Good match for antique piano

Original square head blots went missing to attach the pedal lyre underneath our pre-civil war 1857 Steinway & Sons square grand piano. Didn't feel right purchasing bolts from Home Depot or Lowes because we wanted to match bolts as close as possible to the original hardware of the time period. We searched all over the country and Old West Iron's bolts were the closest match we could find (almost identical), and we thank you SO MUCH for keeping history alive! Cheers from California.

Great product!

The bolts, washers, and nuts will work out perfect for mounting my old post vise to my workbench. Thanks!
