Perfect for masonry projects
Used these extra-long bolts for passing through brick walls. The galvanization looks solid and the threads engaged smoothly.

Fast delivery
Arrived earlier than expected. The zinc coating provides good rust resistance for my outdoor gate installation.

Exact size needed
Hard to find extra-long studs in local hardware stores. These fit my structural framing needs perfectly.

Strong and durable
High quality steel. I tested the tensile strength on a few samples and they met the 8.8 grade specifications.

Good value but heavy box
The bolts are great quality. Only giving 4 stars because the packaging was a bit damaged during shipping, though the bolts were fine.
