3/4" x 10" hot dip galvanized J Bolts are installed in wet concrete and are often used to attach sill plates to the foundation walls as well as supporting post bases, poles, and more. Our high quality anchor bolts are domestic products that are proudly made here in the USA. These J Bolts should be used with the correct hot dipped galvanized nuts and washers. When the concrete is still wet, the J hook anchors are typically hooked around rebar or another securing piece for added stability.
