Follow these instructions for a superior
installation of both plain swage standoffs and knurled swage standoffs.
Knurled swage standoffs offer more holding power than plain standoffs,
and eliminate electrical connection breaks due to loosening and spinning
of the standoff because of high torque stresses.
HOLE SPECIFICATIONS
Plain Swage Standoff
A plain swage standoff (no knurl) requires a
STRAIGHT HOLE. The hole diameter in the board or panel is the same as
the shank (or shoulder) diameter of the standoff with a tolerance
of +.003"/-.000" (+.076 mm/-.000 mm).
Partial Knurl or Full Knurl Swage Standoff
A partial knurl or full knurl swage standoff
requires a STRAIGHT HOLE in a printed circuit board. The hole
diameter in the board is .010" to .012" smaller than the shank
(or shoulder) diameter of the standoff with a tolerance of
+.005"/-.000" (+.13 mm/-.000 mm).
METHODS OF
INSTALLATION
Swage
While some dimensions of
the punch and anvil change with the size of the swage standoffs, the
following dimensions remain constant:
-
The punch is 2.5" in
overall length and .5" OD
-
The anvil is 1" in
overall length and .5" OD with a 1/2-24 external thread
-
Punch and anvil part numbers for
swaging
are listed on the individual pages of plain and partial knurl swage
standoffs
Flare
-
Flare tool is not supplied
-
Flare angle should be same as
countersink angle
-
For flush flaring into countersunk hole
use shank length .020" shorter than board thickness
