Roof restraint straps sticking out

[Spinny]

I have some walls to be wet plastered which have roof restraint straps running vertically down the blockwork for 80mm from the ceiling. One in particular is bent at the bottom and with its screw head sticks out from the wall by 10+mm.

 

Any tips on dealing with this ? Presumably I can't just cut the end off ? Any way to bend it straight in situ ? Any flush screw head fixings for these things ?

I have previously taken the screws out one by one, used a countersink bit in my drill to countersink the fixing holes, and replaced the screws with countersunk.

 

The bent one, remove several of the bottom screws, ease it away from the wall but a block of wood behind and hammer the bent bit straight again.  Replace screws.
