    Can anyone tell me what size of hole I need to drill for a 9/16" NPT, 1/4"BSPT and 3mm BSP tapped hole. Apparently there is a conversion guide somewhere but I cant find it. I would have guessed 1mm ish smaller than the required threaded hole, but ive since heard there is a conversion booklet. Thanks.
