Shoulder
Nut Eye Bolt ---
Installation for Angular Loading |
|
IN - LINE 
|
-
The threaded shank must protrude through the load
sufficiently to allow full engagement of the nut.
|
-
If the eye bolt protrudes so far through the load
that the nut cannot be tightened securely against the load, use properly sized
washers to take up the excess space BETWEEN THE NUT AND THE LOAD.
|
-
Thickness of spacers must exceed this distance
between the bottom of the load and the last thread of the eye bolt.
|
|
-
Place washers or spacers between nut and load so
that when the nut is tightened securely, the shoulder is secured flush against
the load surface.
