Fitting Procedure
1 Drill a hole in the machine body/framework where the
rivet nut is to be fitted. De-burr hole edges.
2 Screw the rivet nut onto the mandrel of the installation
tool. The bottom of the mandrel should be in line with
the bottom of the rivet nut
66-A .
Fig 66.
3 Wind the body of the installation tool down the
threaded mandrel until it touches the head of the rivet
nut
67-B .
Fig 67.
4 Insert the rivet nut (assembled to the tool) into the
hole drilled in step 1.
5 Hold handle 68-C and at the same time draw the
mandrel into the installation tool by turning nut 68-D .
The rivet nut will contract in length and form an 'upset'
(smooth bulge) seating itself against the body/
framework
68-E .
Note: The thread of the rivet nut must not be stripped, take
care when 'upsetting' the rivet nut.
