You are fastening a hinge to a wooden post. If the bolt must go through the post, what type of hinge would you use?

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

Answer: (D)

When the bolt must pass completely through the post, you need a hinge built for through-bolting. A bolt and strap hinge fits that need: the strap part attaches to the gate, and a bolt goes through the post to secure the hinge firmly on the other side. This setup provides a strong, through-the-post connection that can resist pulling and torsion from the gate. Strap hinges by themselves are mounted with screws along the surface and don’t accommodate a through-bolt through the post. Butt hinges are typically mortised and fastened with screws into the wood, not through the post. Lag and strap relies on lag screws into the wood rather than a through-bolt, so it won’t offer a through-post fastener.
