I wished I knew of your site and products when building my log house. The couple things I recently purchased were excellent in appearance and quality.

Thank you so very much Mark !

Recent purchase
Great product. Fits the build perfectly for my project, however, I was shorted one !/4' X 20 square nut! Fortunately, I ordered a couple extra!

As advertised
Bought hardware from OWI to finish a hobbit door for my daughter's wedding. They add just the right touch of rustic authenticity and literally pull the project together.

Round, black, flat
What can I say - they were washers. Perfectly round, perfectly black, and perfectly flat. Perfect.
