Frangibolt® Washers
The Washers used in the Frangibolt assembly are an important part of
the mechanism. They serve the following critical functions:
-
They distribute the relatively high recovery stress generated by the Nitinol
cylinder during actuation, on a much larger contact area.
-
They have minimum thickness so as to minimize the overall length of the
joint.
- They have chamfers specially designed to match fillet radiuses of NAS bolts (at the location where the bolt head meets the bolt shank).
-
They have tighter fitting inner diameters designed to clear NAS bolt shanks
while at the same time maximizing coverage of the Nitinol cylinder.
