The pocket depth for the button punch snap lock when applied to 24 gauge sheet metal is 1/2 inch.

• A. True
• B. False
• C. Not standard
• D. Unspecified

Answer: (A)

In this context, pocket depth is the distance formed inside the seam to receive and secure the snap lock. For a button punch snap lock applied to 24 gauge sheet metal, the standard pocket depth is half an inch. This depth provides enough engagement for a reliable lock while still matching the material’s thinness, so the bend and lock don’t risk tearing or binding. Because this is a defined fabrication standard for 24-gauge material, the half-inch pocket depth is the expected specification. Using a different depth would lead to an improper fit or compromised performance, which is why the statement is considered correct.
