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.
Q: What wrench size fits the M10 head?
A: For an M10 hex bolt, you typically need a 16mm wrench or socket.
Q: Is the thread full length or partial?
A: These are fully threaded studs designed for wall-passing applications.
Q: Do you sell matching nuts separately?
A: Yes, compatible hex nuts are available in our related accessories section.
Q: Can I cut these bolts to a custom length?
A: We do not recommend cutting as it may compromise the structural integrity and thread quality.
Q: Are these suitable for outdoor use?
A: Yes, the zinc galvanized coating provides corrosion resistance suitable for outdoor environments.
