Washer
Fixing anchors - anchor types used
FireMaster blanket is norm
ally held in place using 3mm
diameter fixing pins over which the blanket is im
paled.
A friction fit washer secures the blanket onto the pin.
The standard recommended fixing method for aluminium
substrates is a bi-metallic anchor system. This consists of a
3mm diameter mild or stainless steel shaft that is screw
threaded into an aluminium boss which can be CD welded
to aluminium. The blanket is usually held in place with a
38mm diameter mild or stainless steel friction fit washer.
Smaller diameter washers m
ay also be used.

ation sheets, throughout
