Re: Door hinge bolts

Martin had me scared with your advice for a second there...then I got to the "however" part..wheeeew..running a fine thread tap thru a coarse thread hole..real risk of breaking a tap in there..
A fine thread 3/8-24 drill hole size is .3320
A coarse thread 3/8-16 drill hole size is .3125..
talk about making a mess of the threads..I've seen it done..
