I was doing a bit of tidying up work on the fuel tank which involves inserting some bolts vertically upwards. The problem with this – as I learned before – is that, under the influence of gravity, they will drop back into the socket which doesn’t leave enough thread protruding to bite into the nut.
Following the principle of the sump plug socket I put a slice of fuel hose into an 11mm socket.
The bolt now sits on top of the fuel hose with the full amount of thread available.
Although someone had painted the heads silver, the original rear wing retaining screws were rusty – to the point one had seized fast and had to be cut out when we took the wings off during the rechassis.
SPOG do replacement stainless screws for these so I picked up a pack.
As we’d done the hard work when we took the wings off, and had reassembled using copper grease, the old screws came out one at at time to be replaced with a new one.
As the rivnut at the bottom of the offside wing had been seized to the screw and had come out I used a flanged stainless nylock nut for that screw. (Standard M5 0.8 thread.)
