Need a source for safe lock mounting screws
They are for standard "magic footprint" locks. 1/4"-20 Phillips head, but here's the kicker...factory screws have heads of around .312" diameter so they don't bind against the wheels. The smallest heads I have found so far are allen socket cap screws with .368" diameter heads, and they bind the wheels. Even standard fillister head diameters are larger than that, so they won't work either.
Any help appreciated. I'd like to buy boxes of 50 or 100 in various lengths, and have no desire or need to buy complete mounting kits from S&G or LaGard. After all, they must be sourcing them from somewhere.
