zinc plated, chromate plus sealer or
stainless steel
1. Determine your outer panel and
frame thicknesses:
Outer panel P =
Frame thickness F =
2. Choose your receptacle
3. Choose the retainer style
4. Find the correct constant in table
opposite using the receptacle and
retainer selected
5. Add outer panel thickness
(P), frame thickness (F), and
the constant found in step 4 to
determine your total material
thickness (TMT)
TMT = P+F+Constant
6. Find the TMT value in the ranges
given in Column 1 in the part
number table
7. Confirm that the outer panel
thickness P does not exceed the
value given in Column 2. This will
confirm that your retainer will install
properly beyond the last thread and
retain your screw to the outer panel
8. Going across the row in the part
number table, find the part number
that matches your desired head
style
Notes
For full screw retraction, B must be
less than inner panel thickness plus
receptacle height
For stainless steel screw (slotted,
wing and knurled ONLY) replace last
2 digits of part number with “12”.
