Hello Neal and Beverly:

Have been posting on "travel trailer forum", but thought this may be the quickest way to find out this information. I am about to replace all butyl stripping used around windows of my recently purchased 1980 Hi Lo. The 1" pan head square drive screws are to be replaced with stainless steel screws. Locally... these are not available. My drive will be 35 miles one way to purchase these items.

Can you tell me if the size of these screws is a No 10 x 1" lg." , or No. 8? I can buy them as a bulk item. Thanks Dabbler
