I've been puzzled for many years... the local hardware store has many "standard size" woodworking/wallboard fasteners/screws.... 1", 1.25", 2", 2.5" and so on. Rarely do I see 1.5" screws... yet 1-5/8" screws seem to be one of the main sellers (e.g. for sheetrock/wallboard fastening). Why is that? why not 1.5" ?

It think it simply has to do with board thicknesses. 2x4's are 1-1/2" thick. A 2x4 with a 1/4" sheet can accept a 1-5/8 screw without pass through. Yet two 3/4 boards (1 x whatever or plywood)will not allow a 1-1/2" screw to be used without some danger of pass through. So I see it as about 1-1/2" long screws just not moving enough volumn in the market to warrant stocking.... we can blame the bean counters...

Now in machine screws that is an entirely different matter. 1-1/2 is a very common size in socket heads, hex heads, shoulder bolts, and most all other types.





The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
