Only thing to watch is try and use a longer starter bolt with a plain section at the chamfered head end. The threaded section of a UNC bolt, as shown in the Moss drawing, is slightly undersize for the Dzuz fastener. So when the grommet is compressed, the Dzuz won't go through.
Then a fine round file is needed to ease out the diameter, which weakens the grommet.
An Unbrako chamfered bolt held with an allen key is better than a slotted bolt that has to be held (from turning) with screwdriver.
Also, using a longer chamfered bolt and packing up the nut with washers keeps the spanner well above the hood. Many a newly sprayed hood has been chipped when the spanner has slipped off, as a fair amount of pressure has to be exerted.
Last pair I installed I took a fine hacksaw and divided the underside of the grommet into 4 sections. It then compressed with much less pressure needed.
