As standard the holes in the E Speed Hangars are 3,1 mm while the
fastening screws are 2,8 mm (approx - all is imperial sizes). This
causes the hangars to move around a little. Now, you can fix some
of this by using countersunk screws in stead of cap head screws. However,
as you can see on the picture below there's not enough room for two
We therefore simply put them in the drill, and use a file to shave
off some. Reduce the head diameter from 5,7 mm to approx. 4,5 mm.
(Preferably use longer screws, so you can also put a securing small
nut on the underside)
Finished. The sunk heads keep the hangars perfectly in place, without
the screws coming into conflict with each other.
