Gypsum board installation requires screws to penetrate wood studs to a specific depth to ensure proper anchorage and structural support. The correct penetration depth of 5/8 inch is designed to securely hold the gypsum board without compromising its integrity or the strength of the assembly. This depth ensures that the screw engages sufficiently with the wood substrate, allowing for the board to be adequately fastened and helping to prevent any movement or sagging over time.

By using screws that penetrate to this depth, installers can create a secure and stable finished surface that is less likely to experience issues such as popping or separation from the framing. The specified depth of 5/8 inch is in accordance with industry standards and ensures optimal performance of the assembled system. Choosing a depth that is too shallow or too deep could lead to inadequate support or damage to the gypsum board, which is why 5/8 inch is considered the standard for this application.
