Now the Screws. from www.modelfixings.co.uk
MF-CS-16s M3 (3mm)x10 stainless steel countersunk screws (these use a HEX spanner to drive them not a pozi or phillips or slot)
You do of course have to be prepared to adjust the hight of the plastic turrets that they will be fixed to. The screws are NOT self tapping but they have given me no problems and grip well although every fixing on my Tanks is always bolstered with a liberal dose of THREAD LOCK. I hope that helps.
