I plan on using Gargraves track for my layout build (in addition to tubular). I bought these 2 mm x 12 mm pan head screws as an alternative to #4 x 3/8". I think they'll look better. They definitely require a #1 Philips bit for driving them. Gargraves wood ties may still require pre-drilling but I'll bet the these can be driven right through the plastic ties w/o problems.
