ghostdog,I agree with your sentiments regarding bxxxx screws, and for that matter damaged to cover,lock and trigger plates caused by the use of incorrectly fitted/prepared turnscrews.
Scarcely an edition of the D.G.J arrives without evidence of damaged Screws/plates.For example;in the Spring 2011 edition, on page 37, a fine Baker shotgun is pictured with a a"butchered screw".To make matters worse the screw slots are out of line, another pet peeve of mine.
In the winter 2010 D.G.J page 30 we see the damage to the bottom plate of Newton boxlock Caused by use of a badly prepared/fitting turnscrew[This kind of side-slip,mishap can be avoided by simply filing a radius on the outside edges of your turn screws].In this example the sharp edge left on a turnscrew gouged an arc of metal from the trigger plate.This same illustration highlights the adverse appearance of misaligned screws.
As recommended by Dick Jones,Welding up the damaged screws and recutting the slot so as to be,"in correct alignment after assembly",followed by polish and re engraving to match the origional screw,is an excellent method.
