I can confirm that HomePro at Rama 3 has lots of screws.

Either the hardware screws ore any other suggested are available.

Thailand is the only place that I haven't had problems finding a screw!

When I had my home built in Thailand, they found screws for the door hinges, but then drove them in with a HAMMER!! Go figure. You ever try to unscrew a bent up wood screw from a hinge, not easy to do.

Never had a problem buying screws. Mom and Pop shops have them, you just need to ask. The big hardware shop on the left as you drive into Ubon from Det Udom has little plastic boxes of them either all the same type and size or assorted.

WEll thats funny I got two tins one full of different size nails and one full of screws and rawl plugs.

gummy ....short or long (time) screw??

I see a shop on Rama 4 that sells screws. Every kind imaginable.

In the area across the road from the BMW Dealer.

Not sure of exact location but you can find it in that area.
