I want to order some hardware to start making some holsters, what do you guys use the most as far as T-Nuts, thread size, and height wise? I'll be using mostly 7-8 oz leather double thickness. Im guessing for attaching loops on IWB holsters Id probably want like 1/8 or 3/16 heightwise. But what about for a tension screw?Im guessing on this and would rather not order the wrong stuff so Id appreciate some help from you pros. Also what else should I get while Im at it, I figure some countersunk finish washers, and machine screws, thats another one, what lengths screws and what type of heads do you guys use most, slot,phillips, allen?
