Steel Ball Plungers
Locking Element
 |
The wrench slot on the ball end only of Ball Plungers with #4, #5 or
#6 threads has been eliminated.
Plungers may be ordered with or without the locking element. Plungers
without element are the same price, but are considered "specials" and
cannot be returned. We recommend using without the locking element for
applications in aluminum.
To prevent possible spring damage, use of a Northwestern
Wrench is recommended when installing from plunger end.
End pressures are given in pounds. Full pressures are the force pounds
needed to move the nose the distance shown in "C"
columns.
The nylon locking element holds the plunger body securely in place without
the need for lock nuts or other devices. We recommend a 90° countersink
1/32" larger than the major diameter of the mating thread to prevent
damaging the element.
All parts conform to TCMAI/NIJFCM standards
*These
Ball Plunger part numbers have a nylon patch as the locking element.
All others have a pellet.
