Open End vs Closed End

• Closed end: fixed depth, no screw protrusion
• Open end: allows extended screw length

How It Works

The binding post (female part) and slotted screw (male part) work together to create a secure and reusable fastening system. The screw threads into the post, clamping materials together while maintaining a clean and finished appearance.

FAQ

Q: What is a closed end binding post?
A: A closed end binding post has a sealed bottom that limits screw depth and prevents the screw from extending through the post.

Q: When should I use closed end instead of open end?
A: Closed end posts are ideal when a clean appearance and controlled screw depth are required.

Q: Are closed end binding posts the same as Chicago screws?
A: Yes, they are commonly referred to as Chicago screws or binding posts.
