5/16" Dia. Hammered Square Head Bolt

3 reviews

Bolts are typically used for fastening items together. Both used for structural and decorative applications. Our square bolts appeal more to a rustic design especially with our texture of hammered or pyramid. These square head bolts add just the flare you need for your project. When purchasing nuts and washers with this item you will want to select the same size as the diameter of the bolt.


We recommend using 3/8" diameter and above for structural applications.

Authentic looking

We bought an old farm pump and one bolt was missing. We stumbled upon this site while looking for old bolts and nuts. We bought the "rusty" finish and it matches our old pump perfectly. We need 2 more so we will be ordering again. It took some time to receive order but that information was clearly stated on their webpage. Well worth the wait.

Real as real can be

These 5/16 inch bolts by 6 inches long are to go with the 1 1/2 square hammered black washers to secure a 24 inch by 6 inch thick log to a wall as a coat and gun holster rack. The realism is beyond today back to 1845 from the town Black Smith's shop. Can't get better than these. Thank you, Jerry
