Which hinge should be used to fasten a hinge to a wood gate post when the bolt must pass through the post?

• A. Butt hinge
• B. Lag and strap
• C. Bolt and strap
• D. Strap hinge

Answer: (C)

When the bolt must pass through the post, you need hardware that is designed for through-bolting. A bolt and strap hinge is built for exactly that: a through-bolt goes clean through the gate post, and the strap helps spread the load along the post, giving a strong, stable connection that resists movement and sag over time. This setup is ideal for heavy wood gates that face side-to-side forces and wind. A butt hinge is typically mortised into the post and gate and relies on screws, not a bolt passing through the post, so it doesn’t meet the through-post requirement. A strap hinge by itself is usually surface-mounted and doesn’t inherently ensure a through-post bolt. Lag and strap uses lag screws rather than a through bolt, which also doesn’t satisfy the through-post connection.
