.
When using a wear washer, add 0.5
(.020) to your Outer Panel Thickness
or Total Material Thickness.
1. Choose a receptacle (note any frame
thickness limitations).
2. To select a stud,
a) measure your Outer Panel Thickness
or Total Material Thickness (note
under receptacle part number will
tell you which to use).
b) if adjustment formula is shown
under receptacle part number apply
this formula to your measurement.
c) use measurement (or adjusted
measurement) to find part number
in table, pg. 273 under stud head
style you want.
3. Choose a retainer.
4. Order each component and tool (if
required) separately by part number.

Medium Series, 1/4-turn Studs, Snap-in Studs
and Fully Retracting Stud Assemblies
To select correct fastener
1. Choose a receptacle. (Note any frame thick-
ness limitations).
2. To select a stud,
a) measure your Outer Panel Thick-
ness or Total Material Thickness
(note under receptacle part number
will tell you which to measure).
b) if adjustment formula is shown
under receptacle part number,
apply this formula to your
measurement.
c) if sealing washers, stud ejector
springs or wear washers will be
used, apply proper adjustment
formulas to your measurement.
d) when using snap-in studs, add an
additional 0.5 (.020) to the Total Material
Thickness or Outer Panel Thickness, as
required by your choice of receptacle.
e) use measurement (or adjusted
measurement) to find part number in table
(see pages 282 and 283) under stud head
style you want. For snap-in studs, add a -1
suffix, ie. 82-11-180-16-1.
3. Choose a retainer.
NOTE: Snap-in stud assemblies do not
require a separate retainer.
4. Review the stud installation procedure.
5. Order each component and tool (if required)
separately by part number.
1/4-turn and Snap-in Studs
Fully-retracting
• Permits sliding applications
• Full stud retraction assists in panel-to-frame alignment
• Pre-assembled to speed installation
• Installation options—Press-in or Flare-in
• Black or bright finish
• Tool operated
To select correct fastener
1. Choose a receptacle (note any panel or frame
thickness limitations).
2. Select one of the following stud assemblies:
Press-in
a) Use your Outer Panel Thickness or measure
your Total Material Thickness, as required
by your choice of receptacle.
b) If an adjustment formula is shown under
the receptacle part number, apply this
formula to your measurement.
c) Use measurement (or adjusted measure-
ment) to find stud part number in the table
on page 282.
Flare-in
Measure your Outer Panel Thickness and use
Table located at bottom of page 284 to deter-
mine which column (I or II) you will
need in table on page 283.
Follow steps a) and b) at left and use your
measurement (or adjusted measurement) to
find stud part number in table on page 282.
3. Review the stud installation procedure. Order
each fastener component and installation tool
(if required) separately by part number.

Installation Guidelinesfor SOUTHCO® Self-Clinching products
Self-clinching product installation is offered on these
SOUTHCO® products, making them easy-to-use captive
panel fasteners:
When pressed into a properly prepared hole, self-clinching captive
fasteners cold-flow (move) the panel material into the retaining groove of
the fastener. This material then retains the fastener in the panel.

Successful press-in installations depend on:
Material:
The hardness of the panel material must not exceed SOUTHCO®
recommendations. If the panel is too hard, the fastener will not install
correctly.
Installation Holes:
Mounting holes may be drilled, punched, or cast.
• Holeedge:thetopholeedgemust
be sharp but with no broken edges.
Do not chamfer or debur edge.
•Punchedholes:useapunchanddie
with a small clearance to minimize
the rollover and fracture angle.
•Holediameter:measurethehole
diameter at the panel surface on
the side on which the fastener will
be installed. The diameter must be
within SOUTHCO® specifications for
that product.
- If the hole is too large, not
enough material will flow into the
retaining groove and the fastener may not be retained adequately.
- If the hole is too small, the fastener will not fit and installation may
become difficult and unsafe.

- Installing too close to the edge will cause the material to flow in the
opposite direction, deforming the edge of the panel. To install closer
to the edge, you may need to restrain the panel edge.

Panel Thickness:
The thickness of the panel at the mounting hole location must meet or
exceed Southco’s stated minimum recommendations.
If the material is too thin, panel deformation and/or damage to the
fastener may result.
Installation is fast and easy if you follow these tips:
How to install: Use the recommended force where noted and a proper
back-up tool.
- use any parallel-acting press
- use a punch whose diameter is larger than the head of the fastener
Installation Force: Proper installation requires an even distribution of
adequate force. It does not depend on the distance the fastener is pressed
into the panel.
- Southco does not recommend using a hammer. The impact force
does not provide an even distribution of force to allow the panel
material to completely flow into the fastener’s retaining groove.
- Installation force varies from application to application,
depending on the criteria noted above.
- On parts without a collar to provide a hard stop, press-in until the
edge of the knurl is just barely visible.
When to Install:
Installation is recommended after plating or finishing has been applied to
the panel.
The hole diameter must meet specifications
before finish or plating is applied.
- Do not over-install parts. This interupts
the material and will reduce the
retention strength.
