Bolt head advertised size

The finish and appearance of the hardware was as pictured and exactly what I was expecting. The size of the head of the on the hardware wasn’t. When the heads were stamped to appear old and rusted and then colored it made the size increase by .030 to .050 witch wouldn’t allow an 4 or 8 point socket or open end wrench to be used. I had to go to a 12 point socket which didn’t have a lot of engagement with the flanks of the hardware and tended to damage the power coat or whatever the finish is. I had to install over 150 lags and an adjustable wrench was not going to cut it.

Keith, I'm sorry to hear you had a less than satisfactory experience with our product. Because these heads are hand hammered (not machine stamped), we allow for slight variations in exact size. It is nearly impossible to give exact sizes on hand hammered products such as our lags because one hammer hit can change the measurements slightly. We are transparent about this on our website, you can find this notice at the top of the "Square Head Lag Screws" landing page. Typically the sizes you ordered would fit with 9/16" 8 point and 3/4" 8 point sockets, I'm sorry this was not your experience. For the finish, you can touch up with a Flat Black spray paint, we like Rust-oleum. If there is anything else we can help you with, please don't hesitate to call or email.

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!
