[Healeys] Fender Screws

[Michael Salter]

Hi Michael,
Regarding "Still a little confused about that 1/4 inch self tapping sheet
metal screw though."
Just to clarify ... The screw that I'm trying to describe is not a self
tapping screw. It is a countersunk Phillips head 1/4" UNF thread.
The part number is CMZ0410 meaning it is a countersink head zinc plated
Phillips 4 sixteenths in diameter and 10 sixteenths long.

It is #46 in this image and it screws into the tapped plate #45 (14B2546)
and it was used on both sides on all models from BN1 - BJ8.
The countersunk Phillips head is hidden by the cockpit combing and the
interior trim panel.
The tapped plate which is about 2.5" x 1" x 1/8" thick is located on the
outside of the fender flange and its purpose is to hold the fender tight to
the inner body while clamping the shroud.
>From memory the screw passes through the first screw hole in the fender
flange rearward of the door shut post.
